TRN Verification in the UAE — How to Verify a TRN or VAT Number on the FTA Portal

VAT verification in the UAE runs through one free tool: the Federal Tax Authority’s public TRN verification lookup on tax.gov.ae. A UAE VAT number is the 15-digit Tax Registration Number, so a VAT number check and a TRN check are the same job. Enter the number, clear the security code, and the portal returns the registered legal name and current registration status. No login, no fee. (FTA homepage, checked 4 August 2026.)

VAT number verification therefore has one destination and one direction of travel. There is nothing else to check, and nothing to search by company name.

VAT verification in the UAE: what the FTA lookup actually confirms

VAT verification is the act of putting a 15-digit TRN into the Federal Tax Authority’s public panel and reading back two things: the registered legal name and the registration status. A VAT number check UAE-side settles whether the registration exists and is currently live on the FTA’s own records on the day you run it — which is the fact an input-tax claim rests on. It settles nothing about whether the supplier has filed or paid.

Worked example. A Sharjah distributor receives an invoice for AED 210,000 plus AED 10,500 VAT from a new logistics supplier. The federal tax authority TRN verification panel returns a legal name one word different from the name on the invoice — the trading name, not the registered entity. The buyer holds the VAT element, asks for a corrected invoice in the registered name, and pays a week later with a clean Article 59 document on file. Had it paid on the original invoice and recovered the AED 10,500, a later disallowance would have carried a fixed penalty of 15% of the tax difference plus 1% per month under Table 1 item 12 of Cabinet Decision No. 40 of 2017, as amended by Cabinet Decision No. 129 of 2025 (issued 9 October 2025, effective 14 April 2026).

What is a TRN in the UAE?

A TRN (Tax Registration Number) is a 15-digit number the UAE Federal Tax Authority (FTA) issues to every business registered for VAT under Federal Decree-Law No. 8 of 2017. It identifies the registered business in every FTA interaction — VAT-201 filings, tax invoices, correspondence, refund claims, audit notices. TRN verification in the UAE is the 30-second habit that protects your input VAT: run any supplier’s number through the FTA TRN check before you pay. Use our free TRN verification tool to check any UAE TRN in seconds, read our VAT registration in UAE guide for the full walkthrough, or lean on our VAT services in Dubai to fold supplier TRN checks into your monthly reconciliation.

On the TRN meaning, there is less to it than the search volume suggests. The full form is Tax Registration Number, and the TRN number meaning in the UAE is simply that: an FTA-issued identifier for a registered taxable person. It is not a licence, not a credit rating and not proof that anyone has actually paid their VAT.

On format, one rule is published and one is only a pattern, and it is worth keeping them apart:

• 15 characters, exactly. This is the FTA’s own stated constraint — its verification field will not accept a number of any other length. Anything shorter or longer is a foreign VAT number, a typo, or not a TRN.
• Digits only — no letters, no spaces and no hyphens on official documents, whatever the invoice template does for readability.
• The 100 prefix is an observation, not a published rule. In practice, VAT TRNs issued to date open with 100, and it is a useful first-pass filter for spotting a mistyped number. The FTA does not publish this as a format specification, so treat a number that fails it as worth questioning, not as proven invalid — the lookup, not the prefix, is what settles it.

Example shape: 100 1234 5678 9001 (spaces shown only for readability — official TRNs are printed without them).

UAE VAT number verification: the rules, with sources

Everything below is taken from the instrument named in the right-hand column rather than from secondary commentary, because the administrative penalty table was amended in the last few months and a lot of what is still circulating online quotes superseded amounts.

One date is worth pinning down, because it changes several of the numbers above. Cabinet Decision No. 40 of 2017 is the administrative penalty regime, and it has been amended three times — by Cabinet Decision No. 49 of 2021, then No. 108 of 2021, and most recently by Cabinet Decision No. 129 of 2025, issued 9 October 2025 and effective 14 April 2026.

That last amendment rewrote Table 1 and Table 3 in full, so any penalty figure you find quoted on a page written before April 2026 needs re-checking against the consolidated text the Ministry of Finance publishes rather than being taken at face value. The figures in the table above come from that consolidated text.

And note where the invoice rule bites: an invoice that omits the supplier’s TRN is not a valid tax invoice under Article 59(1)(b) at all, which is why a TRN problem tends to surface as an input-tax problem rather than as a paperwork one.

How to verify a VAT number in the UAE

Most people arriving here typed something closer to “verify VAT number” than “TRN verification”, so it is worth saying plainly: in the UAE those are the same task. There is no VAT number sitting alongside the TRN. When the FTA approves a VAT registration it issues one 15-digit Tax Registration Number, and that number is what a supplier prints on an invoice under the heading VAT No., VAT Reg No. or TRN, depending on whose template they bought. A customer asking for your VAT number wants your TRN. A supplier quoting a VAT registration number is quoting theirs.

That matters because it rules out a search a lot of finance teams waste an afternoon on. There is no UAE equivalent of a national VAT-number directory you can browse by company, and no VAT number lookup separate from the FTA’s own tool. One number, one place to check it.

The check itself takes under a minute:

1. Open tax.gov.ae and find TRN verification in the quick links on the homepage. It opens as a small panel rather than a separate page, which is why people occasionally report not being able to find it.
2. Type the 15 digits with no spaces, hyphens or the letters TRN in front of them. The field rejects anything that is not exactly 15 numerals, so a VAT number of a different length is a foreign one, a typo, or not a VAT number at all.
3. Clear the security code.
4. Read what comes back: the registered legal name and the registration status. That is the whole of the answer — this is a TRN validation tool, not a credit report.
5. Screenshot the result, date it, and attach it to the vendor record.

Step five is the one that gets skipped and the one that pays. The panel gives you no reference number and keeps no history you can retrieve later, so if you do not save the result at the moment you run it, you have done the check but you cannot prove you did. A dated screenshot on the supplier file is what turns “we assumed it was fine” into evidence of reasonable care when someone reviews the return two years on.

One caveat on what a VAT number check actually settles. It confirms that the registration exists, that it belongs to the name shown, and that it is currently live. It says nothing about whether that supplier files returns on time or has ever paid the VAT they charged you. Those are their obligations, not yours — but if you want the fuller picture of what you can and cannot recover, our guide to input VAT recovery in the UAE sets out the conditions that sit behind the claim, and input VAT versus output VAT covers how the two sides meet on the return.

VAT number verification vs the FTA’s Status Check — two different tools

A recurring reason people conclude that VAT number verification is broken in the UAE is that they end up on the wrong FTA page. The Authority runs a service called Status Check at tax.gov.ae/en/statuscheck.aspx, and the name reads exactly like what someone hunting for a TRN status check would want. It is not that tool.

Status Check asks for an SRN — a Service Request Number — together with a security code. An SRN is the reference the portal generates when you submit a request to the FTA, so the page tells you where your own submission has got to. It has no view of another company’s VAT registration, and pasting a 15-digit TRN into it returns nothing useful. (Checked on the FTA site, 4 August 2026.)

The tool you actually want sits on the FTA homepage rather than on a page of its own. It appears in the quick links as TRN verification, opens as a small panel in place, and takes the TRN plus a CAPTCHA. That is why so many people report that they cannot find it: they are looking for a URL, and there isn’t a memorable one — there is a panel.

Worth noting alongside this, because it is the other half of the same confusion: the FTA has moved its actual services behind UAEPass sign-in, and the site says so prominently. Reading that banner, people reasonably assume every lookup now needs an account. The TRN verification panel is the exception — it is a public check, deliberately open, because the whole point of it is that a customer who is not the registrant can confirm a supplier’s number before recovering input VAT.

So the practical routing is short. Checking somebody else’s VAT number, or your own after issue: the public TRN verification panel, no login. Chasing a submission you have already made to the FTA: Status Check with your SRN. Anything to do with filing, amending or downloading your certificate: sign in to EmaraTax properly.

TRN vs TIN: are they the same in the UAE?

A TIN (Tax Identification Number) is the international term used in tax-treaty and cross-border contexts. In the UAE, for VAT purposes, the TIN is the TRN. For corporate tax, the FTA issues a separate Tax Registration Number in the same 15-digit format when you register under Federal Decree-Law No. 47 of 2022.

Quick reference:

How to check a TIN number online in the UAE

If you’re searching for how to check a TIN number online, here’s the short version for the UAE: your TIN and your VAT TRN are the same number, and you check it the same way — free, on the FTA’s public lookup, with no account. There’s no separate “TIN database” to search. The Tax Identification Number that turns up on international forms, treaty paperwork or a foreign client’s onboarding pack is simply your 15-digit TRN. None of the personal identity numbers a UAE resident carries — the Emirates ID number or the UID number on the residence visa — works as a TIN; those belong to the immigration system, not the FTA.

To check one online:

• Open the FTA portal and go to the public TRN verification lookup.
• Type in the 15-digit number exactly as printed — no spaces or hyphens.
• Clear the security code and read back the registered legal name and status.

If a foreign counterparty asks for proof of your UAE TIN, a screenshot of that result page usually settles it, alongside your VAT registration certificate. For the wider treaty and cross-border picture — including tax residency certificates under Cabinet Decision 85 of 2022 — see our TIN number in the UAE explainer and the VAT registration guide.

How to verify a UAE TRN on EmaraTax in five steps

The FTA migrated all VAT services to the EmaraTax portal in late 2022. The public TRN verification tool — the same one people search for as a trn check uae, “FTA TRN check”, “TRN number check UAE” or “VAT TRN verification” — sits inside it, no login required.

1. Go to tax.gov.ae and open the EmaraTax portal.
2. From the homepage, locate TRN Verification (no login required).
3. Enter the 15-digit TRN you want to verify.
4. Complete the CAPTCHA challenge.
5. The portal returns the registered legal name, TRN status (Active / Deregistered / Suspended) and registration date.

If the lookup returns no record, the TRN is invalid or never existed. If it shows Deregistered, the business is no longer VAT-registered and cannot legally charge VAT on new invoices.

Before you even reach EmaraTax, run the supplier’s TRN through our free UAE TRN verification tool. It checks 15-digit format, checksum and structural validity in one click, so you only spend EmaraTax CAPTCHA time on TRNs that pass basic format checks.

EmaraTax TRN verification: reading the result screen

EmaraTax TRN verification returns more than a yes/no, and the detail is where the value sits. When a number checks out, the portal shows the registered legal name, the TRN status and the registration date — and each field tells you something different.

The legal name is the one most people skip and shouldn’t. It has to match the name on the supplier’s invoice; a valid TRN attached to a different entity is exactly the pattern a reviewer flags. Status reads as Active, Suspended or Deregistered — only Active supports a clean input-VAT claim. The registration date matters when you’re checking an invoice dated before the supplier was actually registered, in which case they had no business charging VAT on it at all.

Two practical notes. This lookup replaced the old eservices.tax.gov.ae verification page when the FTA moved everything to EmaraTax in late 2022, so old bookmarks won’t work. And the result screen carries no permanent reference number — so screenshot it, date it, and file it against the supplier record. That saved image is your evidence of reasonable care if the registration status later changes.

Using the FTA TRN verification tool the right way

The FTA TRN verification tool is the official public lookup on tax.gov.ae, and it’s the only source that confirms a number is genuinely live on the FTA’s own records. It’s free, needs no login, and it’s the one to cite if a claim is ever questioned. Two things it deliberately doesn’t do, though, are worth knowing.

First, it checks one TRN at a time behind a security code — there’s no public bulk upload or API, so a vendor master of 300 suppliers means 300 manual checks. Second, it validates the registration, not the invoice: it can’t tell you whether the number was copied correctly off the supplier’s certificate in the first place.

That second gap is what our free TRN verification tool fills. It checks the 15-digit structure and format instantly, so you weed out the malformed numbers before spending security-code time on the official portal. Use the two together — our checker to catch typos in bulk, the FTA tool to confirm the survivors are active. Neither replaces holding a valid tax invoice, which is what the law actually rests the claim on.

Why doesn’t my input VAT recover without a verified TRN?

Under Article 55 of the VAT Decree-Law (Federal Decree-Law No. 8 of 2017), a registered business can only recover input VAT if it receives and keeps a valid tax invoice that meets the formal requirements set out in Article 59 of the Executive Regulations:

• The supplier’s correct, verifiable TRN, alongside their name and address
• The recipient’s name, address and TRN wherever the recipient is itself a registrant
• A clear description of the supply
• The VAT amount shown separately
• The supplier’s full registered name as on the FTA record

If the TRN on a supplier invoice doesn’t verify on EmaraTax — or the legal name doesn’t match the FTA record — the FTA can disallow the input VAT during audit. The cost lands on the buyer, not the supplier.

“

“We’ve seen Dubai SMEs lose AED 30,000–80,000 of input VAT in a single audit because supplier TRNs on invoices were either typoed or belonged to deregistered businesses. Verification at intake takes 30 seconds. Recovery after audit takes months.”

What one unverified TRN costs: a worked example

Abstract warnings about disallowed input tax rarely move anyone, so here is the arithmetic on a single realistic case. Every rate used comes from the penalty tables cited above.

A Dubai trading company files quarterly. In one quarter it books 240 supplier invoices and recovers input VAT on all of them. Three of those invoices come from a subcontractor whose VAT registration was cancelled part-way through the quarter, with a combined net value of AED 620,000. At the standard 5% rate, the VAT element the company claims is AED 31,000.

Nothing happens for over a year. Fourteen months after the return was due, the FTA opens a review, finds the supplier was not a registrant on the date of supply, and disallows the claim. Because the company never filed a voluntary disclosure before being notified of the audit, Table 1 item 12 applies, and it has two limbs:

• The disallowed input tax itself: AED 31,000 becomes payable.
• Fixed penalty, 15% of the tax difference: 15% × AED 31,000 = AED 4,650.
• Monthly penalty, 1% of the tax difference for each month or part thereof from the day after the return was due to the date the assessment is issued: 1% × 14 months × AED 31,000 = AED 4,340.

Penalties total AED 8,990 on top of the AED 31,000 repayment — call it AED 39,990 against an original claim of AED 31,000. And the meter has not necessarily stopped: under Table 1 item 9, unsettled payable tax attracts a further penalty of 14% per annum, for each month or part thereof, running from 20 business days after the assessment is received. Leave the assessment unpaid for three months and that adds roughly 3.5% of AED 31,000, about AED 1,085 more.

Now price the alternative. Checking three TRNs on the FTA lookup takes about ninety seconds and costs nothing. That asymmetry — a minute and a half against five figures — is the entire argument for putting verification in the accounts-payable workflow rather than in a policy document nobody opens. Our VAT penalties in UAE guide works through the other penalty categories in the same tables, and VAT return filing in the UAE covers where a corrected claim actually lands on the return.

How do I find my own VAT number?

Half the people searching for VAT number verification are not checking a supplier at all — they are trying to find their own number, usually because a customer has asked for it or an onboarding form has a mandatory field. The public lookup is no help here, since it only confirms a number you already have.

Four places hold it, in rough order of how quickly you will get to it:

1. Your VAT registration certificate. The TRN is printed on it. You can download a fresh copy from your EmaraTax dashboard at any time; our guide to the UAE VAT certificate download walks through where it sits in the portal.
2. The EmaraTax dashboard itself. The TRN appears against the VAT registration tile once the registration is approved.
3. Any tax invoice you have already issued. If your accounting system is configured properly, your TRN is on every one of them.
4. The FTA approval correspondence sent when the registration was granted.

If none of those produce a number, the likely explanation is that the registration was never completed, or it is still pending. A pending application returns nothing on the public lookup, which is what sends people hunting for a tracking page that does not exist. Check the application status inside your own dashboard instead, and if you have not yet registered at all, the how to register for VAT in the UAE walkthrough sets out the documents and the sequence. Should you be winding the registration down rather than starting one, VAT deregistration in the UAE covers the window and the monthly penalty that follows missing it.

TRN errors, decoded

How to apply for a UAE TRN (if you don’t have one)

If your taxable supplies exceed AED 375,000 in the past 12 months, or are expected to exceed it in the next 30 days, you must register for UAE VAT. Voluntary registration is available from AED 187,500.

1. Log into EmaraTax at tax.gov.ae (create an account if first-time).
2. Select VAT Registration from the dashboard.
3. Provide: trade licence copy, MoA (Memorandum of Association), passport + Emirates ID of authorised signatory, bank account letter, financial statements or turnover declaration.
4. Submit. The FTA’s own service page puts the application itself at roughly 45 minutes to complete and gives 20 business days from receipt of a completed application as the processing estimate. “Completed” is doing the work in that sentence — an information request restarts your wait, which is why document mismatches cost more time than the portal ever does.
5. Late registration (exceeding the threshold without registering) triggers a AED 10,000 administrative penalty under Table 1, item 3 of Cabinet Decision No. 40 of 2017, as most recently amended by Cabinet Decision No. 129 of 2025.

While the application sits with the FTA, the TRN status check that matters is the one inside your own EmaraTax dashboard rather than the public lookup. The public tool only recognises numbers that have already been issued, so a pending registration returns nothing there — which catches people out and sends them hunting for a separate TRN tracking page that does not exist. Watch the application status on the dashboard, answer any FTA information request quickly, and the number appears on the approved registration.

Can you find a TRN by company name?

This is one of the most common searches after TRN verification itself, and the honest answer disappoints people. The FTA’s public lookup is built around the number, not the name: you enter the 15-digit TRN and it returns the registered legal name so you can confirm the two belong together. It is a TRN verifier, in other words, not a directory you can browse. Searching a supplier by company name, or hunting for a large corporate’s TRN because it was left off an invoice, will not get you there through the portal.

What does work is going back to the source. The TRN belongs on every compliant tax invoice, so the fastest route is the invoice itself. Failing that, ask the supplier’s finance contact for the number or for a copy of their VAT registration certificate, then run TRN verification by company name in reverse — put the number in, check the name that comes back matches the entity you are actually paying. If a supplier is reluctant to give you the number at all, treat that as information in its own right and hold the input VAT claim until it is resolved.

What your tax invoice has to show

Every tax invoice you issue as a VAT-registered UAE business must show:

• The phrase “Tax Invoice” at the top
• Your TRN (clearly labelled)
• Your full registered legal name and address
• The recipient’s name and address, and their TRN wherever they are a registrant
• Invoice number, date of issue, date of supply (if different)
• Description, quantity and unit price of each supply
• The VAT rate, the VAT amount in AED, and the gross total
• A clear statement if the supply is zero-rated, exempt or reverse-charge

A simplified tax invoice carries fewer fields, and Article 59(5) of the Executive Regulation allows one in two situations: where the recipient is not a registrant, or where the recipient is a registrant and the consideration does not exceed AED 10,000. It is not available where the reverse charge mechanism applies. Either way the supplier’s TRN stays mandatory — it is the one field the simplified format never drops.

TRNs for free-zone entities, designated zones and group companies

Free-zone and designated-zone entities raise specific TRN questions in UAE VAT practice, and each one behaves a little differently.

A company licensed in DMCC, DIFC, ADGM, RAKEZ, IFZA, Meydan or SHAMS that isn’t in a designated zone just follows standard mainland VAT rules. Cross the AED 375,000 threshold and registration is mandatory, and the FTA issues a TRN in the same 15-digit format as everyone else.

Designated zones are the case people get wrong. The FTA’s official list — first set by Cabinet Decision No. 59 of 2017 and updated several times since — now runs to more than 20 free zones (DAFZA, JAFZA, Hamriyah Free Zone, Fujairah Oil Industry Zone and others), and supplies of goods between designated zones, or out of the UAE, can sit outside the scope of UAE VAT. But the entity is still usually VAT-registered for its in-scope supplies and holds a TRN. So don’t assume a designated-zone supplier has none — verify on EmaraTax.

Tax groups add another wrinkle. Two or more related UAE legal entities can form a VAT group under Article 14 of FDL 8/2017. The group gets one TRN, intra-group supplies are disregarded for VAT, and members give up their individual TRNs for as long as they stay in the group. Worth checking whether a supplier sits inside a group, because invoices may carry the group TRN rather than the trading entity’s name on every record.

Branches are the simplest case. A foreign company’s UAE branch registers under the parent’s commercial registration but gets its own UAE TRN — one that identifies the UAE branch, not the offshore parent.

How to add a customer or supplier TRN to your accounting software

Whichever platform you use, the supplier and customer TRN is a master-data field — not a transaction-level field. Best practice:

• Zoho Books: Customer / Vendor settings → “Tax Information” → enter TRN → set Tax Treatment (VAT Registered / Non-VAT Registered / Designated Zone / Outside UAE)
• QuickBooks Online (Middle East): Customer / Supplier → Edit → “Tax Info” tab → TRN field
• Xero (Middle East edition): Contact → Financial Details → “Tax Number” field, formatted as 15 digits
• Tally Prime (UAE release): Master → Edit → “Taxation” → enter TRN; required for VAT classification on every voucher
• Odoo: Contact → Sales & Purchase tab → “TIN” field (which represents the TRN in UAE context)

Once the TRN sits in master data, it flows automatically onto every tax invoice you issue or every purchase you book. That eliminates the typo class of errors.

TRN on imports, exports and reverse-charge entries

Reverse-charge supplies (imports of services, intra-GCC supplies, designated-zone movements) are accounted for under Article 48 of FDL 8/2017. The recipient self-accounts for both output and input VAT on the same VAT-201, but the TRN treatment isn’t the same across all three.

On imported services, the foreign supplier has no UAE TRN at all. Your accounting system should book it as “Non-VAT Registered” and apply reverse charge automatically, so the VAT-201 records the output VAT in Box 3 and offsets it with recoverable input VAT in Box 10, subject to recoverability. GCC intra-group supplies work differently again — implementing-state TRNs for Saudi Arabia, Bahrain and Oman follow each country’s own format, and the UAE FTA keeps no public lookup for them, so you verify with the supplier directly. And where goods come in through Dubai Customs, your TRN is linked to your Customs Code on the Dubai Trade or FCA portal; the customs declarations transmitted to the FTA pre-populate Box 6 (imports subject to reverse charge) on your VAT-201. Confirm that linkage on Dubai Trade once a year.

When a TRN problem becomes an FTA problem, and how we help

Most TRN problems resolve inside the buyer–supplier relationship. A smaller number escalate into FTA queries, voluntary disclosures (Form 211) or audits. Common triggers:

• Input VAT recovered on invoices later flagged as bearing invalid TRNs
• Output VAT issued under a TRN that has since been deregistered
• Free-zone TRN suspended because of unfiled returns
• A tax-group dissolution mid-year that orphans previously valid TRNs

If you’re sitting on a stack of supplier invoices nobody has verified, the cleanest first step is a TRN audit across the last 6–12 months of AP records. Most SMEs we onboard find 2–5% of supplier invoices carry a TRN issue — a typo, a deregistered TRN, a TRN belonging to a parent group but issued under a member name, or no TRN at all. It’s almost never zero.

The audit costs about a workday. Skipping it costs whatever the FTA disallows at your next inspection, and the FTA can generally look back five years — longer in cases such as suspected tax evasion.

Velmont Crest VAT services in Dubai include supplier TRN verification as part of monthly input-VAT reconciliation. We don’t charge per invoice — it’s part of the standard retainer. If you’ve already had a query letter, we also handle voluntary disclosures and supplier-side TRN cleanup as one engagement. For related reading, see how TRN checks fit into VAT return filing in the UAE and the reverse charge mechanism UAE guide, where foreign-supplier TRN treatment matters most.

Build the check into the documents, not just the process

The most durable fix for TRN risk isn’t a policy memo — it’s making verification structurally impossible to skip at the two moments a TRN enters your records.

At invoice creation. Your own TRN and, for full tax invoices, the buyer’s TRN are mandatory Article 59 fields. If the template forces the field, the check happens; if the field is free-text, typos ship. Our free UAE tax invoice generator lays out every mandatory field — including both TRN positions — so you can benchmark your current template against the required format in a couple of minutes.

At supplier onboarding. Add one line to the vendor-master form: TRN verified on FTA portal, date, screenshot attached. That single control converts a future audit argument into a filed piece of evidence. Where it’s missing, unverified TRNs surface later as disallowed input VAT — one of the five most frequent findings in an FTA tax audit, and each disallowed claim feeds the incorrect-return penalty base explained in our VAT penalties in UAE guide.

Two habits complete the loop. Re-verify before any unusually large payment, because registrations get suspended mid-relationship. And sweep the active vendor master quarterly — a one-hour task that catches status changes before they contaminate a filed return, rather than after.

FAQs

What is VAT verification in the UAE? VAT verification is checking a supplier’s or your own 15-digit TRN on the FTA’s public lookup at tax.gov.ae. Because the UAE VAT number and the TRN are the same number, that one panel is the whole of it — free, no login, name and status returned. Screenshot the result and date it.

Where can I check a UAE TRN for free? The FTA EmaraTax portal at tax.gov.ae. The verification lookup is public, no login needed.

Can I claim input VAT without verifying the supplier’s TRN? Legally yes — the obligation is to hold a valid tax invoice. Practically no. If the TRN turns out invalid or deregistered during an audit, the input VAT is disallowed and you’re the one out of pocket. Verify before you pay.

What if my supplier’s TRN starts with something other than 100? Then it isn’t a valid UAE VAT TRN. Don’t pay the VAT element. Ask the supplier for a corrected invoice carrying their actual FTA-issued TRN.

How long is a UAE TRN valid? There’s no expiry. It stays valid until you deregister voluntarily, or the FTA suspends or deregisters it. Re-check high-value suppliers from time to time anyway.

Is the TRN the same as the trade licence number? No. The trade licence number comes from the licensing authority (DED, or the free zone) and marks you as a legal entity. The TRN comes from the FTA and marks you for VAT. Two different numbers entirely.

Do free-zone companies have TRNs? If they’re VAT-registered, yes. Even Qualifying Free Zone Persons (QFZPs) under corporate tax often carry a VAT TRN. Verify them the same way as anyone else.

What’s the penalty for using someone else’s TRN? Issuing tax invoices under a TRN that isn’t yours is treated as tax evasion under the UAE Tax Procedures Law (Federal Decree-Law No. 28 of 2022) — which can carry penalties of several times the evaded tax plus potential prosecution. Not a grey area.

Can I deregister my UAE TRN if I stop trading? Yes. File a VAT deregistration via EmaraTax within 20 business days of stopping taxable supplies, or once your turnover sits below the voluntary registration threshold (AED 187,500) for 12 consecutive months. Miss that window and the FTA charges a late-deregistration penalty of AED 1,000 for each month (or part of a month) of delay, up to a maximum of AED 10,000.
