TRN Verification in the UAE (2026): The New Rules and How to Verify a TRN Correctly

For years, verifying a supplier’s Tax Registration Number in the UAE was good practice but rarely urgent. That changes on 1 October 2026. A new Federal Tax Authority decision turns supplier verification into a legal condition for reclaiming your input VAT, and a valid tax invoice on its own will no longer protect your claim.

This guide covers what a TRN is, how to verify one properly, and, most importantly, what FTA Decision No. 13 of 2026 now requires of every VAT-registered business.

What a TRN is, in one minute

A Tax Registration Number (TRN) is a unique 15-digit number the Federal Tax Authority issues to every business or individual registered for VAT. It arrived with the UAE’s 5 percent VAT on 1 January 2018, and since 2023 it doubles as the identifier for Corporate Tax. In effect, it is the single tax identity of a UAE business.

A few facts worth fixing in your head:

A valid TRN is exactly 15 digits, with no letters, spaces or dashes.
Many begin with 1, and often with 100, but the prefix alone proves nothing. A well-formatted number can still be unregistered or belong to another company.
The TRN must appear on every tax invoice, credit note and VAT return. If a supplier charges you VAT, their TRN is legally required to be on the invoice.

That last point is the whole reason verification matters: the TRN is your evidence that the party charging you VAT is entitled to.

How to verify a TRN on the FTA portal

The official check is free, takes under a minute, and needs no login or UAEPass account.

Check the format first. Rule out typos and wrong-length numbers before anything else. You can use our free ++TRN validator++ to do this instantly.
Open the FTA verification tool at eservices.tax.gov.ae and select the TRN Verification service.
Enter the 15-digit TRN exactly as printed on the invoice or certificate. Copy and paste it if you can; one wrong digit gives a misleading result.
Complete the captcha.
Read the returned legal name in English and Arabic, and the registration status.

Then apply the only rule that matters: the name has to match. A valid number attached to a name that does not match your supplier is a red flag, not a green light. Pause the payment and reconcile before you proceed. If the number returns nothing, do not pay the VAT.

A quick word on third-party “TRN checker” sites: they are useful for a first-pass format check and for building the habit into your workflow, but only the FTA’s own lookup is authoritative for the legal name and status. Confirm there.

What changed: FTA Decision No. 13 of 2026

Here is the part most guides have not caught up with yet.
On 22 July 2026, the Federal Tax Authority issued Decision No. 13 of 2026, effective 1 October 2026. It puts flesh on Article 54(bis) of the VAT Law, a provision inserted by Federal Decree-Law No. 16 of 2025. Together they hand the FTA the power to deny your input VAT recovery when a supply is connected, anywhere in the chain, to tax evasion.

The mechanics matter:

If you actually knew of the connection to evasion, refusal of your input VAT claim is mandatory.
If you should have known, based on the circumstances, refusal is discretionary.
Crucially, you are deemed to have been required to know if you failed to verify the validity and integrity of the supplies you received, in line with the measures the FTA now prescribes.

In other words, “I had a valid invoice” is no longer a defence. From 1 October 2026, you have to be able to show you did the checks.

The two levels of checks you now have to run

Decision No. 13 sets obligations at two levels. Both need to be documented.

1. Supplier verification

Carried out the first time you deal with a supplier, and repeated if 12 months have passed. It requires you to:

Check identity documentation against official databases. This is where TRN verification lives. Confirming the supplier’s TRN and matching legal name is the core identity check.
Verify the individual authorised to represent the supplier.
Confirm the supplier has an actual place of business consistent with its claimed activity.

You also have to assess three prescribed risk indicators: changes of address, changes of key personnel, and transactions that are disproportionate to the size and history of the business.

Where your annual purchases from a single supplier exceed AED 375,000, there are two extra steps: obtain unqualified written confirmation from a UAE-authorised bank that the supplier holds an account there, and review public information and media coverage of the supplier.

2. Supply verification

This is the heavier obligation, because it applies to every individual supply you receive, not just to onboarding a supplier. For each one, you need to be satisfied that:

The supplier’s participation rests on genuine commercial reasons.
Pricing and margins are not commercially unjustifiable.
The goods or services fall within the supplier’s licensed activities.
The title and origin of the goods are sound.
Where an intermediary is involved, its role is commercially explicable.
Payment is electronic. Any cash payment needs a documented commercial reason.

A written policy is mandatory

Article 5 of the decision requires a written policy setting out who performs, reviews and supervises these checks. This is not an internal nicety; it is a compliance document the FTA can ask to see.

The one exemption, and why it barely helps

There is a de minimis exemption under Article 6 for supplies below AED 10,000 excluding VAT. It sounds generous until you read the condition: it is switched off entirely once total supplies from a given supplier exceed AED 100,000 over the preceding 12 months, or are expected to exceed that over the following 12 months.

That threshold works out to roughly AED 8,300 a month with one supplier, a level most recurring vendor relationships cross without any red flag at all. For any supplier you use regularly, assume the exemption does not apply to you.

What this means in practice

Strip away the legal language and the message to UAE businesses is simple:

Verify every supplier’s TRN and legal name before you onboard them, and re-verify at least once a year.
Keep the evidence. Screenshots, records of the check, the date, and who ran it. If you cannot show it, you did not do it.
Watch the risk indicators and pay electronically.
Write the policy down and name who is responsible.
Do not lean on the AED 10,000 exemption for any supplier you use more than occasionally.

With just weeks between the decision and the deadline, the practical question is not whether to verify, but how to do it across every supplier and every invoice without drowning your finance team in manual checks.

Making verification part of the workflow

One-off TRN checks are easy. The new regime is not about one-off checks; it is about doing them consistently, at scale, and being able to prove it a year later during an audit.

Naqood is an FTA-accredited cloud accounting and e-invoicing platform built for UAE businesses. It keeps supplier TRNs stored against their verified legal names, flags mismatches at the point of invoice entry, and maintains the documented trail that Decision No. 13 now requires, so supplier verification runs inside your day-to-day accounting rather than as a scramble before every payment.

Frequently asked questions

When do the new TRN verification rules take effect? FTA Decision No. 13 of 2026 takes effect on 1 October 2026. It was issued on 22 July 2026.

Does a valid tax invoice still protect my input VAT claim? Not on its own. From 1 October 2026, you must also be able to show you verified the supplier and the supply. If a transaction is linked to tax evasion and you did not run the required checks, the FTA can deny your input VAT recovery.

How often do I have to re-verify a supplier? At least every 12 months, and again whenever a risk indicator appears, such as a change of address or key personnel.

What is the AED 375,000 threshold? Where your annual purchases from a single supplier exceed AED 375,000, you must also obtain written confirmation from a UAE-authorised bank that the supplier holds an account there, and review public and media information about them.

Is there any exemption for small purchases? There is a de minimis exemption for supplies below AED 10,000 excluding VAT, but it no longer applies once total supplies from that supplier pass AED 100,000 over 12 months. For most recurring suppliers, it will not help.

How do I actually verify a TRN? Check the format, then confirm the registered legal name and status on the official FTA tool at eservices.tax.gov.ae. Match the returned name to the supplier and their trade licence before you pay.
