UAE TRN Format Checker

Check that a UAE Tax Registration Number (TRN) has 15 digits — and learn what the TIN and suffix parts mean.

What is a UAE TRN?

A Tax Registration Number (TRN) is the 15-digit number the UAE Federal Tax Authority (FTA) issues when a business registers for VAT. It starts with 1 and ends with 03, and its first 10 digits are the business’s Tax Identification Number (TIN) used in e-invoicing — for example 100069993200003 for ADNOC Distribution.

UAE TRN format

15 digits: the 10-digit TIN, then a 5-digit suffix ending in 03.

1000699932 10-digit TIN
(starts with 1)
00003 Suffix
(ends in 03)

Example: 100069993200003 (Abu Dhabi National Oil Company for Distribution — ADNOC Distribution — as shown on its FTA VAT registration certificate).

  • 15 digits: Digits only — remove spaces and hyphens before checking.
  • Starts 1, ends 03: UAE e-invoicing rules require a TRN to start with 1 and end with 03. This checker currently tests the 15-digit length only.
  • Format check only: This checker confirms the format. It does not query the FTA, so it cannot confirm registration or show a company name.
  • Tax groups: A VAT group shares one TRN, so the registered name may be the group’s, not the individual company’s.

Frequently Asked Questions

What is the format of a UAE TRN?

A VAT Tax Registration Number has 15 digits: it starts with 1 and ends with 03 — for example 100069993200003 for ADNOC Distribution. UAE e-invoicing rules reject a TRN that does not follow this pattern.

How do I verify a UAE TRN?

The checker on this page confirms the number has a valid format. To confirm it is registered and see the registered name, use the Federal Tax Authority’s TRN verification service — see our UAE TRN verification guide.

What is the 10-digit TIN in a UAE TRN?

For UAE e-invoicing, the first 10 digits of the TRN are the business’s Tax Identification Number (TIN), which identifies the business on the e-invoicing network.

Why does the TRN check show a different company name?

The number may belong to a VAT tax group. One TRN can cover several group companies — AD Ports’ group registration covers its parent company and ten other group companies — so the name shown can be the group’s rather than the supplier’s.

Must a UAE tax invoice show the TRN?

Yes. A tax invoice must show the supplier’s TRN. A full tax invoice must also show the recipient’s TRN where the recipient is VAT-registered; a simplified tax invoice (allowed for unregistered recipients, or registered recipients for supplies up to AED 10,000) needs only the supplier’s TRN.

Does a UAE TRN have a check digit?

The Federal Tax Authority does not publish one. The often-used sample 100123456700003 fits the pattern but is not a confirmed registration — only the FTA’s verification service confirms a TRN.
