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.
(starts with 1)
(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.
