UAE TRN registration and verification
A Tax Registration Number is how the FTA identifies a taxable person, and it is the single field on an invoice most likely to cost somebody money — because a customer cannot claim input credit against a tax invoice carrying a wrong or absent TRN.
- Your TRN
- On every tax invoice and credit note you issue
- Customer TRN
- Where they are registered and claiming credit
- Supplier TRN
- On bills you claim input credit against
- Format
- 15 digits, issued by the FTA
What you need to know
What a TRN is
A fifteen-digit number issued by the Federal Tax Authority identifying a registered taxable person. It is not a trade licence number and the two are frequently confused.
When registration is required
Mandatorily once taxable supplies cross the mandatory threshold over the rolling measurement period; voluntarily above a lower one, which is often worth doing to recover input tax.
Tax groups
Related entities under common control can register as a single tax group with one TRN, so supplies between them fall outside VAT.
Why verification matters
Your customer’s credit depends on the TRN on your invoice being right. A typo discovered during an audit is a problem for them and a conversation for you.
Verify before relying
The FTA provides a verification facility. Checking a new counterparty’s TRN once, when you set them up, is cheap insurance.
Displaying it
A registrant is generally expected to display the TRN on tax invoices and related documents.
How to handle TRNs properly
- Capture it at party setup. Not at invoice time, when somebody is in a hurry and will type it from memory.
- Validate the format. Fifteen digits. A format check catches most transcription errors immediately.
- Verify the registration. Through the FTA facility for new or significant counterparties.
- Print it on the document. Yours always, theirs where they are registered.
TRN questions
What is a TRN?
A Tax Registration Number — a fifteen-digit identifier issued by the UAE Federal Tax Authority to a registered taxable person. It is distinct from a trade licence number, which is issued by a different authority for a different purpose.
Why does my customer’s TRN matter to me?
Because their entitlement to input credit depends on holding a valid tax invoice with the right details. If the TRN on your invoice is wrong, their credit can be challenged, and the resulting conversation is yours to have.
Can I check whether a TRN is genuine?
The FTA provides a verification facility. tBiz validates the format when you save a party, which catches transcription errors; confirming the registration itself is a separate check worth doing for new counterparties.
Is this page tax advice?
No. Registration thresholds and requirements change. Confirm with a UAE tax adviser.
