You can verify any UAE Tax Registration Number (TRN) free of charge on the Federal Tax Authority's website: open the TRN verification tool on tax.gov.ae, enter the 15-digit number, complete the security check, and the FTA displays the registered business name the TRN belongs to. If nothing comes back — or the name doesn't match the invoice — do not pay the VAT line on that invoice.
How to verify a TRN — 4 steps
Go to the FTA website — tax.gov.ae — and open the TRN verification tool (available directly on the site without any login, and also inside EmaraTax).
Enter the 15-digit TRN exactly as shown on the invoice or quotation.
Complete the captcha/security check and submit.
Read the result: a valid TRN returns the registrant's legal name (English and Arabic). Confirm it matches the supplier name on your invoice — a valid TRN belonging to a different company is still a red flag.
What a TRN is and where it appears
The TRN is the unique 15-digit number the FTA issues on VAT registration. Every registered business must show it on its tax invoices, tax credit notes and VAT-related documents. On a compliant invoice you'll find it alongside the supplier's name and address in the header — if an invoice charges 5% VAT but shows no TRN at all, it is not a valid tax invoice.
TRN: 100 2345 6789 0003
| Office supplies (excl. VAT) | AED 4,000.00 |
| VAT @ 5% | AED 200.00 |
| Total | AED 4,200.00 |
Why verifying matters
- Your input VAT depends on it. You can only recover input VAT on the strength of a valid tax invoice from a registered supplier. If the TRN is fake or belongs to someone else, the FTA can disallow your recovery in an audit — the cost lands on you, not the fraudster.
- Charging VAT without registration is a real scam. Unregistered businesses sometimes add "VAT" to invoices and pocket the 5%. Verification is the 30-second defence.
- Onboarding hygiene. Verify every new supplier's TRN once at onboarding and keep a dated screenshot in the vendor file — with e-invoicing arriving in 2027, clean TRN master data stops being optional anyway: structured invoices with wrong TRNs will simply fail validation.
Key takeaway
Verify once at onboarding, re-verify when anything changes (name, licence, bank details), and never process an invoice whose TRN doesn't return the supplier's exact legal name.
If a TRN doesn't check out
Don't pay that VAT line
- Ask the supplier for their VAT registration certificate — typos happen; a genuine supplier resolves this in minutes.
- If they can't produce one, don't pay the VAT element and don't claim it.
- Businesses knowingly charging VAT without registration can be reported to the FTA through its official channels.

How do I verify a TRN in the UAE?
Use the free TRN verification tool on the FTA website (tax.gov.ae): enter the 15-digit TRN, pass the security check, and the registered business name is displayed. No login is required.
How many digits is a UAE TRN?
15 digits. Anything shorter or longer is not a valid UAE TRN.
Is TRN verification free?
Yes — the FTA's tool is free and publicly available, with no account needed.
What if an invoice charges VAT but has no TRN?
It isn't a valid tax invoice. Don't pay the VAT element, and don't claim input VAT on it — request a compliant invoice showing the supplier's TRN.
Can I claim input VAT if the supplier's TRN turns out to be invalid?
No — recovery requires a valid tax invoice from a registered supplier. Invalid-TRN invoices are among the first disallowances in FTA audits, which is why verification at onboarding matters.
Is the TRN the same as a trade licence number?
No. The trade licence number comes from the licensing authority; the TRN is issued separately by the FTA on VAT registration. A business quoting only a licence number is not demonstrating VAT registration.
How do I find my own company's TRN?
It's on your VAT registration certificate and in your EmaraTax account dashboard.
