A Tax Registration Number, or TRN, is the 15-digit identifier the Federal Tax Authority issues to every business registered for VAT in the UAE. Before signing a contract, processing a supplier invoice, or claiming input VAT recovery, checking that a company’s TRN is real and active is a five-minute task that protects against fraudulent invoices and rejected VAT claims later. This guide covers where to find a TRN, how to verify one through the FTA’s official portal, and the mistakes that most often lead businesses to accept an invalid TRN without realizing it.
What a TRN Number Is and Why It Matters
A TRN is a unique 15-digit number issued by the Federal Tax Authority (FTA) to every business registered for VAT, following a format such as 100012345600003. It functions as a company’s tax identity, used to track VAT transactions, verify submissions, and maintain accountability across the national tax system. Under Federal Decree-Law No. 8 of 2017 on VAT, every VAT-registered business must display its TRN on all tax invoices, VAT credit notes, and other VAT-related documentation.
| Reason it matters | Explanation |
|---|---|
| Business legitimacy | Confirms the company is officially registered with the FTA |
| VAT compliance | Only businesses with a valid TRN can legally charge VAT |
| Input tax recovery | Buyers can only reclaim VAT on purchases from TRN-registered suppliers |
| Business transparency | Builds trust with clients, suppliers, and government bodies |
How to Find a Company’s TRN Number in the UAE
There are three practical places to look before turning to formal verification:
- The company’s tax invoice. Every VAT-registered business must display its TRN on issued tax invoices, usually labelled “TRN” or “Tax Registration Number.” A valid TRN always has exactly 15 digits, so a number that’s shorter or longer is a red flag before you even verify it.
- Other official documents. Business contracts, formal quotations, and sometimes the company’s website footer or “About Us” page list a TRN.
- Directly from the company. A legitimate VAT-registered business is expected to provide its TRN on request when it relates to a VAT transaction.

How to Verify a TRN Through the FTA Portal
The only government-endorsed way to confirm a TRN is genuine is the FTA’s TRN Verification service at tax.gov.ae. This is the step that actually matters for compliance, since a number that looks like a valid TRN format is not proof that it belongs to a real, active VAT registration.
- Go to tax.gov.ae
- Navigate to the TRN Verification service under the Services section
- Enter the 15-digit TRN
- Submit, the registered legal name of the business appears if the TRN is valid
A successful check confirms three things: the registered legal name of the business, that it is an active VAT-registered entity, and that the TRN has not been revoked. It does not display the company’s address or trade license number, only VAT registration status.
As a worked example: a supplier sends an invoice showing TRN 100012345600003. Before processing payment or claiming input VAT, the buyer enters that number into the FTA portal. If the portal returns a legal name that does not match the name on the invoice, or returns no result at all, that invoice cannot be relied on to support an input VAT claim, regardless of how legitimate the paperwork otherwise looks.

What to Do If a TRN Doesn’t Verify
A TRN that returns no result, or returns a legal name that doesn’t match the supplier on the invoice, needs to be treated as a compliance problem before the transaction proceeds, not after.
- Ask the supplier directly. The business may have simply mistyped the number on the invoice, in which case a corrected invoice resolves it.
- Check whether the business is below the registration threshold. Not every business needs a TRN. Suppliers below AED 375,000 in annual taxable supplies are not required to register, and one below AED 187,500 may not be registered at all, so a missing TRN isn’t automatically a red flag on its own, it depends on the supplier’s scale.
- Do not claim input VAT against an unverified TRN. An invoice with an invalid or unmatched TRN will not support a VAT recovery claim if challenged during an FTA audit.
- Treat a revoked TRN as current. A business that was VAT-registered in the past can have its TRN cancelled through deregistration, so an old invoice with what used to be a valid number is not proof of current registration.
Who Needs a TRN Number in the UAE
Not every UAE business holds a TRN. A business must register, and is issued a TRN, once taxable supplies and imports exceed AED 375,000 in a 12-month period. Voluntary registration, and a TRN along with it, is available from AED 187,500. Sole proprietors, freelancers, and small businesses below the voluntary threshold typically have no TRN at all, which is expected and not itself a compliance issue.

TRN Number Versus Corporate Tax Registration Number
Businesses frequently confuse the VAT TRN with the separate Corporate Tax Registration Number.
| TRN (VAT) | Corporate Tax Registration Number | |
|---|---|---|
| Purpose | VAT registration and transactions | Corporate Tax registration |
| Issued by | Federal Tax Authority | Federal Tax Authority |
| Used for | Tax invoices, VAT returns, VAT credit notes | Corporate Tax filings |
| Same number as the other? | No, issued independently | No, issued independently |
Both are issued by the FTA and identify a registered taxable entity, but a business can hold one, both, or neither depending on whether it meets the VAT and Corporate Tax registration conditions separately. A company below the VAT threshold but subject to Corporate Tax will have a Corporate Tax Registration Number with no TRN at all.
Common Mistakes When Finding or Verifying a TRN
| Mistake | Why it’s a problem |
|---|---|
| Assuming every business has a TRN | Only VAT-registered businesses hold one, many UAE businesses legitimately do not |
| Relying on unverified third-party sources | Only the FTA portal or the company itself is a reliable source |
| Using outdated TRN information | TRNs can be revoked or amended following deregistration |
| Accepting an invoice without a visible TRN | A supplier claiming VAT registration but omitting a TRN is a red flag |
| Not verifying before claiming input VAT | Unverified TRNs can result in rejected VAT recovery during an FTA audit |
