Transacting with an unregistered or deregistered entity can trigger FTA penalties and disallow your entire VAT recovery on that invoice. For a single large purchase, that could mean tens of thousands of dirhams lost.
What Is a TRN (Tax Registration Number) in the UAE?
A Tax Registration Number (TRN) is a unique 15-digit identifier issued by the Federal Tax Authority (FTA) to every business or individual that registers for VAT, corporate tax, or excise tax in the UAE. It is the primary reference number for all UAE tax matters.
A common mistake among new business owners: confusing the TRN with a trade licence number or commercial registration number or corporate tax registration number. These are entirely different identifiers. Your trade licence is issued by the Department of Economic Development or a free zone authority. Your TRN comes from the FTA.
The TRN format is consistent. It is always 15 digits, starts with “100”, and contains no letters or special characters.
Since the introduction of UAE corporate tax in June 2023, the TRN landscape has expanded. Businesses now receive TRNs for corporate tax registration as well. A single entity typically holds one TRN that covers both VAT registration and corporate tax, though the registration status may differ per tax type.
| Attribute | Detail |
| Issued by | Federal Tax Authority (FTA) |
| Length | 15 digits |
| Starts with | 100 |
| Applies to | VAT, Corporate Tax, Excise Tax |
| NOT the same as | Trade Licence Number, Commercial Registration |
Tip: If someone gives you a TRN that is shorter than 15 digits or contains letters, it is not a valid UAE TRN.
Why TRN Verification Matters for UAE Businesses
TRN verification isn’t optional housekeeping. It directly protects your money, your compliance record, and your business relationships. Three core reasons:
1. VAT compliance
Businesses can only claim input VAT on invoices from legitimately VAT-registered suppliers. If a supplier’s TRN is invalid or deregistered, the FTA will disallow your input VAT claim during an audit. For companies processing significant purchase volumes, the disallowed amounts add up fast.
2. Fraud prevention
Fake TRNs on invoices are a documented issue in the UAE market. Verifying every supplier TRN before processing payment is basic due diligence. It protects your business from fraudulent transactions and ensures you’re dealing with a real, registered entity.
3. Avoiding FTA penalties
The FTA imposes administrative penalties under Cabinet Decision No. 49 of 2021 (amending Cabinet Decision No. 40 of 2017) for non-compliance. Penalties for tax invoice errors can reach AED 5,000 per invoice for the first offence and AED 10,000 for repeats. Other VAT-related violations carry their own specific amounts under the published schedule — most range from a few hundred dirhams up to AED 50,000 per article breached, depending on the violation type and frequency.
Staying updated with the latest FTA regulations is essential to avoid administrative fines and VAT-related penalties. Read our latest guide on FTA updates and how to avoid tax penalties in the UAE.

A real anonymised mini-case (BCL Globiz experience)
Last quarter we ran a TRN sweep on a Jebel Ali trading client’s vendor list (about 80 suppliers) and found two TRNs that had been deregistered mid-year. The client had reclaimed AED 18,200 of input VAT on invoices issued after deregistration. Catching this in the next return saved the same amount in disallowed credit and avoided AED 5,000 in invoice-error penalties.
This is why we build TRN verification into every client’s monthly compliance workflow — catching issues before they become penalties.
How to Verify a TRN on the FTA Portal (Step-by-Step)
This is the core process. The shortcut: open https://tax.gov.ae/en/Search.aspx, enter the 15-digit TRN, and click Search. No login required.
Step 1 — Go to the FTA TRN Verification Page
Open https://tax.gov.ae/en/Search.aspx in your browser. No FTA account or login is required for basic TRN verification — it is a free, public tool. The page is available in both English and Arabic; use the language toggle in the top-right corner.
Step 2 — Enter the TRN in the Search Field
Type or paste the 15-digit TRN into the search field. Enter only the digits — no spaces, dashes, or prefixes.
If you’re copying from a PDF invoice, be careful. PDFs sometimes include hidden characters or extra spaces that break the search. If copy-paste doesn’t return results, type the 15 digits manually.
You can also search by the tax registrant’s name (covered in the next section).
Step 3 — Review the Verification Results
Click “Search”. The FTA portal returns the registrant’s name, TRN, and registration status. Here’s how to interpret each result:
| Result | What it means | What to do |
| Active | Entity is VAT/CT registered and in good standing | Safe to transact; retain a screenshot for your records |
| Deregistered | The entity was registered but is no longer active | Do NOT accept VAT invoices dated after deregistration; contact the supplier |
| No results found | TRN does not exist in the FTA system | Do NOT transact; request a valid TRN or report to the FTA |
How to Verify a TRN by Company Name
Sometimes you have a supplier’s company name but not their TRN number. The FTA portal handles this too.
On the same FTA verification page, switch the search type from “TRN” to “Name” using the dropdown or toggle. Enter the company name as it appears on the trade licence — not a shortened or trading name.
The name must match the FTA registration exactly. Partial matches may not return results. If your first search fails, try variations: “ABC Trading LLC” vs. “ABC Trading L.L.C.” vs. the full legal name.
TRN for VAT vs. Corporate Tax vs. Excise Tax — What’s the Difference?
The UAE tax landscape has expanded significantly since corporate tax took effect in June 2023, with first full filing cycles now underway. Previously, TRN was associated almost exclusively with VAT. Now, businesses may hold TRN registrations for multiple tax types.
1. VAT — Mandatory for businesses exceeding AED 375,000 in taxable supplies. Voluntary registration threshold: AED 187,500. Rate: 5%.
2. Corporate tax — Mandatory for all UAE businesses and entities subject to corporate tax. Rate: 9% on taxable income above AED 375,000. 0% on income up to that threshold.
3. Excise tax — Applicable to businesses dealing in excise goods (tobacco, carbonated drinks, energy drinks, sweetened drinks). Rates range from 50% to 100% depending on the product.
| Tax type | Mandatory threshold | Rate | TRN required? |
| VAT | AED 375,000 taxable supplies | 5% | Yes |
| Corporate Tax | All taxable persons | 9% (above AED 375,000 income) | Yes |
| Excise Tax | Excise goods importers/producers | 50%–100% by product | Yes |
As of 2026, the FTA issues one TRN per entity. However, the registration status may differ per tax type. A company might be VAT-registered but not yet corporate-tax-registered. When running TRN verification, check the specific tax registration type — not just whether the TRN exists.
TRN on Invoices — Where to Find It and What to Check
UAE tax law (Federal Decree-Law No. 8 of 2017 on VAT, as amended) requires every tax invoice to include the supplier’s TRN. It typically appears in the invoice header or footer, near the company name and address.
Mandatory elements of a valid UAE tax invoice that relate to TRN:
- Supplier’s TRN
- Buyer’s TRN (if the buyer is VAT-registered)
- The words “Tax Invoice” clearly stated
- Invoice date and sequential invoice number
- Description of goods/services, quantity, unit price
- VAT amount and total
If a TRN is missing from an invoice, request a corrected invoice. You cannot claim input VAT without a valid tax invoice showing the supplier’s TRN. If the TRN on the invoice doesn’t match the FTA verification result, contact the supplier immediately. Do not process the invoice.
Before processing any supplier invoice, verify:
- TRN is present
- TRN is 15 digits
- TRN matches FTA verification
- Supplier name matches FTA record
- Invoice is dated within the supplier’s active registration period
Common TRN Verification Errors and How to Fix Them
The FTA portal is straightforward, but real-world issues come up regularly. The six most common problems and their fixes:
| Problem | Likely cause | Fix |
| “No results found” for a TRN you believe is valid | Typo, pending registration, or wrong tax type | Double-check the number digit by digit; contact the supplier for confirmation |
| TRN shows “Deregistered” | Entity voluntarily or compulsorily deregistered | Do not accept tax invoices dated after deregistration; request updated documentation |
| Name mismatch between the invoice and the FTA result | FTA records the legal entity name, not the trading name | Verify using the trade licence; the legal name and brand name often differ |
| Portal timeout or technical errors | FTA website downtime or slow loading | Try again later; clear browser cache; the FTA portal works best on Chrome |
| Copy-paste errors | Hidden characters from PDFs or Excel files corrupt the TRN | Type the 15 digits manually instead of pasting |
| Newly registered business not appearing | 24–48 hour delay between FTA approval and public system update | Wait and re-check; if still missing after 48 hours, contact the FTA |
The copy-paste issue is more common than you’d expect. PDF invoices frequently embed invisible formatting characters that break the FTA search. Always try manual entry if paste doesn’t work.
For newly registered businesses, the 24–48 hour delay catches many people off guard. If you’ve just received your FTA approval but your TRN check returns nothing, give it time.
FAQs
How can I verify my TRN number in the UAE?
Go to the FTA portal at https://tax.gov.ae/en/Search.aspx. No login is required. Enter the 15-digit TRN in the search field, click Search, and the portal returns the registrant’s name and registration status. You can also search by company name using the name toggle on the same page.
Where can I see my VAT TRN?
The VAT TRN will be available on the VAT registration certificate. It starts with 100. Whereas the trade license number is generally short and not 15 digits. Corporate Tax Registration number is entirely different and not to be confused with VAT TRN.
What is a TRN number in the UAE?
A TRN is a 15-digit Tax Registration Number issued by the FTA to businesses registered for VAT, corporate tax, or excise tax. It always starts with “100” and contains only digits. It is required on all UAE tax invoices and is not the same as a trade licence number.
Can I verify a TRN by company name instead of the number?
Yes. The FTA portal allows searching by the registered entity name. Use the exact legal name from the company’s trade licence — partial or trading names may not return results. If the first search fails, try variations like “LLC” vs. “L.L.C.” vs. the full legal name.
What does it mean if a TRN shows “deregistered”?
“Deregistered” means the entity was previously registered but has since cancelled its tax registration — either voluntarily or by FTA action. Invoices dated after the deregistration date should not carry this TRN, and you cannot claim input VAT on such invoices. Contact the supplier for updated documentation.
How long does it take for a new TRN to appear in the FTA system?
There is typically a delay of 24–48 hours between FTA approval of a tax registration and the TRN appearing in the public verification system. If your TRN still doesn’t appear after 48 hours, contact the FTA at 600 599 994 or email taxpayerservices@tax.gov.ae.
