A TRN number in the UAE is a 15-digit Tax Registration Number issued by the Federal Tax Authority to businesses registered for VAT. It confirms that a company is legally permitted to charge VAT and file VAT returns. This guide explains who must register, the required documents, and how to obtain your TRN.
What is a TRN Number in the UAE?
A TRN is the official identifier assigned by the FTA when a business registers for VAT. It confirms the company’s tax status and links all VAT filings and payments to that entity.
A TRN is always 15 digits long and contains only numbers. For example:
Sample TRN: 100234567890123
This sequence is illustrative only, but it reflects the exact format you will see on a VAT Registration Certificate.
Without a TRN, a company cannot lawfully collect VAT or claim input tax credits.
TRN vs TIN in the UAE
Many businesses confuse the Tax Registration Number (TRN), which applies to VAT, with the broader Tax Identification Number (TIN) used for other taxes. The table below shows the key differences:
| Feature | TRN (Tax Registration Number) | TIN (Tax Identification Number) |
|---|---|---|
| Purpose | VAT identifier used on invoices, returns, and imports/exports | General identifier for all federal taxes, including Corporate Tax and Excise |
| Issued by | Federal Tax Authority (FTA) upon VAT registration | FTA or Ministry of Finance depending on the tax type |
| Format | Always a 15-digit numeric code | Format varies by tax regime |
| Use cases | Charging VAT, filing VAT returns, reclaiming input VAT | Corporate Tax registration and filings, excise obligations, other taxes |
| Example | 100234567890123 (illustrative VAT TRN) | Separate Corporate Tax TIN issued by MoF |
Corporate Tax TIN in the UAE
With the introduction of Corporate Tax on 1 June 2023, businesses may now receive a separate Corporate Tax TIN in addition to their VAT TRN. This TIN is issued by the Ministry of Finance through the FTA’s EmaraTax system and is used only for corporate tax filings.
Companies must therefore manage two different tax numbers: one for VAT (the TRN) and one for Corporate Tax (the TIN). Each must appear on the relevant returns and compliance documents.
For practical guidance on this process, see our Corporate Tax Registration UAE page.
Why a TRN Matters for UAE Businesses
Having a TRN is more than just compliance. It ensures your business can:
- Legally charge VAT on taxable supplies
- File VAT returns and claim input tax credits
- Issue compliant tax invoices with supplier and customer TRNs
- Build credibility with clients and partners
- Link VAT registration with UAE Customs for imports and exports
- Reclaim input VAT on business expenses
Example: A consultancy earns AED 420,000 in a year. By law, it must register for VAT and obtain a TRN. If it delays, it risks a fine of AED 10,000. More importantly, without a TRN it cannot reclaim input VAT on office rent and supplier invoices, costing the business thousands in unrecoverable VAT every quarter.
Operating without a TRN when registration is required can result in fines such as AED 10,000 for late VAT registration.
Who Needs a TRN Number in the UAE?
- Mandatory registration: If annual taxable supplies or imports exceed AED 375,000, you must register for VAT.
- Voluntary registration: If taxable supplies or expenses exceed AED 187,500, you may opt to register.
- Zero-rated exception: A business making only zero-rated supplies can apply for an exception from VAT registration under Article 16 of the Executive Regulations. If approved, no TRN is issued and input VAT cannot be claimed. If standard-rated supplies begin, registration becomes mandatory.
- Non-residents: Foreign businesses making taxable supplies in the UAE must register regardless of turnover.
- Freelancers & individuals: If revenues cross the thresholds, registration is required.
How to Apply for a TRN in the UAE
Register for VAT and receive your TRN via the FTA’s EmaraTax portal:
1. Create an account: Sign up on tax.gov.ae with your email and business details.
2. Start VAT application: Log in and select VAT registration in EmaraTax.
3. Fill in details: Enter legal name, trade license, nature of business, and turnover.
4. Upload documents: Provide trade license, Emirates ID, passport copies, address proof, bank details, and financial records.
5. Submit application: Review and send to the FTA for approval.
6. Receive TRN: Once approved, download the VAT Registration Certificate showing your TRN.
Tip: Check your GIBAN
Alongside your TRN, your EmaraTax dashboard will also show a GIBAN (Generated IBAN). This is a unique bank account number issued by the FTA for each VAT registrant. It is used only for VAT payments through UAE banks and exchange houses. Always generate a payment reference in EmaraTax before using your GIBAN to ensure the payment is credited correctly.
How to Verify a TRN Number in the UAE
The FTA provides free tools to confirm a TRN’s validity:
- FTA website: Use the TRN verification function on tax.gov.ae. Enter the 15-digit TRN to see the legal name of the entity.
- EmaraTax app: Verify TRNs via the FTA’s official mobile application.
- FTA support: Contact FTA customer care if the online service is unavailable.
Verification helps prevent VAT fraud and ensures VAT is only paid to genuine registrants. For more information on how to verify a TRN, see this blog “TRN Verification in the UAE”.
Using the TRN Correctly
Your TRN must appear on:
- All tax invoices issued by your business
- VAT returns and FTA correspondence
- Customs documentation for imports and exports
- Contracts and purchase orders where VAT is charged
Invoice rules: The FTA requires tax invoices to display your TRN and to be issued within 14 calendar days of each taxable supply. Use the FTA’s invoice checklist to ensure compliance.
Return deadlines: VAT returns must be filed and paid within 28 days after the end of your tax period via EmaraTax.
Tax groups: If you register as a VAT Tax Group, the group operates under one TRN, held by the representative member, and that TRN must be used for all external supplies.
Common Issues with TRN Numbers
- Invalid TRN on invoice: May indicate the supplier is not properly registered
- Delayed registration: Leads to penalties and VAT liability
- Outdated details: Must be updated promptly in EmaraTax
- TRN misuse: Report unauthorized use immediately to the FTA

Frequently Asked Questions
Is TRN the same as TIN?
No. TRN applies to VAT, while TIN is broader and includes Corporate Tax. A business can hold both.
Can one company have multiple TRNs?
Only if part of a VAT Tax Group. Otherwise, each entity has a single TRN.
What if I lose my TRN certificate?
You can download a copy anytime from your EmaraTax dashboard.
Do e-commerce businesses need a TRN?
Yes. Online sellers must register once taxable supplies exceed AED 375,000.
How long is a TRN valid?
It remains valid until you deregister with the FTA.
What is a GIBAN and why is it linked to my TRN?
A GIBAN (Generated International Bank Account Number) is a unique bank account number issued by the FTA for each VAT registrant. It is used only for VAT payments through UAE banks and exchange houses. Your TRN is tied to your GIBAN, and you must generate a payment reference in EmaraTax before using it to ensure the payment is credited to the correct tax account.
