UAE TRN Validator
Verify UAE Tax Registration Numbers (TRN) format instantly. Free validation tool to check if your TRN follows FTA guidelines.
About TRN Format
A valid UAE TRN is a 15-digit number starting with '100'. This tool validates the format only. For official verification, please check with the FTA portal.
What is a Tax Registration Number (TRN)?
A Tax Registration Number (TRN) is a unique 15-digit identifier issued by the UAE Federal Tax Authority (FTA) to businesses and individuals registered for tax purposes in the United Arab Emirates. This number is essential for all tax-related transactions and compliance activities.
The TRN serves as your business's official tax identification and must be displayed on all tax invoices, VAT returns, and official correspondence with the FTA. It's similar to a business license number but specifically for tax purposes.
Why is TRN Important?
Legal Compliance
Required by UAE law for all VAT-registered businesses to conduct taxable activities.
Tax Invoice Validation
Must be displayed on all tax invoices to claim input VAT and issue valid invoices.
FTA Communication
Used for all official communication with the Federal Tax Authority.
Business Credibility
Demonstrates your business is officially registered and compliant with UAE tax laws.
Understanding TRN Format
The UAE Tax Registration Number follows a specific 15-digit format that's standardized across all registrations.

Who Needs a Tax Registration Number?
Not all businesses in the UAE are required to obtain a TRN. Here's who needs to register:
Mandatory Registration
Businesses Exceeding Mandatory Threshold

Corporate Tax Registration
All mainland businesses and free zone companies subject to UAE Corporate Tax must obtain a TRN for corporate tax purposes.
Excise Tax Registrants
Businesses involved in producing, importing, or storing excise goods (tobacco, energy drinks, carbonated drinks, sweetened drinks) must register.
Voluntary Registration
Businesses Above Voluntary Threshold
If your annual taxable supplies and imports are between AED 187,500 and AED 375,000, you can choose to register voluntarily.
Businesses Incurring Recoverable VAT
If you incur significant VAT on expenses that could be recovered, voluntary registration may be beneficial even below the threshold.

Learn About VAT ComplianceFrequently Asked Questions
Can I use the same TRN for VAT and Corporate Tax?
Yes, the FTA issues a single TRN that can be used for all tax types (VAT, Corporate Tax, Excise Tax). You don't need separate TRNs for different taxes.
What happens if I don't register when required?
Failure to register for tax when required can result in penalties ranging from AED 10,000 to AED 20,000. It's important to register within the required timeframe.
Can I verify someone else's TRN?
Yes, the FTA provides a TRN verification service on their website where you can check if a TRN is valid and active. This is useful when dealing with suppliers and customers.
How long does a TRN remain valid?
A TRN remains valid as long as your business is registered for tax. If you deregister or your business closes, the TRN will be deactivated.
What should I do if I lose my TRN?
You can retrieve your TRN by logging into your EmaraTax account. It's displayed on your tax registration certificate, which you can download from the portal.
Do free zone companies need a TRN?
It depends. Free zone companies need a TRN if they conduct business in mainland UAE, import goods into the UAE mainland, or are subject to Corporate Tax. Qualifying free zone persons may be exempt from Corporate Tax but might still need a TRN for other taxes.
