TRN Verification in UAE: How to Check TRN Validity Online

Robins VG

May 4, 2026

TRN (Tax Registration Number) is the identification number given to every person registered under UAE VAT. It is mandatory that only persons having a valid TRN should charge VAT on supplies. In such a scenario, it is helpful for registered businesses to ensure that they receive supplies from a registered person, so that they can recover the input tax on the supply fearlessly.

For unregistered persons and consumers also, it is essential to ensure that only a genuine registered person charges VAT on supplies to them. To assist this, the FTA has given the provision to verify whether the TRN mentioned on an invoice or quoted by a supplier is valid. Any person can use this tool to ensure that the TRN quoted by their supplier is genuine.

Why is it necessary to verify TRN in the UAE?

Verifying a Tax Registration Number (TRN) in the UAE is a critical step for businesses to ensure VAT compliance, accuracy in transactions, and protection against fraud. It helps confirm that the supplier or customer is legitimately registered with the Federal Tax Authority (FTA).

  • Ensure VAT compliance
    Verifying TRNs helps businesses meet regulatory requirements and avoid non-compliance penalties.
  • Prevent fraud and fake invoices
    Confirms the authenticity of trading partners and reduces the risk of dealing with fraudulent entities.
  • Accurate VAT filing
    Ensures correct reporting of input and output VAT, minimizing errors in VAT returns.
  • Eligibility for Input Tax Credit
    Input VAT can only be claimed on invoices issued by valid TRN holders.
  • Avoid financial and legal risks
    Using invalid TRNs can lead to penalties, rejected invoices, and audit issues.
  • Build trust with business partners
    Demonstrates due diligence and enhances credibility in business transactions.

Hence, this tool can be used by all persons in UAE to ensure that they pay VAT only to persons registered under VAT. Previously, only registered users on the FTA website were able to use this tool. However, the FTA has enhanced this tool recently, to ensure that even persons not registered on the FTA website can use this tool to easily verify a TRN.

What to do if TRN verification fails?

If a Tax Registration Number (TRN) fails verification in the UAE, it is important to take immediate steps to avoid compliance risks and potential penalties. A failed verification may indicate incorrect details, an inactive TRN, or possible fraud. Here are the steps to take when TRN verification fails

  • Recheck the TRN details
    Ensure the TRN has been entered correctly without any typographical errors.
  • Confirm with the supplier or customer
    Reach out to the concerned party to verify and obtain the correct TRN details.
  • Request supporting documents
    Ask for a copy of the VAT registration certificate to validate the TRN.
  • Avoid processing the transaction
    Do not proceed with invoicing or payments until the TRN is confirmed as valid.
  • Verify again on the FTA portal
    Cross-check the TRN using the official Federal Tax Authority (FTA) verification tool.
  • Maintain proper documentation
    Keep records of verification attempts and communications for audit purposes.
  • Seek professional advice if needed
    Consult a tax advisor if discrepancies persist or if there are compliance concerns.
