UAE TRN validator

Check the format of a 15-digit UAE Tax Registration Number. Validate one TRN live as you type, or paste a CSV for batch validation. Useful when cleaning a supplier list before reconciling a VAT return.

Validate one TRN

Paste a 15-digit TRN. The check is format-only — the FTA does not publish a binding checksum. For binding validation, look the TRN up on the FTA portal at tax.gov.ae.

Validate in bulk

Paste a CSV (or one TRN per line). We'll check format on every row and show you which rows pass.

What this tool checks

  • Length is exactly 15 digits after stripping dashes and spaces.
  • Leading digit is 1 (mainland VAT registration) or 3 (Excise registration).
  • No non-numeric characters survive normalization.

What it does NOT check

The FTA does not publish a binding checksum or modulus algorithm for the remaining 14 digits. A format-valid TRN may still be unassigned, deregistered, or belong to a different legal entity than expected. For binding validation, look the TRN up on the FTA portal at tax.gov.ae.
