TRN verification UAE: checking a supplier or customer TRN

The FTA site lists TRN/TIN verification among its other links. It opens a form with separate fields for a TRN and a TIN, each protected by a captcha code. Enter the number exactly as printed, complete the captcha and submit; the result tells you whether the number is registered and the name it belongs to.

Check the returned name against the supplier's trade licence. A valid TRN belonging to a different company is as much a problem as an invalid one.

The Ministry's e-invoicing guidelines describe the TIN as the first 10 digits of the TRN. The TIN is what builds your e-invoicing participant identifier: 0235 followed by those 10 digits. Members of a VAT tax group each have their own TIN, even though the group files under the representative member's TRN.

The mandatory fields document asks VAT-registered sellers to show their 15-digit TRN as the seller tax identifier, and UAE-registered buyers' TRNs as the buyer tax identifier.

Build checks into the moments that matter:

• When onboarding a new supplier whose invoices will carry VAT.
• When a supplier sends new bank details or a new legal name.
• Before claiming a large input VAT amount on a one-off purchase.
• When setting up business customers ahead of e-invoicing go-live.
• Once a year across your top suppliers and customers.

When the AI agent reads a supplier bill, in Arabic or English, it captures the TRN printed on it and compares it with the TRN saved on the supplier record. A mismatch, a missing number or a TRN that is not 15 digits is flagged for review. The agent does not query the FTA tool itself; someone on your team runs the check on the FTA website and confirms the record. Firms that want a TRN review step added to supplier approval rules can request that customisation through hello@hellobooks.ai.
