A TRN must appear on every tax invoice issued by the business. It is also used to verify supplier VAT registration status — which matters because you can only reclaim input VAT on invoices from genuinely registered suppliers. The FTA provides a public TRN verification tool on tax.gov.ae. Businesses that issue invoices showing a TRN they do not hold, or that charge VAT without being registered, are committing a criminal offence under UAE VAT law — not merely a civil compliance breach.
TRN verification: Check any UAE supplier TRN at tax.gov.ae → TRN Verification. Takes 30 seconds and can save significant VAT reclaim disputes later.
