Check the full registered name, licence number, issuing authority and legal form through an official register. Do not overlook suffixes, branches or group entities when comparing Persian, English and Arabic documents.
Match the contracting party against the quotation, invoice and receiving account holder. If payment to another entity is requested, independently establish and document its authority and the basis for receiving your money.
A trade licence identifies a registered business and its permitted activities; it does not guarantee solvency or performance. If you rely on a parent company, document that entity's undertaking or guarantee separately.
A practical next step
Save the official register result before signing, and resolve any discrepancy in the entity name, licence number or receiving account.
