# Iranian national identification number (code melli) (`ir_melli_code`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Ten-digit national identification number (code melli) printed on the Iranian national identity card and written as XXX-XXXXXX-X. Validators such as validator.js treat the last digit as a modulo 11 check digit over the first nine; no official description of the algorithm was found, so the record sets no checksum.
