Overview
- Authorities confirm the credential becomes mandatory in February 2026 for health services, social program payments, banking, school enrollment, official documents like passports and licenses, and migration procedures.
- Active since October 2025, free registration is conducted in person at Registro Civil and RENAPO modules and via mobile units, with a one-time capture of data.
- Applicants must present a certified birth certificate, validated traditional CURP, a valid photo ID, recent proof of address, and active contact information, while minors must attend with a parent or legal guardian.
- Collected biometrics include fingerprints from both hands, a facial photograph, iris scans and an electronic signature, which are stored by the Interior Ministry through RENAPO.
- A limited online path is available through Llave MX for people who previously submitted biometrics to SAT or the Foreign Affairs Ministry, as civil-society comparisons spotlight the need for legal safeguards, audit trails and fallback options.
