Overview
- Applicants must sign in with a Llave MX account on the official Registro Civil portal (miregistrocivil.gob.mx) to request and pay for a certified digital birth certificate.
- The digital certificate carries the same legal validity as a paper copy for school enrollment, banking, scholarships, pensions and other formal procedures.
- Fees are set by each state, with Mexico City charging 98 pesos in 2026, while other entities range from just over 50 pesos to above 200 pesos, payable online or via authorized banks.
- Creating a Llave MX account is free at llave.gob.mx and requires CURP verification, a security check, an active email and mobile number, and a password.
- After payment, the system provides an estimated validation time and then enables a secure PDF download, with authorities urging users to verify they are on the official portal to avoid fraud.
