What is Biometric CURP and How Does it Work?
Unlike traditional identification, the biometric CURP uses advanced scanning technology to capture your complete physical profile—and it’s completely free. The process is handled by trained Civil Registry personnel with security standards matching electronic passports.
| What Gets Captured | Details |
|---|---|
| Fingerprints | All 10 from both hands |
| Iris Scans | Both eyes (left and right) |
| Facial Photo | High-resolution image |
| Digital Signature | Encrypted security element |
Once registered, your document includes an electronic signature, photo, and QR code that links directly to your biometric data.

Why Mexico Implemented Biometric CURP in 2026
President Claudia Sheinbaum’s administration built the biometric CURP as part of the “Unified Identity Platform” to tackle Mexico’s disappearance crisis. The system connects data across Renapo (population registry), National Forensic Database, Attorney General’s Office (FGR), state prosecutors, and National Intelligence Center. Real-time identity verification helps locate missing persons and combat identity theft. It also speeds up transactions with banks and government agencies.
