Overview

• President Claudia Sheinbaum said enrollment is optional, no fees will be charged to citizens, and institutions cannot require the biometric CURP for services.
• RENAPO director Arturo Arce Vargas announced that beginning in mid-October the biometric CURP will be emailed to people who have registered, with QR and other security features and no physical card issued.
• Pilot enrollment is underway at roughly 140–145 modules nationwide, with specific sites operating in Hermosillo, Sonora, and Chilpancingo, Guerrero.
• Llave MX will support online processing and, with explicit consent, may reuse existing biometric records from agencies such as INE or SAT to complete the process remotely.
• The reform’s scope has prompted confusion over future requirements, as some reports cite a February 2026 mandate, a claim contradicted by current official statements and subject to pending secondary rules.
