Mexico extends deadline for phone number-CURP linkage

Mexico's telecommunications regulator, the CRT, has extended the deadline for linking personal phone numbers to the CURP national identification registry. Initially set for June 30, the new deadline allows users to complete this linkage throughout July and into the remainder of the year, with specific dates determined by the final digit of their phone number.

Failure to link a phone number to a CURP will result in service suspension, restricting users to emergency calls and preventing them from receiving alerts, such as earthquake warnings. The CRT has established a new schedule that begins in August, with users whose numbers end in 0 having until August 15 to comply, followed by subsequent deadlines for other digits through December 31, 2026.

While July offers a grace period, users can proactively complete the registration. The process involves providing official identification (INE or passport), a certified CURP, and the phone number. The link for registration is typically sent via message by the service provider. This requirement primarily applies to prepaid plans, as postpaid subscribers may have their lines registered automatically. The extended deadline provides a significant window for compliance, ensuring continued service for millions of users.

those users who do not link their phone line to the CURP will lose their telephone line service, so they can only make calls to emergency numbers, citizen attention and receive alerts in case of an earthquake.
