Mexico Mandates Mobile Phone Registration with CURP; Deadlines Set

Mexico is implementing a mandatory registration process for all mobile phone lines, requiring users to link their service with their Unique Population Registry Code (CURP). This initiative, aimed at bolstering citizen security and combating crimes like fraud and phone extortion, aligns Mexico with regulatory practices in 166 other nations.

Despite initial reluctance from some segments of the population, government extensions have provided users with definitive deadlines. The program seeks to eliminate anonymity in telecommunications. Currently, less than 50% of mobile lines nationwide have completed this mandatory registration.

The Federal Telecommunications Institute (CRT) has established a clear schedule for prepaid users who have not yet registered. The deadlines are staggered between August and December 2026, based on the final digit of the user's phone number. Companies will suspend service within 72 hours after the assigned deadline for those who fail to comply.

The registration process must be completed directly with the user's service provider. The deadlines are as follows: ending in 0 by August 15; 1 by August 30; 2 by September 15; 3 by September 30; 4 by October 15; 5 by October 31; 6 by November 15; 7 by November 30; 8 by December 15; and 9 by December 31.

Users who miss their deadline will face temporary suspension of mobile data, outgoing calls, and SMS messaging. However, essential functions like calling emergency services (911), contacting citizen helplines, reaching their phone company, and receiving earthquake alerts will remain accessible.
