Mexico mobile phone line registration deadline November 15, 2026, Digi Mart USA News: Because of low participation in the registration of telephone lines, Mexico’s Telecommunications Regulatory Commission (CRT) has announced an additional period for users to meet this requirement. The general deadline will be extended until December 31, 2026.
The initiative, implemented earlier this year, aims to ensure that each phone number is associated with the identity of its holder. Authorities hope this will reduce anonymity in communications and help combat crimes such as fraud and extortion.
However, registration will not take place simultaneously for everyone.
The schedule sets staggered dates based on the last digit of each cell phone number, so the next group of users must pay attention to its deadline. According to the CRT, people whose mobile number ends in 6 must complete the linking process before November 15.
Lines ending in 7 have a deadline of November 30.
This requirement mainly affects prepaid users who use SIM cards and make top-ups, as well as those who bought a SIM card and have not yet registered their personal data. People with additional phone lines that are not yet linked to their name should also pay attention.
Those with postpaid plans whose line was already associated with their holder at the time of contract do not need to repeat the procedure.
The CRT warns that failing to meet the deadline could have consequences for those who have not yet completed registration. Phone companies may temporarily suspend lines that remain unlinked once the deadline has passed.
This measure may be applied within 72 hours after the established date.
During a suspension, users will not be able to make or receive calls, send SMS messages, or use mobile data. They will lose access to the usual services of their phone line.
However, they will still be able to contact emergency numbers and citizen services, and continue receiving earthquake alerts. The suspension does not mean the number is permanently lost; users can recover service once they complete registration of their data with their phone company.
To avoid losing service, users can register their mobile number in two ways: online or in person at their phone company’s service centers. The procedure requires a valid identification that includes the CURP.
According to the CRT, no biometric data is stored. The process only associates the phone number with the CURP.
