The Telecommunications Regulatory Commission (CRT) postponed the mandatory registration of mobile lines. The deadline, scheduled for June 30, was extended to facilitate the process for millions of users.
New registration calendar
The new term applies only to unregistered prepaid lines. It will be staggered according to the last digit of the number. The dates range from August 15 to December 31, 2026.
So far, more than 63 million lines are registered: 40.2 million prepaid and 22.8 million postpaid. Millions are still missing.
Unregistered lines will be suspended by telephone companies within a period of up to 72 hours. During that time they will only be able to call emergencies, citizen services and their operator. Service is restored upon completion of registration.
Mexico closed 2025 with around 161.6 million active mobile lines, a penetration of more than 124% of the population. Additionally, if a line is used to commit a crime, authorities may request information directly from companies.
