The Telecommunications Regulatory Commission (CRT) confirmed an extension for the mandatory registration of mobile telephone lines. The deadline scheduled for June 30 was postponed. The measure seeks to facilitate compliance for millions of users who have not yet linked their number.
New staggered calendar
The new term applies only to pending prepaid lines. It will be done in a staggered manner taking the last digit of the number as a reference. The deadlines are from August 15 to December 31, 2026.
According to the latest CRT report, so far more than 63 million mobile lines have been registered: 40.2 million prepaid and 22.8 million postpaid. However, there are still millions of users to complete the process.
The authority warned that lines not registered within the deadline will be suspended by telephone companies for a period of up to 72 hours. During that time they will only be able to make calls to emergencies, citizen services and their provider. Full service will be restored once registration is complete.
At the end of 2025, Mexico had around 161.6 million active mobile lines, a penetration of more than 124% of the population. The CRT added that, when a line is used in a crime, the authorities may request information directly from the telephone companies.
