Phone Lines Ending in 1 Face Sunday Registration Deadline

Mexico City — Mobile phone users whose numbers end in 1 have until Sunday, Aug. 31, to register their lines with their carrier, according to Mexico’s telecommunications regulator.

The deadline is part of a staggered schedule set by the Federal Telecommunications Commission (CRT) to link every mobile line to a named account holder. The process is done directly through each phone company and does not require biometric data.

What happens if you don’t register?

Missing the deadline does not mean the phone will stop working immediately. It marks the end of the registration period for lines ending in 1. Carriers may then begin suspending lines that remain unlinked during the following 72 hours.

A suspended line is not permanently lost, the CRT says. Service can be restored once the user completes the registration with their carrier.

How to register

Registration requires a valid official ID with a CURP (unique population registry code). It can be done from the phone through the carrier’s platform or in person at a customer service center. The CRT advises using official carrier channels and avoiding suspicious links or pages requesting additional information.

The CRT has set up a portal called “Registra tu línea” (Register your line) where users can check their deadline and access official carrier platforms. The process can be completed even if the line has no balance, and the portal remains available for restoring service after a suspension.

Lines ending in other digits have different deadlines continuing through December, but users can register early if they wish.
