Overview
- The national rollout is active and staggered by last digit, with the CRT reporting 73.2 million prepaid lines linked as of 19 August and the next deadline for numbers ending in 1 on 31 August.
- Operators began 72‑hour suspension windows after the first cutoff for numbers ending in 0 and have already reactivated about 2.35 million lines once users completed the linkage.
- Users must register through their mobile operator or the CRT portal using the phone number, CURP, an official ID and a camera-based identity check; the CRT says the process is free and does not store biometric data.
- Suspended prepaid lines retain emergency calls and can be reactivated after linkage but may block SMS one‑time codes used by banks and apps, creating possible disruptions to financial and account access.
- The CRT expects roughly 25 million inactive or promotional numbers to be depurated from registries as the process runs through December, a step that officials say removes unused entries rather than automatically stripping active users of their numbers.
