Overview
- The Diario Oficial publication on June 30, 2026 put a prórroga into force that replaces a single June 30 deadline with a staggered calendar running from August 15 to December 31, 2026 based on the phone's last digit.
- Operators must implement a remote registration platform, send twice-weekly SMS reminders and daily notices in the final seven days, and suspend unlinked prepaid lines within 72 hours after each group's deadline.
- The rules let users register remotely or in person, add a 'prueba de vida' check for in-person verifications, expand acceptable IDs for foreigners, and limit displayed digits when checking which numbers are linked to a CURP.
- CRT reported about 63 million lines linked by June 25, 2026, leaving tens of millions of prepaid lines still unlinked so large-scale registration activity and operator messaging are expected through December.
- Officials say the policy aims to curb anonymous SIM use in crimes such as extortion and fraud while keeping CURP linkages with operators rather than a centralized state database, but privacy groups and legal challenges remain part of the rollout.
