Overview
- The CRT’s portal now lets users check which mobile lines are tied to their CURP using a live identity test designed to prevent third‑party registrations.
- Users can remove unrecognized numbers online or at carrier service centers, receiving a unique transaction receipt and SMS confirmation, with up to three attempts allowed.
- Carriers must inform users how many lines are associated with their identity while displaying only the last four digits of each number for privacy.
- Lines not linked by June 30, 2026 will be suspended from July 1 and limited to emergency calls and carrier support, with full service restored once registration is completed.
- Registration requires only a name and CURP, biometric checks are not stored, and operators including Telcel, Movistar, AT&T and Bait hold the database for investigative collaboration without direct authority access.
