Overview
- Mobile operators must deploy secure registration and identity‑validation platforms within 30 days of the rule taking effect and then have 120 business days to link all active lines to identified users.
- Numbers not linked by the deadline will be suspended and limited to emergency and carrier customer‑service calls until the user completes registration.
- The requirement applies to prepaid and postpaid accounts, physical SIMs and eSIMs, corporate and institutional lines, and foreign users in Mexico, with exemptions only for machine‑only SIMs used for telemetry or tracking.
- Individuals must present an INE voter ID or passport plus CURP, while companies must provide RFC and proof of legal representation, and natural persons are capped at 10 registered lines unless they qualify as business entities.
- Operators face fines of 0.01% to 0.75% of revenues for noncompliance and must protect data under Mexico’s privacy law, with the rollout covering roughly 140–158 million lines and significant identity‑validation costs.
