Mexico is requiring all mobile phone users to register their lines by June 30, 2026 [1].

The measure aims to eliminate anonymity in mobile telephony to improve public security. By linking every active line to a verified identity, officials intend to combat crimes such as fraud and extortion [3, 4].

Norma Solano, president of the Comisión Reguladora de Telecomunicaciones (CRT), said the registration process began on Jan. 9, 2026 [2]. Despite the months-long window, adoption has been slow. Only 17.33% of mobile lines were registered two months after the process started [5].

Users who ignore the deadline face significant restrictions. Lines that remain unregistered will be unable to receive emergency alerts and will be blocked from calling emergency numbers, including 911, 074, 079, 088, and 089 [2, 3].

The CRT said the June 30, 2026, deadline will not be extended [1, 5]. This strict timeline is part of a broader effort to ensure all telecommunications infrastructure is traceable, a move the regulator said is essential for national security.

Residents throughout Mexico must complete the registration through their respective service providers to maintain full functionality of their devices [1, 4]. The government is emphasizing the urgency of the trámite as the cutoff date approaches.

“Unregistered lines will be blocked from calling emergency numbers, including 911.”

The CRT's decision to block emergency service access rather than simply disconnecting lines suggests a strategy designed to coerce compliance through safety risks. By targeting the ability to call 911, the government is leveraging public safety as the primary motivator for registration, reflecting a high-pressure approach to eradicating anonymous communication networks used in criminal activity.
