Overview
- The nationwide registration requires each mobile number to be linked to a holder’s CURP plus an ID and a selfie for biometric verification, and the CRT says unregistered lines will be suspended from July 1 if not linked by June 30.
- Official and industry counts vary, but multiple reports show only about 48 million to 56 million lines have been registered so far, representing roughly 30 to 39 percent of active lines and leaving tens of millions unregistered.
- Suspended lines will lose voice, SMS and mobile data functions except for emergency calls and alerts, which will block receipt of one-time passwords and can cut off access to services such as Llave MX, SAT Móvil, IMSS Digital and city apps.
- Privacy concerns have risen after early reports of data exposures and a citizen in Aguascalientes won an amparo challenging the mandatory linkage on constitutional and data-protection grounds, a case that could shape future court rulings.
- Carriers including AT&T publicly deny linking numbers without user consent and the CRT offers an online tool to check which numbers are tied to a CURP, while industry sources say authorities may privately weigh options to limit mass disruption.
