On Friday, January 9, 2026, Mexico launched a mandatory cell phone line registration program, aiming to strengthen security controls and prevent phone fraud by linking every mobile number to a verified user. But with just one month left before the registration deadline, the results are far from what authorities expected.

According to the Comisión Reguladora de Telecomunicaciones (CRT), out of approximately 158 million mobile lines in the country, only about 30 million have been registered so far. That’s less than 30% of the total—leaving around 128 million lines unregistered as the deadline approaches.

What Happens If You Don’t Register Your Number?
The official guidelines, published in the Diario Oficial de la Federación (DOF), state that mobile service providers must temporarily disable any line not linked to a registered user. This suspension will begin on July 1, 2026, for all unregistered numbers.

Here’s what you need to know:
– Suspended lines will only be able to make emergency calls (911, 089, 088, etc.) or contact operator support.
– The suspension is temporary, lasting until the registration process is completed.
– Even if your line is suspended, you’re still responsible for paying your phone plan or device contract.

Why Are So Few People Registering?
Despite the looming consequences, skepticism remains high among the Mexican population. Many are wary of the process, which is reflected in the low registration numbers. This has led authorities to consider extending the registration deadline.

To boost participation, the CRT has launched a nationwide campaign focused on social media, official government websites, telecom operators, and mass media—including public transportation systems like Metro and Metrobús.

With just a month left before the cutoff, millions of users—especially migrants, expats, and digital natives—face a choice: register their lines or risk losing access to regular mobile services. The coming weeks will reveal whether the government’s push can overcome public hesitation and reach its ambitious security goals.
