Mexico Phone Lines Ending in 6 Must Be Linked to CURP by Nov. 15
Mobile numbers ending in 6 face a Nov. 15 deadline to be linked to the owner's CURP, Informador reports. Who must register, what ID you need and how to do it.
Mexican cell phone users whose number ends in 6 have until Nov. 15 to link the line to their CURP, the national population ID code, Guadalajara newspaper Informador reported. The Telecommunications Regulatory Commission (Comisión Reguladora de Telecomunicaciones, CRT) requires the registration to fight phone fraud, and lines left unregistered could have calls and mobile data suspended.
The general deadline for the program was pushed back to Dec. 31, 2026, after few people signed up at first, according to Informador. Individual cutoff dates depend on the last digit of each number.
Who has to register by Nov. 15
The mid-November deadline applies mainly to prepaid lines whose number ends in 6, the kind people top up at convenience stores or supermarkets, the report said. It also covers anyone who bought a new SIM card without giving the seller personal details and anyone with extra lines not yet registered in their name.
Postpaid customers whose identity was checked when they signed their contract do not need to repeat the process, according to Informador. If your number ends in a different digit, the CRT’s official calendar lists your turn.
What this means for foreign residents and newcomers
Anyone in Mexico City using a prepaid Mexican SIM, including many people who recently moved here, falls under the rule if the line is not yet tied to an identity. The only requirement is a valid official ID that shows the CURP, such as a voter card or passport, the report said. Foreign residents should check that the ID they use carries a CURP, since the registration is built around that code.
The CRT launched the program early this year to end anonymous mobile lines nationwide. Security authorities want to cut phone extortion and online fraud by matching each SIM to its real owner. The agency has said no biometric data is stored during the process, Informador reported.
How to link a line to your CURP
Telcel, AT&T and Movistar have set up online platforms, so the process can be done without visiting a store. You can check a line’s status on the carrier’s official site.
- Confirm in your phone settings that the number ends in 6.
- Have an official ID ready that shows your CURP clearly.
- Use only your carrier’s certified app or verified website, since scammers send fake registration links.
- Register secondary lines too, such as phones used by children or older relatives that you pay for.
- Keep the confirmation text message, email or a screenshot once the carrier confirms the link.
Lines ending in other digits have later dates on the CRT calendar, with Dec. 31, 2026, as the final general deadline.
