Your mobile line needs your CURP: this is what changes
As of January 9, 2026, all telephone lines in Mexico—prepaid or plan—must be linked to the Unique Population Registry Code. The Telecommunications Regulatory Commission (CRT) promotes this measure.
Why now?
Authorities argue that it is a necessary tool to combat crimes such as extortion, fraud and kidnapping. The idea is to create an identified registry that allows illegal activities to be tracked.
According to the Center for Strategic and International Studies (CSIS), line tracing is common in other jurisdictions to dismantle criminal networks.
You have until June 30, 2026 to complete the process. If you don’t do this, your line will be suspended for conventional services: no outgoing calls or mobile data.
You will only be able to make emergency calls.
How to link your line step by step
You need three things:
- Your CURP
- Current official identification (INE or passport)
- The active line you want to register
The process is done directly with your company (Telcel, Movistar, AT&T, Bait) in their physical centers or digital platforms:
- Enter your company’s portal or app
- Search for “Identity Registration” or “CURP Linkage”
- Provide your number to receive verification code
- Upload identification and CURP data
- Confirm and save the digital receipt
The other side: privacy risks
The Electronic Frontier Foundation (EFF) organization warns about the dangers of centralizing this data.
Various experts point out that “the centralization of this data (CURP + telephone number) carries risks if the databases are violated.”
The authorities ensure that they comply with international standards to protect personal information. But the debate about security versus privacy is still open.
The essentials: if you use a mobile line in Mexico, this procedure is not optional. It is best to do it early to avoid service suspension.
