Mexico Cell Phone Registration: Deadline, CURP & What Happens If You Don’t Register
Mexico’s new requirement for cellular phone registration, which began on January 9, 2026, is now underway. The mandate requires all mobile phone lines to be linked to a user’s official identification in an effort to curb fraud and extortion, and users are urged to complete the process before the deadline.
The regulation applies to both prepaid and postpaid plans, according to information published by El Universal. The goal is to improve security in telecommunications by tying each number to an identity.
What is the mandatory phone line registration and what is its purpose?
The mandatory registration is a process by which your cell phone number is linked to your official identity, as part of a strategy to improve security in telecommunications.
The main objectives are:
- Reduce extortion calls
- Combat telephone fraud
- Facilitate user identification in investigations
This type of measure has already been implemented in other countries as part of digital security policies.
What is the deadline to register your cell phone number?
The deadline set by the authorities is June 30, 2026.
So you have until that day to complete the registration of your phone line. After that date, restrictions may apply if you have not completed the process.
What happens if you don’t register your line before the deadline?
If you do not complete the registration on time, your line will be temporarily suspended.
During the suspension:
- You will not be able to produce normal calls
- You will not be able to send messages or use mobile data
- You will only be able to communicate with emergency numbers such as:
- 911
- 089
- 088
- Operator assistance lines
An significant point is that suspension does not waive your payment obligations, so you will still have to pay your plan if you have one contracted.
The line can only be reactivated once you complete the registration.
What do you need to register your cell phone number?
The process is simple and requires three basic elements:
- CURP
- Valid official identification
- Active telephone line
You do not need additional documents if your information is in order.
Where and how can you register?
You have two options to complete the process:
1. In person
By going to a branch of your telephone company.
2. Online
You can do it from the official portal enabled by the authorities:

On this site you will find direct links to the official pages of each operator to complete the process securely. Telcel, for example, began offering this service on January 9, 2026, as reported by Telcel’s registration page.
Does this registration apply to all users?
Yes. The measure applies to:
- Prepaid (top-up) users
- Users with rental plans
Regardless of the type of line, all must be registered.
What Consider keep in mind before June 30
- Registration is mandatory
- Applies to all active cell phone lines
- If you do not comply, your line will be temporarily suspended
- You can do it online or in person
- The process is quick and with few requirements
This process represents an important change in how mobile lines are managed in Mexico. If you have questions, it is best to contact your operator directly or use the official portal to ensure that your number is properly registered before the deadline.
