Since January 2026, registering cell phones with the CURP is mandatory. This opened a question among users: how many numbers are really associated with my identity?
Free online consultation
The Telecommunications Regulatory Commission enabled a platform to verify the lines registered in your name and detect irregularities. The process is free and is carried out on the official site: portal.crt.gob.mx/plataformas-de-consulta-de-las-companies-telefonicas.
You must select your telephone company and provide your CURP. The system will display the linked numbers. Only the owner accesses the information, with the aim of protecting personal data.
If you detect an unknown number
The authorities recommend starting the cancellation from the same platform or contacting the operator to report possible misuse of your identity. Reviewing periodically helps prevent fraud, extortion or hiring without consent.
