Overview

CLI routes to Mexico

A CLI route to Mexico is a wholesale path that keeps the caller ID you send intact all the way to the handset. CLIRoutes only places CLI-tier traffic on paths that passed CLI test calls on Mexico’s main networks, and removes paths that stop passing.

Mexican CLI routes deliver your authorised number on Telcel, AT&T Mexico and Movistar networks. We test display per network and normalise legacy number formats before they reach the route.

Mexico is a large Spanish-language nearshore market for US companies and a major destination for collections and customer care.

Caller ID rules in Mexico

A practical summary for operations teams, not legal advice. Confirm current requirements with counsel before you launch.

Last reviewed

Caller-ID presentation

Callers must present a valid number. Consumers can register on REPEP, Profeco’s opt-out registry, and telemarketing to registered numbers is prohibited. Telecom regulation moved from the IFT to a new regulator in 2025, so check current guidance with counsel.

REPEP

The Public Registry to Avoid Advertising (REPEP), run by PROFECO, lets consumers opt out of marketing calls. Scrub against it.

Collections conduct

Collection calls are subject to rules on conduct and hours; keep agents and IVR scripts compliant.

Data protection

The federal law on personal data protection applies to call records and recordings.

Calling hours

Consumer-protection rules restrict marketing calls to reasonable daytime hours; check the latest PROFECO guidance.

Dialing & setup

Dialing Mexico correctly

  • Dial +52 and 10 digits for every number. The old “1” for mobiles and the 044, 045 and 01 prefixes are gone.
  • Most of Mexico is on Central Time without daylight saving since 2022; Baja California still follows US daylight saving.
  • Check REPEP before marketing calls, including mobile numbers.
  • Spanish-language scripts are expected; US-Mexico border traffic often switches language mid-call.

Caller ID best practice

Present a Mexican number you hold for domestic campaigns. Mexican numbers outperform US CLIs on Mexican handsets.

FAQ

Mexico CLI routes: FAQ

Can’t find what you need? Our routing team answers within the hour, around the clock.

Do you support collections campaigns into Mexico?

Yes, on CC and IVR routes for lawful collections, subject to local conduct and hours rules and our campaign review.

Should I use a Mexican CLI?

For Mexican consumers, yes. Local numbers get noticeably better answer rates than foreign CLIs.

Do I still need +52 1 for Mexican mobiles?

No. Since August 2019 all Mexican numbers are dialled as +52 plus 10 digits. Adding a 1 for mobiles now causes failures on many routes.

What is REPEP?

The Registro Público para Evitar Publicidad, run by Profeco. Consumers register to stop marketing calls, and companies must not call registered numbers for advertising.

Which time zone should my dialer use for Mexico?

Most of the country uses Central Time all year since daylight saving was abolished in 2022. Baja California and some border municipalities still change clocks with the US.

Which caller ID can I present on Mexico calls?

Only numbers you own or are authorised to use. Present a Mexican number you hold for domestic campaigns. Mexican numbers outperform US CLIs on Mexican handsets.
