How to read a number

+525512345678

+52Country code
Mexico.
55Area code
Every Mexican number is 10 digits, starting with a 2- or 3-digit area code (55 is Mexico City). Mobiles and landlines share the same area codes — since 3 August 2019 the whole country dials 10 digits, and the mobile prefixes 044 and 045 and the long-distance prefix 01 were abolished, so a number alone does not tell you whether it is a mobile or a landline.
12345678Remaining 8 digits
The local number. Mexico allows porting, so the digits do not reveal the operator.

Written nationally as 55 1234 5678 — no 0 or 01 in front; within Mexico you simply dial all 10 digits.

Number ranges & quality

RangeTypeNotes
10 digits (2-digit area code + 8 digits, e.g. 55 XXXX-XXXX) Mobile carrier Since 2019 the 044 / 045 mobile prefixes were dropped, so mobile and landline numbers are both 10 digits. Some mobiles start with 1, but carriers cannot be reliably told apart.

ID requiredEvery mobile line must be registered (CRT guidelines, from 9 January 2026): foreigners use a passport; unregistered lines are suspended by last digit.

Physical SIMs can sign up without issues.

Carriers & prefixes

Mobile prefixes by carrier.

Number portability applies — a prefix only shows the original carrier.

Porting rules in full

Porting (portabilidad) is a legal right in Mexico: it is free and must be completed within 24 hours of the request (counted in business hours — a request made at the weekend is processed on the next business day). You need ID, a request form with your handwritten signature, and a 4-digit porting code (NIP) that your current operator sends by SMS reading "SU NIP DE PORTABILIDAD ES XXXX"; the rules forbid making the NIP conditional on a minimum balance. Debt does not block a port, but you still owe it, and contractual obligations such as returning equipment remain. The regulator has changed too: the IFT, which used to oversee this, has been replaced by the new telecoms regulatory commission CRT, and the IFT website is now a historical archive. Also, since 2019 every Mexican number is 10 digits and mobiles are written exactly like landlines, so a number does not even tell you whether it is a mobile, let alone the operator — which is why this site does not publish a prefix table for Mexico.

Network-experience stars are derived from the awards each operator won in the Opensignal report of 2025-10 (data collected Jun 01 - Aug 29, 2025): the most-awarded operator gets 5 stars, the rest proportionally, with a shared award counting as half. They reflect network testing only — not prices or customer service. Test report →

User share comes from the CRT (the telecom regulator), as of 2025-09. It shows how widely each operator is used — not how good its signal or service is. Official data →

    launched 2018 — the shared wholesale network (Red Compartida) went live

    Also known as the "Red Compartida" (shared network), built as a public-private partnership. It is wholesale-only and does not sell to individuals — its own site says you reach its network through the MVNOs (OMV) that resell it, so visitors cannot buy an "Altán SIM"; they buy brands like Bait below.

    No longer has its own network: Telefónica dismantled its access network between 2020 and 2022 and moved customers onto AT&T México’s. On 7 April 2026 Telefónica also agreed to sell its Mexican business to Melisa Acquisition LLC for USD 450 million, with closing subject to regulatory approval (Telefónica Q1 2026 results).

SIM cards & keeping a number

From 2026 every Mexican mobile line (prepaid, postpaid, eSIM) must be registered to its holder. The regulator CRT’s Guidelines for the Identification of Mobile Lines took effect on 9 January 2026: Mexicans use a CURP plus a voter card or passport; under article 20, foreigners only record their name, country of origin and passport number, with no facial check (per Milenio quoting the CRT). Each identity can register up to 10 lines (as reported across Mexican media).

The original 30 June 2026 deadline was replaced that same day, in the official gazette, by staggered suspensions by last digit: 0 by 15 August, 1 by 31 August, and so on to 31 December. Suspended lines can only call emergency numbers; registering restores them for free and the number isn’t lost. Foreign numbers roaming in Mexico are exempt for now — the CRT will set rules after the World Cup.

Other operators’ cycles (Expansión, April 2026, citing each operator’s terms): AT&T suspends 90 days after balance runs out and cancels after 365 days without a top-up; Movistar suspends after 180 days without calls or SMS; Bait cancels after about 150 days.

Keeping the number
Per Expansión (April 2026) citing Telcel’s Amigo lifecycle policy: for 119 days after balance or package expiry the line only receives calls and SMS; then 246 days fully suspended; then a 5-day cooling-off before cancellation and number recycling — about 370 days in total. Frozen balance can be recovered with a top-up within 365 days
ID check
Registration required: foreigners use a passport (name, country, passport number, no facial check); unregistered lines are suspended by last digit and can only call emergency numbers
SMS & calls
A normal Mexican number. Per Holafly: China is in Telcel’s “Mundial Especial A” roaming zone, and SMS sent without a package cost MX$9 each; receiving SMS pricing not verified; prepaid lines need balance to roam

Pros

  • Long lifecycle — about a year before the number is recycled
  • Foreigners only need a passport, no facial check (CRT)

Watch out

  • The line must be registered or it’s suspended by last digit
  • Telcel’s site couldn’t be reached from here; lifecycle based on a media report citing the official policy
  • Cost of receiving SMS in China not verified
