The Mexico country code is +52 — reaching Latin America's 2nd-largest economy + 129 million Mexicans across 32 federal entities, plus ~125 million mobile subscriptions across Telcel (América Móvil), AT&T México and Movistar Mexico. Since the 2019 numbering reform, all Mexican mobiles are 10 digits without the old "1" prefix.
Mexico was assigned +52 by the ITU in 1949, placing it in zone 5 with the rest of Latin America. The 2019 IFT numbering reform finally simplified Mexican phone numbers — here's what every Mexican LADA looks like today.
Mexico has used the +52 country code since 1949, when the ITU placed it in zone 5 alongside Brazil +55, Argentina +54, Colombia +57, Chile +56 and Cuba +53. The "2" suffix was the second single-digit slot in zone 5 — making +52 the shortest Mexican-Hispanic code.
Mexico's telecom industry is regulated by the IFT (Instituto Federal de Telecomunicaciones, founded 2013, replacing the older COFETEL). Three major mobile carriers operate: Telcel (~75M subs, owned by Carlos Slim's América Móvil), AT&T México (~22M), Movistar Mexico (~17M, Telefónica). All are GSM/LTE/5G.
Mexican area codes are called <b>LADAs</b> (Lada de Larga Distancia Automática — Long-Distance Direct-Dialing Code). Major LADAs: <b>55</b> Mexico City + State of Mexico (2 digits). <b>33</b> Guadalajara. <b>81</b> Monterrey. Tier-2/3 cities use 3-digit LADAs: <b>222</b> Puebla, <b>664</b> Tijuana, <b>998</b> Cancún, <b>442</b> Querétaro. Mexico has 380+ active LADAs.
Mexico simplified its mobile dialing in 2019. Before August 2019, calling a Mexican mobile required adding a "1" between the country code + LADA (so +52 1 55 1234 5678). The IFT abolished this on 3 August 2019 — now Mexican mobiles + landlines use the same format: +52 LADA NNNNNNNN. This made Mexican numbers compliant with E.164 international standards for the first time.
A Mexican phone number in international format is written as +52 LADA NNNNNNNN. For example, +52 55 1234 5678 for Mexico City (LADA 55), +52 33 1234 5678 for Guadalajara, or +52 998 123 4567 for a Cancún number (LADA 998 has 3 digits + 7 local).
Mexican numbers are always 10 digits total domestically — LADA (2 or 3 digits) + local subscriber (8 or 7 digits). There is no leading 0 in Mexican numbers (unlike France or Germany). Since the August 2019 IFT reform, mobile + landline numbers have the same format — no more "1" before the LADA when calling a Mexican mobile from abroad.
From the Zócalo in Mexico City to the beaches of Tulum, every Mexican number lives behind a +52. Pick the LADA that matches your customer city — CDMX 55, Guadalajara 33, Monterrey 81, Cancún 998.
Every country uses a different international exit code before the +52 Mexico country code. From any mobile, the + symbol replaces the exit code automatically — so +52 55 1234 5678 works worldwide. No leading 0 to drop + no "1" before the LADA since the August 2019 IFT reform.

Major LADAs are 2 digits (55 CDMX, 33 Guadalajara, 81 Monterrey); smaller cities use 3-digit LADAs. Total E.164 length is 12 digits including +52. No leading 0; no "1" before LADA (the 2019 reform removed that requirement).
+52 reaches Latin America's 2nd-largest economy, the USA's largest trading partner + the world's 10th-largest mobile market. Spanish + heavy US cross-border traffic.
Mexican banks (BBVA Bancomer, Santander México, Citibanamex, HSBC México, Banorte, Banco Azteca, NuMéxico) + the SAT (tax authority) + CFE (electric utility) + IMSS verify with +52 mobile numbers.
Mexico is the USA's largest trading partner (~$800B annual two-way trade, surpassing China in 2023). A +52 line is the cleanest single point of contact for US-MX business — Tijuana 664, Juárez 656, Reynosa 899, Matamoros 868.
A LADA 55 says "Mexico City — Polanco, Reforma, Santa Fe, Lomas, Roma-Condesa, Coyoacán". The largest Spanish-speaking city in the world (22M people). LADA 33 = Guadalajara tech corridor. LADA 81 = Monterrey industrial belt.
WhatsApp is dominant in Mexico (~90M users). Mexican banks SMS + WhatsApp OTPs to +52 numbers without throttling. Mercado Libre Mexico, Rappi, Didi México all verify via +52.
Most of Mexico (CDMX, Guadalajara, Monterrey) runs on CST (UTC−6 in winter, UTC−5 in DST summer) — the same clock as Texas + most of central US. Mexico abolished DST nationally in October 2022 (except border cities).
A +52 line opens Spanish-language conversations across LatAm. Mexican Spanish is the lingua franca for content + media across the region — telenovelas, Bimbo, Cemex, FEMSA all use Mexican Spanish for hemispheric reach.
Pick your LADA — 55 Mexico City, 33 Guadalajara, 81 Monterrey, 664 Tijuana, 998 Cancún — and start calling, texting + receiving BBVA + SAT + Mercado Libre OTPs from real Mexican customers.
