Mexico is the natural first stop for companies extending voice coverage into Latin America: it shares the world's busiest land trade corridor with the United States, hosts one of the region's largest Spanish-speaking consumer bases, and runs a modern, fully ten-digit numbering plan that makes routing straightforward. A Temptera Mexican DID gives your business a dialable local identity under +52 — whether that means a 55 number in the capital or an 800 toll-free line for nationwide customer care — terminated directly onto your own SIP platform.

Mexico numbering plan: prefixes and formats

Mexico runs a closed ten-digit numbering plan under country code +52. Since the national dialling reform of August 2019, the old trunk prefixes 01 (long distance), 044 and 045 (mobile) have been abolished: every call inside Mexico, fixed or mobile, local or long distance, is dialled as the same ten digits. The extra digit 1 that international callers previously inserted after +52 to reach mobiles was withdrawn in the same reform, so a single format now works from anywhere in the world.

Geographic numbers are organised around area codes known as claves lada:

  • Two-digit codes serve the three largest metropolitan areas — 55 for Mexico City, 33 for Guadalajara and 81 for Monterrey — each followed by an eight-digit subscriber number.
  • Three-digit codes cover the rest of the country, for example 222 for Puebla and 998 for Cancún, followed by a seven-digit subscriber number.
  • Toll-free service uses the 800 prefix, historically dialled as 01 800 and now reached in the plain ten-digit form like any other number.

Mobile numbers are no longer a visibly separate class in dialling: they live inside the same lada structure and are dialled identically to fixed lines, one of the traits that makes the Mexican plan unusually clean to integrate into international routing tables.

Who regulates numbering in Mexico

Numbering in Mexico is governed by the Instituto Federal de Telecomunicaciones (IFT), the autonomous federal regulator for telecommunications and broadcasting. The IFT administers the national numbering plan, decides how the ten-digit space is structured, and assigns blocks within geographic ladas and non-geographic classes such as 800 toll-free to licensed carriers.

Beyond allocation, the IFT sets the conditions under which assigned ranges may be put into service, including the end-user registration and documentation rules that carriers must apply before activating numbers for customers. It was the IFT that drove the 2019 consolidation to uniform ten-digit dialling, and its ongoing management of the plan is why Mexican numbers behave so predictably for cross-border voice operators today.

Documents and verification for Mexico numbers

Mexico does not apply one document list to every number; the evidence you need depends on the class of range you order. For many geographic ranges the baseline is an identity document — a passport or national ID for the responsible individual, alongside basic details of the business that will use the number. Some ranges additionally call for proof of a Mexican address, the local comprobante de domicilio concept familiar to anyone who has opened an account in the country, and certain classes expect evidence of local incorporation, such as company constitution documents or an RFC tax registration.

Rather than asking you to guess which of these applies to a 55, 81 or 800 range, Temptera shows the exact requirement set for the specific Mexican range you select at order time, so compliance review starts with the right paperwork on the first pass.

What businesses use Mexico numbers for

Mexican numbers earn their keep in scenarios shaped by the country's real economic geography:

  • Nearshoring and manufacturing supply chains. Automotive, aerospace and electronics plants clustered around Monterrey and the Bajío corridor coordinate daily with US and European partners; an 81 or regional lada number lets suppliers, logistics providers and plant managers reach your team on a domestic Mexican call.
  • Cross-border customer service for the US–Mexico corridor. Firms selling into Mexico from abroad use 55 Mexico City numbers or the national 800 class so Mexican customers dial a familiar local or toll-free format while calls terminate on contact-centre agents anywhere in the world.
  • Fintech and digital services in the capital. Mexico City's dense fintech and e-commerce scene relies on recognisable 55 numbers for verification callbacks, collections outreach and account support, where an obviously foreign caller ID would depress answer rates.

How to get a Mexico number

  1. Pick your Mexican footprint — a lada such as 55 (Mexico City), 33 (Guadalajara) or 81 (Monterrey), a regional three-digit code, or the national 800 toll-free class.
  2. Review the document classes the chosen +52 range requires; Mexico differs range by range, and the exact list appears before you confirm the order.
  3. Upload the requested identity, address or company-registration evidence and submit the order for compliance checking.
  4. Once the range clears, route the ten-digit Mexican number to your own SIP trunk or PBX destination from the portal.
  5. Place test calls from a Mexican fixed line and a mobile to confirm the uniform ten-digit dialling reaches your platform, then go live.

Frequently asked questions

What does a Mexico virtual number look like when I buy one?

Every Mexican number is ten digits after the +52 country code. If you take a Mexico City DID it starts with the two-digit lada 55 followed by an eight-digit subscriber number; a Puebla or Tijuana number starts with a three-digit code such as 222 or 664 followed by seven digits. Callers inside Mexico dial the same ten digits you publish internationally, with no trunk prefix in front.

Can Mexican mobile phones call my +52 virtual number without extra prefixes?

Yes. Mexico abolished the old 01, 044 and 045 dialling prefixes in its 2019 numbering reform, so fixed and mobile callers across the country now dial the same ten-digit string. The extra 1 that foreign callers once inserted after +52 to reach mobiles was withdrawn at the same time, which means one uniform format works from any Mexican handset or from abroad.

Do I need a Mexican company to get a number in Mexico City or Monterrey?

Not necessarily for every range. Requirements in Mexico vary by number class: some geographic ranges accept a passport or other government identity document plus business details, while certain ranges ask for proof of a Mexican service address, and a few expect local incorporation evidence such as an acta constitutiva or RFC tax registration. The exact document set for the specific range you select is displayed at order time, before you commit.

Is there a toll-free option under +52 for customers calling from inside Mexico?

Mexico operates a national toll-free class on the 800 prefix, which domestic callers once reached by dialling 01 800 and now reach with the plain ten-digit form. An 800 number under +52 lets Mexican consumers phone your support or sales desk without charge to them, while the call is handed to your SIP infrastructure wherever your agents actually sit. Any onboarding conditions for the 800 class appear during checkout.

Which cities in Mexico can I choose an area code for?

Mexican geographic codes, known locally as claves lada, split into two-digit codes for the three biggest metropolitan areas — 55 for Mexico City, 33 for Guadalajara, 81 for Monterrey — and three-digit codes for everywhere else, from 222 in Puebla to 998 in Cancún. Choosing the lada that matches your target market gives your outbound and inbound presence a recognisably local footprint; current selectable cities are listed in the ordering flow.
