Phone numbers in Mexico (+52)

Dialling and writing numbers in Mexico

The trunk prefix is dialled in front of a number inside the country and dropped after the calling code; the international prefix is dialled to call out of it. The lengths and the leading digits below say which numbers the plan accepts and what their first digits tell you about the line type.

Lengths count the national significant number, the digits after the calling code, without the trunk prefix. Every value is read from libphonenumber’s metadata, release 9.0.41, which a lookup runs on.

One number in each of its written forms

This is libphonenumber’s example mobile number, formatted by libphonenumber. An example number can be in service, so read it as notation and never dial or text it.

The numbering plan for Mexico

Every phone lookup starts from the numbering metadata: it settles whether a number is valid for Mexico, how it is written nationally and internationally, and which line type its range belongs to. The example numbers below are libphonenumber’s examples of each line type’s format; one may be in service, so read them for their shape and never dial or text one as a test.

The regulator table behind a lookup here

CRT numbering plan (Mexico) (synced 2026-10-19, table version 2026-10-19). The table is complete: it lists every assigned block of its plan, so a geographic number outside it is called unassigned. A lookup names the block holder as carrier with carrier_source block_allocation — the original allocation, never who serves the number today.

• 640,342 blocks in the table: 640,342 allocated, 0 unassigned, 0 reserved.
• 100.0 % of the blocks are allocated.
• 100.0 % of allocated blocks name a holder.
• 36.9 % of allocated blocks settle the line type on their own (234,090 mobile, 2,066 VoIP).

Measured weekly (last on 2026-10-25) from the table itself. These are shares of the regulator’s own table, not of real traffic, and they say nothing about who serves any one number today.

Who publishes the table, its files and terms, and what the copy installed here holds are on its data source page.

What a lookup answers for a number here

Every number the plan accepts for Mexico comes back with its formats, its line_type and line_type_source, its region and timezones, and the is_fictional and is_disposable flags from the bundled fiction ranges and the synced list of SMS-receiving numbers. Because the CRT numbering plan (Mexico) covers Mexico, a lookup also answers carrier from the block holder and block_status for every geographic number, unassigned included.

America/Mexico_City: the whole country keeps one clock, so a lookup answers that zone for every number here.

Area codes in Mexico

Mexico has 59 area-code pages; each reads the same table for the blocks under its code, their original holders and the line types they settle.
