Mexico’s national numbering plan

What it is

Mexico’s public numbering plan lists every assigned range of the ten-digit plan with its operator and modality. The Comisión Reguladora de Telecomunicaciones took over the functions of the IFT, which was dissolved on 17 October 2025; the plan is still served from the former IFT’s numbering portal, which carries the IFT’s name.

What the copy installed here holds

Counts only. Holders are counted, never named, and no row of the table is republished here: the publisher’s own files are linked below. A version marked “retrieved on” is the day the file was fetched, because the file itself carries no date.

How the rows read, and what a number outside them answers

Every listed range reads as allocated to its operator; a CPP or MPP modality marks the range mobile, and a fixed range keeps the plan’s answer.

Complete for geographic numbers: while the copy installed here is under 45 days old, a geographic number outside every listed block answers unassigned_block.

The files

• Plan nacional de numeración (public download)A file served only in answer to a form on the portal page, never at a plain link; the file carries no date. Every assigned range (about 178,000) with its zone, operator, modality (CPP, MPP or FIJO) and assignment date.

The terms, as the publisher states them

The portal states no terms of reuse and no licence; its footer reads “Copyright © Sistema de Numeración y Señalización”. The terms have not been confirmed with the CRT.

What the table cannot say

• A regulator’s table records the original allocation of each block, never who serves a number today: a number ported to another carrier keeps its block.
• An allocated block says a number in it can be in service, not that it is.
• The counts are rows of the regulator’s own table, not numbers or traffic: a busy block and an empty one count once each.
• Mexican mobiles and landlines share the plan’s geographic numbering; only a CPP or MPP modality marks a range mobile.

The risk signals read from it

• virtual · the block is held by a virtual-number wholesaler or VoIP provider (+40)
