What each type means for the caller
- Toll-free: 800 or 888
- Free to the caller, usually only from inside the country; the business that owns the number pays for the call. 10 digits after +52.
- Premium rate: 900
- Charged above a normal call at a rate set by the service, with part of the charge going to the service provider. 10 digits after +52.
- Shared cost: 300
- The caller pays part of the cost and the owner pays the rest, so the price sits between a free and a normal call. 10 digits after +52.
- Personal number: 500
- A follow-me number that forwards to whatever phone its owner chooses, so the digits don't reveal the line behind it. 10 digits after +52.
Writing and dialling a Mexico toll-free number
Mexico has no trunk prefix, so the number is the same at home and abroad; in E.164 put +52 in front: 800 123 4567 becomes +528001234567. Many freephone numbers still only accept calls from inside Mexico, and a call from abroad that does connect is usually charged.
Toll-free and premium numbers in a phone list
In a lead or customer list, a toll-free number usually reaches a company line rather than a person, and a premium-rate number costs you money to call. The free toll-free number checker flags them in a pasted list or CSV, and the Mexico phone number format page covers mobiles and landlines.

- Ranges, lengths and examples: Google libphonenumber numbering-plan data (libphonenumber-js 1.13.15), the data our validator uses.
- Official plan: ITU-T E.164 national numbering plan for Mexico. The regulator’s filing is the authority when the two disagree.
The numbering plan only knows what a range was issued for.
In the US and Canada mobiles and landlines share the same prefixes, and anywhere a number can be ported or reassigned the range stops telling the whole story. A live carrier lookup asks the network data instead, which is what Pro + Phone ($49.99/mo) adds.
