Question 1

Does it return the current carrier or the original one?

Accepted Answer

The current one. Every number is checked against Mexico's number portability database (more than 80 million ported numbers, updated daily). When a number was ported, the response also includes the previous carrier (`operadora_anterior_corto`). If the number was ported to a carrier that cannot be identified, `operador_identificado` is `false` and `operador` is `DESCONOCIDO`, so you never get a guess.

Question 2

Can it tell whether a Mexican number is mobile or landline?

Accepted Answer

Yes. Since 2019 Mexican numbers carry no mobile prefix, so libphonenumber returns `FIXED_LINE_OR_MOBILE` for every Mexican number. This API looks each number up in the national numbering plan and returns `tipo`: `movil` or `fijo`, plus the state, municipality and locality of its numbering range.

Question 3

How fresh is the data?

Accepted Answer

The number portability database is updated every day with the new ports (around 40,000 numbers a day, roughly 1.2 million a month). Numbering ranges, carriers and locations come from Mexico's official National Numbering Plan (CRT, formerly IFT). Use the `/status` endpoint to check the service and the size of the loaded data.
