What +52 means
+52 is the country calling code for Mexico. The same code is written 0052 when you dial out from most of Europe, Africa and Asia, and 011 52 from the US and Canada. All three reach the same place: only the exit code in front of it changes. Whichever one you use, the national trunk 0 is dropped once the country code is in front.
Mobile numbers
Since 2019 mobiles no longer need the old 1 or 045 prefixes: ten digits is the whole number.
Converting to E.164
Take the number as written locally (55 1234 5678), drop the leading 0, then prefix +52. The result is +525512345678: no spaces, no dashes, no parentheses. Store that, and format for display only when you show it to a human.
Why not do it with a regex
A pattern that matches Mexico numbers today breaks the moment a new mobile range is allocated, and it cannot tell you whether the number is actually assigned. The tool above runs the same numbering-plan engine as our phone validation API, so it also reports line type and region rather than just shape.
That is how a Mexico number is written. Whether a whole list is worth dialling is the free call list cleaner, or check one number on the spam phone checker.
