What +254 means

+254 is the country calling code for Kenya. The same code is written 00254 when you dial out from most of Europe, Africa and Asia, and 011 254 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

Mobiles start with 7 or 1 (written 07xx and 01xx nationally).

Converting to E.164

Take the number as written locally (0712 345678), drop the leading 0, then prefix +254. The result is +254712345678: 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 Kenya 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 Kenya 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.
