What +48 means
+48 is the country calling code for Poland. The same code is written 0048 when you dial out from most of Europe, Africa and Asia, and 011 48 from the US and Canada. All three reach the same place: only the exit code in front of it changes. Poland uses no trunk prefix, so the national number follows the code unchanged.
Mobile numbers
No trunk prefix. Mobiles start with 45, 5, 6, 7 or 88.
Converting to E.164
Take the number as written locally (512 345 678), add the +48 prefix (there is no trunk digit to remove). The result is +48512345678: 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 Poland 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 Poland 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.
