What +47 means

+47 is the country calling code for Norway. The same code is written 0047 when you dial out from most of Europe, Africa and Asia, and 011 47 from the US and Canada. All three reach the same place: only the exit code in front of it changes. Norway uses no trunk prefix, so the national number follows the code unchanged.

Mobile numbers

No trunk prefix or area codes. Mobiles start with 4 or 9.

Converting to E.164

Take the number as written locally (406 12 345), add the +47 prefix (there is no trunk digit to remove). The result is +4740612345: 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 Norway 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 Norway 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.
