Europe · +47

Norway phone number format

  • Country code +47
  • No trunk prefix

Reviewed by Sujan ThapaliyaLast updated

What does a Norway phone number look like?

8 digits, always. No area codes. Landlines are written +47 XX XX XX XX and mobiles +47 4XX XX XXX. In full international (E.164) format a Norway mobile is written +4741234567: the country code +47, and no spaces or punctuation.
The anatomy of a Norway phone number under ITU-T E.164: country calling code 47, then the national destination code, then the subscriber number, to a maximum of fifteen digits after the plus. Nationally a Norway number is written +47 XX XX XX XX; in E.164 the prefix and the spacing both come off.
National formatting is for people. E.164 is for databases, APIs, and caller ID — store Norway numbers in the right-hand form.

A quirk of Norway numbering

Norwegian mobile numbers start with 4 or 9; landlines start with 2, 3, 5, 6, or 7.

Validation

How to validate a Norway number

Validating a phone number is three separate checks, and conflating them is the usual source of bugs:

  1. Format: does it match the shape for Norway? 8 digits, always. No area codes, after the country code .
  2. Allocation: is the prefix actually in use? A number can be the right length and still belong to an unallocated range.
  3. Reachability: is there a live subscriber? Only a carrier lookup (HLR or equivalent) answers that, and it is the only check that catches disconnected numbers.

For form validation, check format only and be permissive: accept spaces, dashes, brackets, and a leading 0 then normalise. Rejecting a real customer because they typed their own number the way they normally write it is a far more expensive error than storing one badly formatted row.

Store in E.164 (+4741234567) and format for display at render time. Storing the display format is how a database ends up with the same person recorded four different ways.

Frequently asked questions

What does a Norway phone number look like?
8 digits, always. No area codes. A landline is written +47 XX XX XX XX and a mobile +47 4XX XX XXX. In full international format that becomes +4741234567.
How do I write a Norway number in international format?
Start with +47, then append the rest with no spaces or punctuation. +47 21 23 45 67 becomes +4721234567.
How many digits is a Norway phone number?
8 digits, always. No area codes.
How do I tell a Norway mobile from a landline?
By the prefix. Mobiles follow the pattern +47 4XX XX XXX, while landlines follow +47 XX XX XX XX.
Should I store phone numbers with the plus sign?
Yes. Store every number in E.164: leading +, country code, national number, no spaces or punctuation, up to 15 digits. It is the only format that is unambiguous internationally, and it is what makes deduplication work. Format for display, store canonical.
