- Norway.
- 4First digit
- A mobile number can only start with 4 or 9 — the numbering regulation gives those two whole ranges to mobile services. Norway has no area codes and no trunk prefix, so domestically you just dial the 8 digits.
- 1234567Remaining 7 digits
- Allocated to carriers in blocks, but numbers are portable, so they don’t reveal who serves it now.
Norwegians write the 8 digits in groups of 2-3-3 or 2-2-2-2: 412 34 567 and 41 23 45 67 are the same number.
Number ranges & quality
| Range | Type | Notes |
|---|---|---|
Starts with 4 or 9, 8 digits |
Mobile carrier | Norwegian numbers are always 8 digits with no area codes. The numbering regulation (nummerforskriften § 16) gives 40000000–49999999 and 90000000–99999999 to mobile services. Nkom publishes the full allocation register — who holds each block and which are free — but a single 4x or 9x range is shared by Telenor, Telia, ChiliMobil, Erate and others, and numbers are portable on top of that, so the prefix doesn't identify the operator. |
2x–3x (8 digits) |
Other | Landline ranges: 20000000–39999999 are 8-digit fixed numbers (5x–7x are geographic too). Numbers from 800 to 899 are special-service numbers, and 80000000–80099999 must be free for the caller. A Norwegian number starting with 2 or 3 is a landline, and sign-up platforms rarely accept one. |
Physical SIMs can sign up without issues.
Carriers & prefixes
Mobile prefixes by carrier.
Number portability applies — a prefix only shows the original carrier.
Porting rules in full
You keep your number when you switch. Nkom's principles: the new provider must first obtain the customer's written authorisation; the port must be done in as short a time as possible; the old provider may not block or delay it over money the customer owes; and the old provider may not use porting information for win-back marketing. The detailed rules are in chapter 4 of the ekomforskriften, and all provider-to-provider traffic goes through the national reference database, NRDB.
One thing worth knowing: Nkom used to run an official lookup called “Finn tilbyderen” that told you which provider a number was on. It has been taken out of service — the reason Nkom gives on the page is misuse, or use beyond its original consumer purpose. So Norway has no public lookup today, and the prefix doesn't identify the operator either.
User share comes from Nkom (the Norwegian Communications Authority), as of 2025-12. It shows how widely each operator is used — not how good its signal or service is. Official data →
