How do I find someone's phone number in Norway?

Directory search, reverse lookup and how Norwegian numbers are built.

Answered at: Checked at:

Short answer

You can find someone's phone number in Norway by searching their name or address on Gulesider, a directory of people and companies. You can also search a number there to see who it belongs to, and a section called Hvem ringte? ('Who called?') covers unknown callers. Norwegian mobile numbers have eight digits and start with 4 or 9.

Why

  1. Gulesider describes its service as finding phone numbers and addresses for companies and people.
  2. The Gulesider search box accepts a company, service, person, address or phone number.
  3. Nkom's numbering plan gives Norwegian mobile numbers eight digits in the ranges starting with 40–49 and 90–99.

Details

Gulesider is published by Gule Sider AS, which is part of Eniro Group. Fixed-line numbers in Norway also have eight digits, for example in the range starting with 20–39, so the first digits tell you whether a number is a mobile. Norway's country code is 47, so a number shown as +47 is Norwegian.

Tip

If an unknown Norwegian number calls you, search it on Gulesider before you call back.
