Supported Number Types
Number Type | Format Example |
Geographic (Local) | e.g., +47 21, +47 23 |
National | e.g., 85 xxx xxx |
Toll-Free | e.g., 800 xxx xx |
Mobile numbers (+47 4xx or +47 9xx) are not portable to VoIP operators. If you already have a mobile number you would like to use for outbound calls on CloudTalk, we can create a Virtual Caller ID of your existing number
Required Porting Documents
The following applies to all Norwegian number types (local, national, toll-free):
Signed Letter of Authorization (LOA)
Must be completed and signed by an authorized representative
Information must exactly match the current provider's records

Latest Invoice from Your Current Provider

Should show the number(s) to be ported and the account holder’s name
Other Compliance Documents
In addition to porting documentation, Norwegian authorities require that businesses provide valid registration proof:
Brønnøysund Register Center (Brønnøysundregistrene) is the official Norwegian government registry for businesses. It maintains records of all legal entities registered in Norway, including their official name, address, and registration status.
To host a Norwegian number with CloudTalk, you must submit:
