Allocation of provider code for number portability

Providers who use 5-digit, 8-digit or 12-digit numbers or standardised special numbers shall release the number to the other provider to which the end user requests the number to be migrated. To implement the porting process, the various providers must be identified using a provider code.

Number portability between providers is implemented in accordance with the specifications in the reports “Forslag til tekniske løsninger for innføring av nummerportabilitet i Norge for geografiske og stedsuavhengige nummer” [Proposed technical solutions for the introduction of number portability in Norway for geographic and location-independent numbers] and “Technical specification for Number Portability for geographic and non-geographic numbers in Norway”. These reports state that the address information to be exchanged through the interface between different networks must include, among other things, a provider code that identifies the recipient provider/network. The structure of the provider code is described in section 8.2.3 of “Forslag til tekniske løsninger for innføring av nummerportabilitet i Norge for geografiske og stedsuavhengige nummer” [Proposed technical solutions for the introduction of number portability in Norway for geographic and location-independent numbers] and in sections 7.1.1, 7.1.2 and 11.2 of “Technical specification for Number Portability for geographic and non-geographic numbers in Norway”. The provider code will be allocated by the Norwegian Post and Telecommunications Authority.

Providers must submit an application to the Norwegian Communications Authority (Nkom) for the allocation of provider codes for number portability. The application must contain the following information:

  • name, address and organisation number of the provider,
  • name of contact person,
  • telephone number, fax number and e-mail address,
  • information about the types of number for which the prefix will be used (fixed network or mobile).

Applications can be sent to firmapost@nkom.no.
