[JorgenLjones]

Torbjørn: I'm not familiar with that library, but this is what stands out to me at first glance.

https://github.com/navikt/fnrvalidator

• Author: NAV
• Private or public sector author: Public I* s it the main fork of the repo: Yes
• Is it actively maintained: Yes, has 400+ commits and last commit was 14 days ago
• Key features: Supports SSN types FNR, DNR and HNR and gives one or more reasons if an SSN is invalid

https://www.npmjs.com/package/@ssfbank/norwegian-id-validators

• Author: an npm org named @ssfbank
• Private or public sector author: Private
• Is it the main fork of the repo: No, it is a fork of https://github.com/storbukas/norsk-validator and that repo has many commits that are not in the ssfbank fork Is it actively maintained: Maybe not, has only 2 commits and last commit was 2 years ago
• Key features: Supports account numbers, KID, SSN (possibly only of type FNR), organization numbers

All in all, for validating SSNs specifically I would recommend using NAV's library.
