Verifying against the live site and live WHOIS/DNS…
Common questions
Is nb.no legit or a scam?
AboutUs doesn't label sites "legit" or "a scam": this page lists the dated registration, DNS, HTTPS, mail-authentication and safety checks we could verify, each with its source, so you can decide for yourself.
Who owns nb.no?
Nobody has completed AboutUs's owner verification for nb.no. That's true of most sites here — it isn't itself a warning sign.
