Watch the leading zero

Some Norway postal codes begin with a zero, such as 0001. Spreadsheets and some web forms silently drop it, turning 0001 into 1 — which is either a different place or not a valid code at all. Format the column as text before pasting codes into a spreadsheet.

A postal code is required in a complete Norway address.

Look up a specific address

For the code covering one particular street or building, Norway's postal service publishes an official finder: adressesok.posten.no/nb/postal_codes/search. It is authoritative and kept current, which third-party copies often are not.
