A postal code is optional in Iceland addresses — mail is deliverable without one, though including it speeds up sorting.

Look up a specific address

For the code covering one particular street or building, Iceland's postal service publishes an official finder: posturinn.is. It is authoritative and kept current, which third-party copies often are not.
