A postal code is optional in Costa Rica 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, Costa Rica's postal service publishes an official finder: correos.go.cr/codigo-postal. It is authoritative and kept current, which third-party copies often are not.
