Postal codes in Finland
Finland has used five-digit numeric postal codes since 1971. The first two digits designate the municipality or group of municipal small communities where it may be 5; codes ending in 1 are for post office boxes. A corporation receiving large amounts of mail may have its own postal code. The special postal code 99999 is for Korvatunturi, the place where Santa Claus (or Joulupukki in Finnish) is said to live.
