Postal codes in Finland

Finland has used five-digit numeric postal codes since the 1970s. The first and second digits designate the general area of the municipality of the address, while the last three designate a smaller region within that larger area. The numeric postal code is usually accompanied by a written name for the smaller region.^[1]
