Vatican City Address Format
Vatican addresses follow the Italian format: recipient, street and house number, then the postal code followed by the locality (Città del Vaticano) on one line, then the country. The whole state is one locality with a single postal code (00120), so there are no provinces or districts. For inbound international mail, 'Vatican City' on the last line is essential — mail addressed as Rome, Italy may still arrive but should not be relied on.
