San Marino Address Format
San Marino follows the Italian addressing style: recipient, street name + house number, then the 5-digit CAP followed by the locality (castello) name, then the country. The castello is not written as a separate region line because the CAP already encodes it. Mail is handled by Poste San Marino, not Poste Italiane.
