About Italy Postal System

Poste Italiane administers the Codice di Avviamento Postale (CAP), a five-digit numeric system established in 1967 to modernize mail distribution across Italy's 20 regions. The framework is designed to handle the logistical complexities of Italy’s historic city centers and mountainous terrain. Accurate CAP data is a prerequisite for efficient commercial routing and public administration throughout the Mediterranean peninsula.
