Postal services in the Principality of Monaco are operated by La Poste Monaco, which maintains a close technical partnership with the French postal system. The territory utilizes a five-digit numeric Code Postal that is integrated into the French numbering plan, specifically reserved for the Monegasque administration. This precise geographic identifier is critical for managing the high volume of premium mail and financial documents within the world's second-smallest nation.
The Monegasque Code Postal consists of five digits. The first three digits are always \"980\", which is the unique department-style identifier for Monaco, while the final two digits represent the specific district or sorting facility.
