🏡 Understanding Italian Property Codes: Foglio, Particella & Subalterno
Every property registered in the Catasto (Italian Land Registry) is identified by three essential codes:
📘 Foglio (Map Sheet) → divides the municipality’s area into sheets
📗 Particella (Parcel) → identifies the specific land unit
📙 Subalterno (Subunit) → identifies the individual portion of the parcel, such as an apartment within a building
Together, they create your property’s unique cadastral identity — essential when verifying ownership, checking boundaries, or preparing contracts.
✨ Understanding these codes will help you read Italian documents with confidence and avoid common mistakes when buying property.
