UPI is a unique method of identifying land parcels (lot) derived from a combination of finely grounded parcels of State,  District/ Jajahan/ Division/ Sub-District/ Jajahan kecil, County/ City/ Town/ Land/ Town District/ Desa, Seksyen/ Precint/ Block/ Section/ Village/ Island and lot/ Grant. The UPI application can display spatial and textual information for finely tuned landscapes and landmarks.

The app was developed in 2008 and is being upgraded in 2016 to enable all government agencies to adopt code standards and domain names.

The use of a standard UPI ensures that data sharing between agencies is successfully implemented.
