Standardizing geo-coded addresses for efficient public service delivery and logistics across India.
India Post, in collaboration with IIT Hyderabad, NRSC and ISRO, has introduced DIGIPIN – a geo-coded addressing system designed to assign a unique digital identity to every 4m x 4m area across the country.
DIGIPIN uses a 10-digit alphanumeric code derived from lat-long coordinates. The system divides India into a grid using 16 unique characters (2–9, C, J, K, L, M, P, F, T), enabling hierarchical encoding.
Each character in the code represents one level of precision, identifying a 4m x 4m area at the 10th level of granularity.
The DIGIPIN layer is the cornerstone of the entire digital address ecosystem. DIGIPIN is visualised as an alphanumeric offline grid system that divides the geographical territory of India into uniform 4-meter by 4-meter (approx.) units. Each of these units is assigned a unique 10-digit alphanumeric code derived from the latitude and longitude coordinates. This code acts as an offline reference to pinpoint any location. The system is scalable, GIS-compatible, and supports integration into multiple applications.
DIGIPIN layer functions as a logical, offline address referencing mechanism, ideal for locating areas during emergencies, logistics workflows, and disaster response. It’s a public system with no privacy issues, as no personal data is stored.
The DIGIPIN code is derived from geographical coordinates and uses 16 alphanumeric characters: 2, 3, 4, 5, 6, 7, 8, 9, C, J, K, L, M, P, F, T. Encoding follows a 10-level hierarchy.
The bounding box used spans from longitude 63.5° to 99.5° east, and latitude 2.5° to 38.5° north, based on the EPSG:4326 coordinate reference system (WGS84). It includes India’s entire land mass and maritime zones like the EEZ, making the system useful even for sea-based operations.
