India has relied on the Postal Index Number (PIN) system since 1972 to streamline mail delivery. The traditional PIN code (six digits) groups are addressed by region and post office, which, while effective for postal sorting, lacks fine-grained location detail. In an era of e-commerce and rapid response needs, the government saw the need for more precise digital addresses.
Enter DIGIPIN (Digital Postal Index Number) – a 10-character alphanumeric code pinpointing a specific 4m x 4m location. Launched by the Department of Posts in collaboration with IIT Hyderabad and ISRO’s NRSC, DIGIPIN adds a layer of geospatial accuracy on top of traditional addresses. Below, we delve into DIGIPIN’s features, its significance for governance and services, and how it fits into India’s broader digital and geospatial initiatives.
India Post launched a new digital address system called DIGIPIN in May 2025, assigning unique geocoded identifiers to locations across the country.
In August 2025, the Department of Posts signed an MoU with MapmyIndia (Mappls) to integrate DIGIPIN into indigenous mapping platforms, boosting its accessibility and adoption.
The collaboration aims to create a standardized digital addressing system benefiting millions and strengthening India’s digital infrastructure for service delivery.

DIGIPIN stands for Digital Postal Index Number, essentially a geo-coded digital address system introduced by India Post to improve location identification nationwide. Each DIGIPIN is a unique 10-character alphanumeric code that corresponds to a ~4×4 square meter grid on Indian territory. In effect, it is like giving every small plot of land – every house, building, or even spot in a remote field – its own permanent digital address.
Geospatial Encoding: The code is derived from the latitude and longitude of the location, encoded into a short string. It uses a grid-based system dividing India (including remote and maritime zones) into trillions of tiny blocks.
For example, a DIGIPIN might look like 39J4C3CPP3 (an alphanumeric mix) representing one specific 4m x 4m plot.
The encoding is such that geographical coordinates can be mathematically decoded from the DIGIPIN, and directional logic is built in (nearby codes share prefixes).
This ensures that the code is location specific and permanent , it won’t change even if administrative names (state, city, street) change.
Developed By:
The system’s technology was developed by the Department of Posts in collaboration with IIT Hyderabad and ISRO’s National Remote Sensing Centre (NRSC).
This multi-agency effort provided the algorithm and infrastructure for generating and managing the codes.
Relation to PIN Code:
DIGIPIN is not a replacement for the existing PIN code system, but a complementary layer.
Traditional PIN codes (6 digits) will continue for postal sorting and broader area identification (e.g., city or zone).
DIGIPIN, on the other hand, zooms into the doorstep level.

High Precision & Coverage: Each code pinpoints an exact location with 4-meter accuracy, far more granular than a locality-based PIN code. Urban slums, rural villages, hilly terrain, and even offshore installations (e.g. oil rigs in EEZ) can all be addressed by DIGIPIN. This universality ensures no place is “too remote” to have an address.
Open-Source & Interoperable: DIGIPIN’s underlying algorithm and data formats are open-source and published (the technical documentation and code are available on GitHub). This encourages collaboration and integration any ministry, state government, or even private app can integrate DIGIPIN into their systems without licensing hurdles.
Privacy-Focused: The code contains only location coordinates, no personal information. Unlike an address that might reveal someone’s name or house details, a DIGIPIN by itself is just a geocode. The system does not store personal data against the code essentially, it’s an algorithmic label for a spot on the earth.
Standardized Format: The code uses a restricted set of 16 alphanumeric characters at each position. The design ensures logical ordering – neighboring locations have similar prefixes, aiding manual use and memorability to an extent.
Address-as-a-Service (AaaS): DIGIPIN is envisioned as a foundational element of “Address-as-a-Service”. This means providing on-demand address data services for various applications.
To facilitate the adoption of DIGIPIN, the Department of Posts has launched user-friendly digital platforms and partnered with mapping services:
“Know Your DIGIPIN” Portal: A dedicated web application allows users to retrieve their DIGIPIN easily. By granting location access on a GPS-enabled device or by manually entering latitude/longitude, one can generate the exact DIGIPIN for their current location or any point on the map. The portal features an interactive map where users can zoom to their address and see the code, or conversely input a DIGIPIN to see the location.
“Know Your PIN Code” Geo-portal: Alongside DIGIPIN, the postal department introduced an upgraded Know Your PIN Code web application. This tool uses geospatial data to help users find the correct traditional 6-digit PIN code for any locality by using GPS/location data.
MapmyIndia Integration: To further popularize and embed DIGIPIN into everyday navigation, India Post partnered with MapmyIndia (Mappls), an indigenous mapping and GIS services company. Under the August 2025 MoU, MapmyIndia will integrate DIGIPIN into its Mappls app and services.
Usability and Feedback: Both the DIGIPIN and PIN code portals are designed to be interactive and user-centric. The Department of Posts has invited public feedback on these platforms to improve their accuracy and usability. Users can report if a location’s code seems off or if the interface is confusing. This participatory approach will help the system evolve.
DIGIPIN is more than just a tech upgrade for addresses – it carries wide-ranging significance for governance, economy, and society. Here are the key benefits and implications:
Precision in Deliveries and Services
E-commerce giants (Amazon, Flipkart, etc.) can deliver products more efficiently.
Reduces misdeliveries and the time couriers spend searching for addresses.
Enhanced Emergency Response
DIGIPIN provides a uniform way to communicate location to police, ambulance, and fire services.
Urban emergency responses (like firefighters finding a specific building entrance) also become more efficient with geocoded addresses.
In disaster management, relief teams can map affected households by DIGIPIN, coordinate logistics, and ensure aid reaches the exact locations needed.
Inclusion of Unaddressed Areas
India has many rural and remote regions where traditional addressing is inconsistent or nonexistent (e.g., tribal hamlets, hilly villages, or nomadic settlements).
DIGIPIN offers a digital identity to every location, no matter how off-grid. This can aid in rural development:
Government schemes (housing, LPG connections, banking via India Post) can be better targeted when even the remotest household has a reference code on the map.
Maritime zones are included too; DIGIPIN can assign addresses to offshore assets like oil platforms or research vessels (which was impossible with the PIN system). Thus, the system promotes geospatial inclusivity, ensuring no place is “off the map” anymore.
Governance and Planning
DIGIPIN is a building block for smarter governance. Accurate geospatial addressing can improve urban planning, land record management, and taxation.
City authorities can map properties by DIGIPIN for property tax collection or utilities provisioning, leading to better coverage and reducing overlaps/omissions.
It ties into projects like the National Geospatial Policy 2022 which aims for a geo-enabled economy. For example, mapping slums or encroachments with DIGIPIN could help formalize them and deliver services.
In land administration, DIGIPIN complements programs like ULPIN (Unique Land Parcel ID Number) – while ULPIN tags land parcels, DIGIPIN tags location points, together contributing to a robust digital cadastre.
Economic Boost and Innovation
Efficient addressing has direct economic benefits: studies indicate it can cut logistics costs (by reducing fuel use and delays) and boost trade.
A precise address system fosters entrepreneurship.
Government Push for Geospatial Technology
DIGIPIN is part of a larger effort to use geospatial technology for governance and development.
Union Budget 2025 announced a National Geospatial Mission to build foundational infrastructure.
Programs like NAKSHA (National Urban Land Survey) modernize urban land records using aerial surveys and GIS.
NAKSHA’s mapped coordinates can link directly to DIGIPIN codes, ensuring every surveyed plot has a digital address.
Policy Alignment
National Geospatial Policy, 2022
Deregulated and encouraged geospatial data use.
Envisions frameworks like a national address database.
DIGIPIN aligns with this by offering a crowdsourced digital address system.
Digital India Land Records Modernization Programme (DILRMP)
Digitizes land records and maps.
Land parcels receive ULPIN (Unique Land Parcel ID).
Addresses gain DIGIPIN.
Together, these form an integrated digital map for all assets (farmland, factories, etc.).
Interoperability and Technical Maintenance
Need for global system integration:
Most services use latitude/longitude or proprietary codes.
DIGIPIN aims for interoperability.
Open-source nature could allow integration into international platforms.
Technical tasks:
Maintaining coordinate grid accuracy.
Updating for datum changes.
Likely managed by India Post with ISRO’s support.
