Know Your DigiPIN Indian Post : DigiPIN India Post Digital Addressing

Posted on by Thomas Butler

DigiPIN is a new geo‑coded digital addressing system that divides India into ~4 m × 4 m grid cells, assigning each a unique 10-character alphanumeric code based on latitude and longitude.

Individuals can generate their DIGIPIN by visiting the official “Know Your DIGIPIN” portal (e.g., https://dac.indiapost.gov.in/mydigipin/home).

🧭 What is DIGIPIN?

  • DIGIPIN, which stands for Digital Postal Index Number, is a new digital addressing system launched by the Department of Posts, Government of India. It aims to revolutionize how locations are identified and services are delivered across the nation by providing a precise, geo-coded addressing system.

  • It provides precise location info within small areas (like a specific house), unlike the traditional six‑digit PIN Code that only covers wider regions.

  • Developed by the Department of Posts in collaboration with IIT Hyderabad and ISRO’s NRSC, and fully open-source.

Why DIGIPIN Matters 🧩

  • 🛵 Improved delivery: Enhances last-mile logistics for e-commerce and postal services.

  • 🚨 Better emergency response: Enables exact locations for ambulances, fire services, and police.

  • 🏞 Mapped everywhere: Works even in rural, remote, maritime, or forested areas lacking official addresses.

  • 🔐 Privacy‑preserving: Only uses geographic coordinates, with no personal data stored.

How to Get Your DIGIPIN 🔍

  1. Go to the “Know Your DIGIPIN” portal: dac.indiapost.gov.in/mydigipin/home

  2. Allow location (GPS/GNSS) access via your browser or device.

  3. Click to generate your 10-character code—automatically based on current coords.

  4. Optionally, manually enter lat‑long to look up a DIGIPIN, or paste a DIGIPIN to retrieve its location.

What DIGIPIN Doesn’t Do

  • ❌ It does not replace the existing six-digit PIN codes—it acts as an additional layer of precise address information.

  • It remains fully compatible with current addresses and postal systems.

Technical Overview

  • Each DIGIPIN maps to a ~4 m grid, encoding coordinates into a hierarchical alphanumeric code.

  • The full mapping logic and reference grid are hosted on GitHub (repo available via India Post).

Example in Action

A hypothetical DIGIPIN for The Indian Express office in Noida is 39J‑53M‑TJF9, representing its precise location within a 4 m × 4 m grid.

✅ Summary

  • What: DIGIPIN is a 10-character digital address representing ~4 m grids across India.

  • Why: It offers ultra-precise location data—boosting delivery efficiency and emergency services—while preserving privacy.

  • How: Visit the portal, enable location, click to generate your code (or manually input coordinates).

  • Note: It complements but doesn’t replace traditional PIN codes.
