What is India Post DigiPIN?
DigiPIN (Digital Postal Index Number) is India's National Level Digital Addressing Grid developed by the Department of Posts in collaboration with IIT Hyderabad and ISRO (National Remote Sensing Centre). Unlike traditional 6-digit PIN codes that cover wide pin-code zones of several kilometers, DigiPIN provides hyper-local doorstep accuracy:
- 4m × 4m Grid Precision: Divides the entire Indian landmass and maritime zone into uniform 4-meter by 4-meter units.
- 10-Character Alphanumeric Code: Uses a strict set of 16 unambiguous characters (
2, 3, 4, 5, 6, 7, 8, 9, C, F, J, K, L, M, P, T) avoiding confusing letters like 0/O and 1/I. - 100% Offline & Permanent: Pure mathematical coordinate projection that works without third-party proprietary server tracking.
Comparison: Traditional PIN Code vs DigiPIN
