Pin code is a 6 digit number used to identify post offices in India. PIN stands for Postal Index Number, introduced by the Indian postal department to simplify mail sorting across the country.

India introduced the PIN code system on 15 August 1972. With 36 states and union territories, many places across India share the same name — even within the same district. A unique 6-digit number assigned to each post office solved this problem and made mail delivery far more reliable.
Our database covers pin code details of over 1,54,700 post offices, including their location, district, state, taluk, and how they connect to other offices in the postal network.
Each pin code is made up of 6 digits. The first digit represents one of 9 postal zones in India (8 geographic zones + 1 for the army postal service). The second digit narrows it to a sub-region, the third to a sorting district, and the last three digits identify the specific delivery post office.
