About India Pincode System
The Postal Index Number (PIN), commonly known as a pincode, is a 6-digit numerical code used by India Post to identify delivery post offices. Introduced in 1972, the PIN code system was designed by Shriram Bhikaji Velankar to simplify and automate mail sorting.
How Does the Pincode System Work?
Each pincode consists of 6 digits that encode specific geographic information. The first digit represents one of nine postal zones in India. The second digit, together with the first, indicates the sub-zone (state or union territory). The third digit represents the sorting district. The last three digits identify the individual delivery post office within that sorting district.
