In India, the six-digit code used in the postal code system is called the Postal Index Number (PIN) . The first digit of a PIN indicates the zone, the second indicates the sub-zone, and the third, combined with the first two, indicates the sorting district within that zone. The final three digits are assigned to individual post offices within the sorting district. There are nine postal zones in India, including eight regional zones and one functional zone for the Indian Army.

Since India has separate PIN codes for different states, there is no single zip code for the entire country. To find the PIN code for a specific location in India, you can use a PIN code search engine or an interactive map of zip codes.
