Verified answers regarding the Indian postal index numbering system.
PIN stands for Postal Index Number. It is a 6-digit numeric code introduced by India Post on 15 August 1972 to simplify the sorting and delivery of mail across India.
An Indian PIN code has exactly 6 digits. The 1st digit indicates the postal region, the 2nd indicates the sub-region, the 3rd indicates the sorting district, and the last 3 digits represent the specific delivery post office.
You can use the universal search bar on our homepage by entering your locality name, post office name, district, or city, or browse through the State and District directory.
Yes. In many urban and rural areas, multiple branch post offices (BO) or sub post offices (SO) share the same 6-digit PIN code under a single delivery sorting office.
You can cross-reference any PIN code on India Post's official lookup portal at indiapost.gov.in. We also provide direct verification links on every PIN code and post office page.
Delivery status indicates whether a post office handles physical mail and parcel delivery to addresses. "Delivery" offices deliver mail directly, whereas "Non-Delivery" offices only accept mail and provide counter services.
