Maharajganj Pin Code Number - Post Office List

PIN stands for Postal Index Number - a 6-digit code India Post assigns to every post office, introduced in 1972 to sort and route mail without relying on handwritten place names alone.

The first digit marks one of 9 postal zones (regions) covering India. The first two digits together identify the sub-region/postal circle, the first three identify the sorting/revenue district within that zone, and the last three digits identify the individual post office.

Use the locator above: pick a State, then a District, then optionally the first letter of the post office name, and click Locate. Or type a PIN code, office name or district directly into the search box - it detects a 6-digit PIN automatically.

Yes - a single 6-digit PIN code is often shared by a main post office and several smaller branch offices serving the surrounding area, which is why search results can list multiple offices under the same code.

They mark the office's place in India Post's hierarchy, from largest to smallest: HO (Head Office) - the main office for a district; PO (Sub Post Office) - a mid-sized office; BO (Branch Office) - a smaller office typically serving a rural or local area.

A "Delivery" office delivers mail directly to addresses in its area; a "Non Delivery" office only handles mail for pickup or onward sorting and doesn't run its own delivery rounds.
