Kolkata District PIN Code Directory West Bengal

Kolkata is one of the districts in West Bengal, and like every district in India, it has its own postal network built around a Head Post Office that anchors the system. Every letter, parcel, or registered document that enters or leaves this district passes through that sorting point before reaching its final destination.

This page lists every post office in Kolkata — from the Head Post Office in the district headquarters to the smallest Branch Office in a remote village. Each entry links to its own detail page, where you'll find the complete postal profile: PIN code, office type, taluk, division, delivery status, and the parent offices it reports to.

If you need the PIN code for a specific locality, use the search bar above or browse the list below. For administrative purposes — court filings, bank account openings, or address proofs — always use the PIN code of the delivery post office that serves your exact location, not the general district headquarters code.

Postal Administration in Kolkata

Kolkata district falls under the {Postal_Division} Postal Division, which is part of the {Postal_Region} Region within the {Postal_Circle} Postal Circle. Day-to-day postal administration for the district is anchored by the Head Post Office at the district headquarters, with several Sub-Offices managing groups of Branch Offices across the various tehsils and revenue blocks.

India Post divides post offices into three functional types in Kolkata:

Head Post Office (HO): The district's primary postal facility. This is where bulk mail sorting for the district takes place, where treasury functions are handled, and where appeals and complaints for the entire district postal system are routed. There is generally one HO per district.

Sub-Office (SO): Sub-Offices serve as secondary hubs for towns and larger settlements. They offer the full range of postal services — Speed Post, registered mail, savings schemes, passport collection, and bill payment — and they manage the Branch Offices within their jurisdiction.

Branch Office (BO): The grassroots unit of the postal network. Branch Offices in Kolkata handle basic mail delivery, money orders, and simple savings transactions. Most rural residents interact primarily with their local BO, often staffed by a Grameen Dak Sevak (GDS) employee.

How to Read a PIN Code in Kolkata

All PIN codes assigned to post offices in Kolkata share the same first three digits, which represent the sorting district. When mail arrives at the state sorting hub, those three digits route it directly to the Kolkata area. The remaining three digits then identify the specific delivery office within the district.

This is why two post offices in the same district can have very similar-looking PIN codes — they share a sorting district prefix but differ in their delivery office suffix. And it's why using the correct full 6-digit code matters: the last three digits are what separates your neighbourhood from the one next to it.
