India Post Offices in Kolkata, West Bengal

The Alipore head post office, under PIN 700027, sits at the centre of Kolkata’s postal arrangement and gives the city’s network its anchor point. Working outward from it, the district is covered by 154 India Post offices spread across 59 PIN codes. The sub and branch offices around the city report up to Alipore, which keeps sorting and dispatch tied to one central hierarchy rather than scattered across many heads.

Unlike most districts, Kolkata is treated as a single area on the postal map, so coverage is about depth within the city rather than reach across far-flung talukas. Of the 154 offices, 6 are head offices and 139 are sub post offices, with only a handful of branch offices in the mix. That balance means most counters you walk into are full-service sub or head offices, where you can do registered work, savings transactions and parcel booking at one window instead of being sent elsewhere. Counter hours vary from one office to the next, though most open around ten in the morning, so a quick check before you set out saves a wasted trip.

The PIN codes run almost entirely through the 700 series. Central neighbourhoods sit under early codes like 700001, 700002 and 700005, while areas such as Bhawanipur and Alipore carry their own numbers further along the range. If you’re posting to an unfamiliar part of the city and aren’t sure of the exact code, the PIN code finder will sort it out in a few seconds, and the West Bengal post office hub lets you compare Kolkata with neighbouring districts like Bankura.

Speed Post and parcel booking are the busiest services across the post offices in Kolkata, given how much commercial and personal mail leaves the city every day. You can check rates on the Speed Post calculator before booking, and the full Kolkata office list shows addresses and timings for each counter.
