Understanding postal coverage in Siwan, Bihar

Siwan district runs 265 post offices across 45 PIN codes, all routing up to the Siwan head post office at PIN code 841226.

The Siwan head post office, on PIN code 841226, is the point everything in this western Bihar district ties back to. From the town it serves outward to thirteen talukas, and every sub office and village counter feeds its mail up through that head office before anything leaves for the wider network. It is the anchor, and it shows in how the district is organised.

Across Siwan there are 265 post offices in total, spread over 45 PIN codes. One of those is the head office, 32 are sub post offices offering fuller counter services, and the remaining 232 are branch offices working out of smaller towns and villages. That branch share, close to nine in ten offices, tells you most of this district’s postal work happens in rural settlements rather than at big urban counters.

The Siwan taluka clearly dominates. It carries 119 offices on its own, far more than any other area, and the widest range of PIN codes in the district. Beyond it, the Mairwa area, Barharia and the Ziradei belt each run a smaller cluster of their own. You will see offices in towns such as Basantpur, Mairwa and Andar, and in villages like Sirsian, Bhikhampur and Madhopur where the branch office handles the day’s post for the whole neighbourhood. The complete list by area is in the Siwan taluka directory and the broader Bihar post office hub.

Because branch offices make up so much of the network, a word on timings: village counters often keep limited hours and many open around nine in the morning, so it pays to post early rather than leave it to the end of the day. Sub and head offices stay open longer and handle the heavier transactions.

Sending something time-bound out of Siwan usually means Speed Post or a tracked parcel, and the head and sub offices book both. Work out the likely cost on the Speed Post charge calculator before you go, check the right code with the PIN code finder for Indian post offices, or browse the Araria district directory for another district in Bihar. After booking, track your India Post item here using the receipt number.
