← All post offices in Siwan districtA guide to post offices in Siwan
Siwan taluka runs 119 post offices over 22 PIN codes, mostly village branch offices, with the Siwan head office above them.
Most of Siwan’s postal reach comes from its village counters. The taluka has 119 offices in total, of which 105 are branch offices and 13 are sub offices, all working under the Siwan head office (841226). With branch offices making up the large majority, this is a network built to carry mail out to scattered settlements rather than concentrate it in one town centre.
The 22 PIN codes cover the spread, with the town side running through 841226, 841227 and 841228, and the further reaches under 841203 and 841235. Town points like Basantpur, Chainpur and Gaushalaroad are where you will find a fuller counter, while villages such as Hussepur, Sekhpura and Mohamda rely on their nearest branch office.
One thing worth keeping in mind: the branch offices run short hours and a single counter, so it pays to post in the morning rather than leave it late. They take Registered Post and EMS, but anything bulky or urgent moves more reliably through a sub office. The PIN code finder will confirm which code an address belongs to.
Because there are only 13 sub offices against 105 branches, those sub offices carry most of the heavier counter work and act as the step between a village branch and the Siwan head office. A registered article posted at a small branch usually travels up to a sub office and then to Siwan before it leaves the taluka, so morning timing matters if you want it moving the same day.
