Mairwa taluka in Siwan has 23 post offices under 4 PIN codes, made up of 2 sub offices and 21 village branch offices.
For a small taluka, Mairwa keeps a lot of counters open. There are 23 post offices here, but the structure is lopsided: just 2 sub offices, with 21 branch offices carrying the rest of the work out into the villages. Four PIN codes tie the whole area together.
The town of Mairwa and the smaller settlement of Tarwara hold the main counters, while branch offices in places like Sirsian handle the routine post for the surrounding fields. Because so much of the network is branch-level, hours can be short and morning-heavy. If you are booking Speed Post or sending a parcel, the earlier you arrive the better your chances of it leaving the same day.
Mairwa does not have its own head office. Articles booked across the taluka are routed through the Siwan head office, then move into the wider sorting chain. The Siwan district directory lists every taluka, and the PIN code finder will confirm the exact code for a village. The working codes here include 841239, 841506 and 843108.
If you want to compare post offices in Mairwa with a sibling taluka such as Andar, the district hub links them side by side. Need to estimate postage first? Try the Speed Post calculator, then track your article once it is on its way.
