Pin Code & Post Offices in Supaul district of Bihar

Every PIN Code is mapped exactly to one delivery post office which receives all the parcel to be delivered to one or more lower post offices within its jurisdiction, all of which share the same code. The delivery post office can be a General Post Office (GPO), a Head Office (HO), or a Sub-Office (SO) which are usually located in urban areas.

The parcel from the delivery post office is sorted and routed to other delivery post offices for a different PIN or to other related Sub-Offices or Branch Offices for the same PIN. Branch offices (BOs) are located in rural areas with limited postal services.
