What Is Bo in Post Office

If you’ve noticed “BO” in your post‑tracking status, you might be wondering what it means. In simple terms, BO stands for Branch Office in the post office system. Understanding this term helps you track your mail better and know exactly where your parcel or letter is in the delivery process.

What is a BO (Branch Office)?
A BO is a smaller unit of India Post under a bigger post office. It works under a Sub Office (SO) or Head Office (HO). 

For example: Village X has a BO that deals with daily mail and savings bank deposits but sends bigger parcels to the SO.

Quick‑tip bullet list: BO key features

• It offers basic postal services: letter mail, registered mail, small savings.  
   
• It is under the account of an SO or HO (so doesn’t have full independent status).
   
• It often has shorter working hours compared to bigger offices.  
   
• Money orders and big parcel booking may still go via the account office. 
   
• Useful in rural or remote areas: quickly accessible for basic services.
   

Here’s an example
Suppose you live in Village Z. A parcel you send is “Dispatched to BO” on day 1. That means it reached your local branch office. On day 2 you get delivery from that BO. So “BO” in your tracking means the branch office responsible for your area.

Why knowing BO matters
When you track a parcel and it shows BO, you know it’s reached your local unit. If you don’t get delivery next day, you may visit the BO or call them. It helps reduce confusion about status messages.
