When searching for postal information on AreaPincodes.com, you may often come across terms such as HO, SO, or BO next to a PIN code. These abbreviations refer to different types of post offices under the India Post network. Understanding this hierarchy is essential if you use postal services regularly—whether for mail delivery, Speed Post, savings schemes, or e-commerce shipments.
India has one of the largest postal networks in the world, serving both densely populated cities and remote rural villages. To manage this vast system efficiently, India Post follows a structured hierarchy of post offices. This article explains the meaning, role, and importance of Head Offices (HO), Sub Offices (SO), and Branch Offices (BO) in simple terms.
Overview of the India Post Office Hierarchy
India Post operates through a three-tier structure:
- Head Post Office (HO) – Administrative and financial control center
- Sub Post Office (SO) – Urban and semi-urban service centers
- Branch Post Office (BO) – Rural-level delivery points
Each level plays a specific role in ensuring accurate mail routing, financial services, and last-mile delivery.
1. Head Post Office (HO)
What Is a Head Post Office?
A Head Post Office (HO) is the main administrative office for a defined geographical area, usually a district or a large city zone. It functions as the central hub for multiple Sub and Branch Post Offices.
Key Responsibilities of a Head Office
- Acts as the main accounting authority
- Handles high-volume mail sorting and dispatch
- Manages financial consolidation for subordinate offices
- Oversees postal savings schemes and government services
Services Available at a Head Post Office
- Speed Post and Registered Post
- Postal Savings Bank (SB, RD, TD, MIS, SCSS)
- Money Orders and India Post Payments Bank services
- Parcel and logistics services
- Administrative oversight of SOs and BOs
PIN Code Identification
Most Head Offices end with “HO” in official records. Many district-level PIN codes are assigned to Head Post Offices.
2. Sub Post Office (SO)
What Is a Sub Post Office?
A Sub Post Office (SO) operates under a Head Office and is commonly found in towns, cities, and urban neighborhoods. These offices serve as the primary interface for the public in populated areas.
Key Functions of a Sub Office
- Provides almost all postal services
- Acts as an account office for Branch Post Offices
- Handles daily customer transactions
Services Offered at Sub Post Offices
- Speed Post, Registered Post, and Parcel booking
- Savings Bank accounts and recurring deposits
- Money Orders and bill payments

PIN Code Identification
Most urban PIN codes belong to Sub Offices (SO). When searching on AreaPincodes.com, you’ll frequently see “SO” listed next to city-area PIN codes.
3. Branch Post Office (BO)
What Is a Branch Post Office?
A Branch Post Office (BO) is the most common type of post office in rural India. It serves villages and remote areas where establishing a full-fledged post office is not feasible.
Key Characteristics of Branch Offices
- Operate under a designated Account Office (SO or HO)
- Usually managed by a Branch Postmaster (BPM)
- Limited working hours compared to urban offices
Services Provided by Branch Offices
- Delivery of letters and parcels
- Basic savings schemes
- Money Order services (limited)

PIN Code Identification
Many village PIN codes are linked to BOs. These PIN codes are essential for ensuring correct rural delivery.
HO vs SO vs BO: Key Differences at a Glance
| Feature | Head Office (HO) | Sub Office (SO) | Branch Office (BO) |
|---|---|---|---|
| Location | Major cities / districts | Towns & urban areas | Rural villages |
| Authority | Highest | Medium | Basic |
| Services | Full range | Nearly full | Limited |

Why Understanding Post Office Types Matters
1. Accurate Addressing
Knowing whether your area falls under an HO, SO, or BO helps ensure correct addressing, reducing delivery delays.
2. Faster E-Commerce Deliveries
Online platforms like Amazon and Flipkart rely heavily on accurate PIN code mapping. Misidentifying a BO as an SO can affect delivery timelines.
3. Banking and Savings Services
Certain financial services are available only at HO or SO levels. Knowing your nearest eligible office saves time and effort.
4. Government Schemes and Benefits
Many welfare schemes are routed through post offices. Understanding the hierarchy helps you access services efficiently.

Most BOs do not book Speed Post directly. Parcels are routed through the associated SO or HO.
Do all PIN codes belong to a Head Office?
No. Many PIN codes belong to Sub Offices or Branch Offices, depending on the area.
