Find Any PIN Code in India — Every Post Office, Every District

India has over 1,65,000 post offices spread across 28 states, 8 union territories, hundreds of districts, and thousands of villages. Finding the right 6-digit PIN code for any one of them — quickly and with confidence — is exactly what this directory is built for.

We cover every post office in the country: Head Offices in state capitals, Sub-Offices in town centres, and Branch Offices tucked away in villages that won't appear on most maps. Every listing includes the full PIN code plus the details that actually matter — office type, delivery status, postal circle, and the Taluk it falls under.

What Is a PIN Code and Why Does It Matter?

PIN stands for Postal Index Number. It was introduced on 15 August 1972 to solve a real problem: India's enormous geographic spread, dozens of official languages, and hundreds of identically named localities made routing mail by hand unreliable and slow.

The solution was elegant. A simple 6-digit number that any sorting machine — or any postal worker — could read the same way, regardless of language or region. That system has been in continuous use for over 50 years and is more important today than it ever was.

Getting your PIN code wrong used to mean a delayed letter. In 2026, the consequences are broader:

• E-commerce orderson Amazon, Flipkart, Meesho, or Zepto may show "not serviceable" if the PIN code doesn't match the actual delivery zone — even if a courier does serve your area.
• Bank account opening and KYC(Know Your Customer) verification requires an address PIN code that matches the one on your ID documents. A mismatch can freeze the process.
• GST registrationfor businesses mandates a correct postal address with a valid PIN. An error can trigger a tax mismatch on returns.
• Aadhaar-linked government schemes — including DBT (Direct Benefit Transfer) subsidies — use PIN codes to verify geographic eligibility. The wrong code can mean you're excluded from a scheme you qualify for.
• Credit scoring and fintech platforms increasingly use PIN codes to assess regional risk profiles during loan applications.

This directory exists so you always have the exact code — not a nearby area's code, not an outdated one, but the precise 6-digit number assigned by India Post to your specific locality.

How to Read a 6-Digit PIN Code

Every PIN code is a routing instruction in disguise. Each digit carries specific information about where a piece of mail needs to go. Once you understand the structure, any PIN code becomes readable at a glance.

Here is what each digit means:

Digit 1 — The Postal Zone India is divided into nine postal zones. The first digit tells you which one. Zones 1 through 8 are geographic, covering different parts of the country. Zone 9 is reserved exclusively for the Army Postal Service (APS).

Digit 2 — The Postal Circle The second digit narrows it down to the postal circle, which in most cases corresponds to a state or group of states. For example, "46" at the start of a PIN places it in the Madhya Pradesh Postal Circle.

Digit 3 — The Sorting District This digit routes the mail to the correct sorting hub within the circle. Automated sorting machines at regional distribution centres read this digit to decide which onward route the mail takes.

Digits 4, 5, and 6 — The Delivery Post OfficeThe last three digits identify the exact post office responsible for delivering to that address. This is the most granular level of the system.

A Real Example: PIN Code 464221

Breaking this down:

• 4 → Zone 4 (Maharashtra, Madhya Pradesh, Goa, Chhattisgarh)
• 46 → Madhya Pradesh Postal Circle
• 464 → Vidisha Sorting District
• 221 → Ganjbasoda Sub-Office, Basoda Taluk

What looks like a random six-digit number is actually a precise set of routing instructions embedded in a single string. Every PIN code in India works this way.

India's 9 Postal Zones — Complete List

The first digit of any PIN code places it in one of these nine zones:

Zone - States and Union Territories Covered

Zone 1 Delhi, Haryana, Punjab, Himachal Pradesh, Jammu & Kashmir, Ladakh

Zone 2 Uttar Pradesh, Uttarakhand

Zone 3 Rajasthan, Gujarat, Daman & Diu, Dadra & Nagar Haveli

Zone 4 Maharashtra, Goa, Madhya Pradesh, Chhattisgarh

Zone 5 Andhra Pradesh, Telangana, Karnataka

Zone 6 Tamil Nadu, Kerala, Puducherry, Lakshadweep

Zone 7 West Bengal, Odisha, Assam and the North Eastern states

Zone 8 Bihar, Jharkhand

Zone 9 Army Postal Service (APS) — not used by civilians

If you know which zone your state falls in, you already know what the first digit of your PIN code should be. A PIN for Chennai will always start with 6. A PIN for Lucknow will always start with 2. This built-in logic makes it easy to spot a clearly incorrect code before it causes problems.

Types of Post Offices in India — and What Each One Does

Not all post offices offer the same services. The directory indicates the office type for every listing, because this affects what you can actually do there.

Head Post Office (HO)

The Head Post Office is the administrative and accounting hub for an entire postal division — typically covering a full district or a major city. HOs handle the full range of services including international mail, speed post, registered post for high-value items, and foreign currency money orders. If you need to escalate a complaint or track a consignment that has gone missing, the Head Post Office is where you start.

Sub-Post Office (SO)

Sub-Offices report to a Head Post Office and serve the surrounding town or cluster of localities. They offer most of the services available at an HO — speed post, savings accounts, insurance, and bill payment — but may not handle international dispatch directly. Each Sub-Office oversees a group of Branch Offices in the area around it.

Branch Post Office (BO)

Branch Offices are the smallest unit in India Post's network. They are often the only postal infrastructure in a rural village, and many operate out of a single room with limited staff. Services may be restricted to basic mail, savings deposits, and money orders — but their delivery reach into surrounding hamlets and farm communities is wide. For many rural Indians, the local Branch Office is their primary point of contact with both the postal system and basic financial services.

Delivery vs. Non-Delivery Offices

Within each office type, there is a further distinction:

A delivery office is responsible for the physical last-mile drop-off of letters, parcels, and registered mail to doorsteps in its area. When your tracking update says "Out for Delivery," it means a delivery office has dispatched your item.

A non-delivery office accepts mail for booking and forwards it onward but does not itself deliver to doors. If your parcel is routed through a non-delivery Sub-Office, it will be handed off to the appropriate delivery office before it reaches you. This is worth knowing when tracking a time-sensitive consignment.

What This Directory Includes for Every Post Office

Each listing in this directory goes beyond the PIN code itself. Here is what you will find for every post office:

Office Type —HO, SO, or BO, so you know what services to expect before visiting.

Delivery Status —Whether the office handles doorstep delivery or is a booking/forwarding office only.

Postal Hierarchy — The full chain: Postal Circle → Postal Region → Postal Division → Parent Head Office. This is the escalation path if you need to resolve a complaint or verify a high-value shipment.

Taluk / Tehsil — The administrative block the post office falls under. This is essential for distinguishing between similarly named offices in different parts of the same district, which is a very common issue in rural India.

Circle and District — So you can navigate from the state level all the way down to an individual branch.

How Our Data Is Kept Current

This directory is synced with the

India Post Open Government Data (OGD)

platform, the official source used by India Post itself. Whenever a new locality is added, a postal division is reorganised, or a district is bifurcated and its post offices reassigned, we update accordingly.

The 2026 edition of this directory reflects all administrative changes notified by India Post through the current year. This includes new districts carved out of older ones, renamed localities, and postal circles that have been reorganised following state-level administrative changes.

If you are using a PIN code for a formal purpose — GST registration, bank KYC, or a government form — and want a secondary confirmation, the India Post website at

indiapost.gov.in is the primary government source. The codes in this directory are sourced from the same underlying data.
