India PIN Code & Post Office Directory

India PIN Code Directory

India's postal network is one of the largest in the world, and finding the right 6-digit PIN code can make the difference between a parcel reaching its destination on time or getting lost somewhere in the sorting chain. This directory covers every state, every district, and every post office — from Head Offices in state capitals to Branch Offices in villages that don't even appear on most maps.

We pull our data from the India Post Open Government Data platform and keep it in sync with the latest postal circle updates. If a new locality has been carved out, a division reorganised, or a district renamed, we update accordingly. The 2026 edition reflects all administrative changes notified by India Post up to the current year.

Use the search bar above to look up by state, district, or post office name. Or browse through the state-wise list below — each state page breaks down every district, and each district page lists every individual post office with its office type, delivery status, and parent circle details.

How PIN Codes Work in India

The Postal Index Number was introduced on August 15, 1972, and its logic has remained unchanged since. Each 6-digit code carries four layers of information baked right in.

The first digit tells you the broad postal zone — India is divided into nine of them, eight geographic and one reserved for the Army Postal Service. The second digit narrows it down to the specific postal circle, which in most cases maps to a state. The third digit is the sorting district — it tells the automated sorting machines at regional hubs where to route the mail next. The final three digits identify the exact delivery post office.

So a code like 464221 isn't just a random number. The 4 places it in Zone 4 (Maharashtra, MP, Goa, Chhattisgarh). The 46 tells you it's the Madhya Pradesh Postal Circle. The 464 routes it to the Vidisha sorting district. The 221 lands it at Ganjbasoda Sub-Office jurisdiction in Basoda Taluk.

Once you understand this structure, reading a PIN code becomes almost intuitive.

Why the Right PIN Code Matters More Than Ever

Getting the PIN code wrong used to mean a delayed letter. Today it has broader consequences. E-commerce platforms like Amazon and Flipkart use the PIN code to determine whether a location is serviceable, which courier to assign, and what the delivery timeline will be.

Banks and insurance companies use it as part of KYC verification. GST registration requires a valid postal address with a matching PIN. And Aadhaar-linked services use it to confirm geographic eligibility for certain government schemes.

For businesses, an incorrect PIN on an invoice can trigger a GST mismatch. For individuals, it can stall a bank account opening or delay a government document. This directory exists to make sure you always have the correct code — not an approximation, not a nearby neighbourhood's code, but the exact 6-digit number assigned by India Post to your specific locality.
