A PIN (Postal Index Number) code is a 6-digit numeric postal code introduced by India Post on August 15, 1972, to streamline mail sorting and delivery nationwide. Spanning urban metropolises, industrial corridors, and remote rural hamlets, India Post operates one of the world's largest postal networks covering over 1,50,000 post offices.
Our comprehensive pincode directory lists 1,51,319 post offices across 631 cities and districts in India. Whether you need to verify a postal code for courier dispatch, e-commerce delivery, bank documentation, or postal savings schemes, this database allows instant searching by 6-digit pincode, office name, or locality.
Each digit in a 6-digit Indian pincode carries specific geographic significance. The first digit represents one of 9 postal zones across India (1 to 8 for geographical regions, 9 for the Army Postal Service). The first two digits combined designate the sub-region or postal circle (typically matching a state), while the third digit specifies the sorting district. The final three digits identify the specific delivery post office serving that locality.
India Post categorizes offices into Head Post Offices (HO), Sub Post Offices (SO), and Branch Post Offices (BO). Head Post Offices serve as regional administrative centers, Sub Post Offices handle urban and suburban mail and financial transactions, while Branch Post Offices extend postal coverage to rural villages.

A pincode, or postal index number, is the 6-digit code India Post uses to route mail. Every delivery post office in the country has one, and the same code is usually shared by several nearby offices.
The first digit is the postal region, the first two together identify the postal circle, the third narrows it to a sorting district, and the last three point to the specific delivery post office.
They do the same job. Pincode is the Indian term for a 6-digit postal code; ZIP code is the American term for a 5-digit one. They are not interchangeable between countries.

Yes, and most do. A pin code covers a delivery area, so neighbouring localities served by the same post office share one code.
