What Is a PIN Code?

PIN stands for Postal Index Number. It is a six-digit code introduced by India Post on 15 August 1972 to simplify mail sorting and delivery across India. Each PIN code helps identify a postal region, sorting district and delivery post office.

A correct PIN code helps postal staff route letters, documents and parcels to the appropriate delivery office. It is important to verify the code against the recipient's full address because nearby localities can have different PIN codes, while multiple post offices may share the same code.

How Does India's Six-Digit PIN Code System Work?

Each digit in an Indian PIN code has a specific role in postal routing. The digits work together to narrow the destination from a broad postal region to an individual delivery post office.

• First digit – Postal zone: Identifies one of India's eight geographical postal regions or the ninth zone reserved for the Army Postal Service.
• Second digit – Sub-zone: Narrows the location to a sub-region within the postal zone.
• Third digit – Sorting district: Together, the first three digits identify the sorting district.
• Fourth digit – Sorting route: Indicates the route on which the delivery office is located within the sorting district.
• Last two digits – Delivery post office: Identify the individual post office.

For example, PIN code 110001 belongs to the New Delhi area. Its digits help route mail through the relevant postal region and sorting network to the destination post office.

Postal Zones in India

India's PIN code system is organised into eight geographical postal zones and one functional zone for the Army Postal Service. The first digit indicates the zone, while the remaining digits narrow down the destination.

The table provides a broad overview of postal zones. For a specific locality or post office, use the detailed PIN code directory or verify the code through the official India Post locator.

Why Is a PIN Code Important?

A PIN code helps identify the postal delivery area associated with an address. It is commonly required for:

• Sending letters, documents and parcels through postal and courier services.
• Entering a residential or business address during online purchases.
• Completing bank forms and other financial applications that request a postal address.
• Checking the delivery coverage of a service or shipment.
• Distinguishing between localities with similar names.

A PIN code supports address identification but does not replace the full address. Always provide the correct house or building number, street, locality, city and state along with the PIN code.
