Kolkata Pin Code List: Complete Area-Wise Guide

Kolkata has one of India’s most intricate urban postal networks because the city combines a dense historic core with large residential districts, institutional zones, industrial pockets and newer eastern developments. Kolkata GPO uses 700001, but a short journey across the city can move an address into another postal code: Park Street uses 700016, Ballygunge 700019, Alipore 700027, Jadavpur 700032, Behala 700034 and New Alipore 700053. Salt Lake and New Town add further codes on the eastern side of the metropolitan area.

This variety makes a correct PIN especially important. Kolkata addresses often rely on old road names, para or neighbourhood names, municipal wards, landmark-based descriptions and post-office names that do not always match one another. A correct six-digit PIN helps postal and courier systems resolve those differences, while a wrong code can direct the consignment to another delivery office.

The area-wise guide below covers major central, north, south and east Kolkata postal zones. It is intended for residents, businesses, students and visitors who need a reliable starting point for address forms, courier labels, online deliveries and documentation. For building-level accuracy, the code should still be checked against the serving post office.

Why Kolkata PIN Codes Change So Quickly Across Neighbourhoods

The city contains many long-established post offices within a relatively compact area. Historic neighbourhoods developed separate delivery jurisdictions, and later growth toward Salt Lake and New Town created additional postal zones.

Kolkata vs Greater Kolkata Addresses

People often use ‘Kolkata’ for places across the wider metropolitan area. The postal address may officially show another locality, municipality or post office. The PIN and serving post office are more precise than the broad metropolitan label.

Old Street Names and Postal Accuracy

Kolkata is known for roads that have both historic and renamed forms. Couriers can usually handle familiar alternatives, but the PIN and locality should remain correct. For government or bank records, follow the wording used on accepted address proof.

FAQs

Q. Why can neighbouring Kolkata paras have different PIN codes?

Many Kolkata post offices were established around distinct neighbourhoods and delivery routes. Dense urban development means those postal boundaries can sit very close to one another.

Q. Should I use the locality name or the post-office name in a Kolkata address?

Use the familiar locality for clarity, but make sure the PIN corresponds to the serving post office. For official documents, follow the address format on your accepted proof.

Q. Can a Salt Lake or New Town address be written simply as Kolkata?

Many people use Kolkata as the broad city label, but the exact sector, action area, post office and PIN are more important for routing. Preserve the locality details used by the property or institution.

Q. How can I avoid courier problems when a Kolkata road has an old and new name?

Include the building number, locality and correct PIN. If space permits, adding the commonly known landmark or alternate road name can help the final-mile courier without changing the official postal code.
