Chennai Pin Code List: Complete Area-Wise Guide

Chennai is a vast metropolitan city stretching from the historic core around Fort St. George, George Town and Mylapore to major residential and commercial districts such as T. Nagar, Anna Nagar, Adyar and Velachery, and further into large suburban corridors around Tambaram, Ambattur and Old Mahabalipuram Road. Its postal network reflects this scale, with a long series of six-digit PIN codes beginning with 600.

Chennai GPO uses 600001, Anna Road uses 600002, Mylapore uses 600004, Egmore uses 600008, T. Nagar uses 600017, Adyar uses 600020, Nungambakkam uses 600034, Anna Nagar uses 600040, Velachery uses 600042 and Tambaram uses 600045. The IT corridor has additional codes, including 600097 for Thoraipakkam and 600119 for Sholinganallur.

Because many localities merge into one another and several suburban names are used broadly in real-estate and delivery addresses, the precise PIN code is important. The area-wise guide below covers major central, north, south and suburban Chennai postal zones for day-to-day and official use.

Central Chennai PIN Codes

Central Chennai contains the city’s historic, government, business and cultural districts.

North and North-Central Chennai PIN Codes

North Chennai includes old residential neighbourhoods, port-side areas and important transport and industrial zones.

South Chennai and OMR PIN Codes

South Chennai includes major residential, educational, business and IT destinations.

Tambaram, Ambattur and Suburban Chennai PIN Codes

The wider Chennai metropolitan area includes large suburban municipalities and industrial-residential corridors.

Why Do Nearby Chennai Areas Have Different PIN Codes?

Chennai’s metropolitan boundaries are much larger than a single postal delivery area. PIN codes follow post offices and sorting routes, so two adjoining neighbourhoods can use different codes. This is especially important along OMR, GST Road and the Tambaram-Ambattur suburban belts.

Understanding a Chennai PIN Code

Chennai PIN codes generally begin with 600. The six digits narrow the address from the postal region to the specific delivery office. The city name alone is not enough for precise routing, particularly for large apartment, IT and industrial areas.

How to Confirm the Correct Chennai PIN

For an exact home, apartment, office or institutional address, compare the PIN with a recent utility bill, bank correspondence, registered document or a previously delivered parcel. India Post’s post-office locator can also be used to verify the delivery office. This is particularly useful when a locality lies close to the boundary of two postal zones or when a project uses a broader marketing locality name.
