PIN Code 631605 – Nathanallur, Tamil Nadu

PIN Code 631605 for Nathanallur, Tamil Nadu is part of the India postal code system, which uses a numeric code of 6 digits (e.g. 110001). Addresses here are organised as State / Union Territory → District → Subdistrict / Taluk / Tehsil → Locality / Village / Town.

Administratively it is recorded in Tamil Nadu within India. Postal codes are assigned by delivery route rather than by administrative boundary, so a single code can cover more than one locality and a locality can fall under several codes.

No building-level records are held for this code in the imported dataset, so only the code and its location details are shown. The absence of records does not mean the pin code is unused.

Couriers, e-commerce checkout forms and address autocomplete tools all rely on the pin code to route mail and to check that a stated address matches the code. Because a pin code identifies a delivery area rather than a single building, two addresses that share the same code can still be some distance apart.

Always write India PIN Code in full when completing a form, including any leading zero. Enter a 6-digit Indian PIN Code. Data source: a third-party open dataset. This is a reference snapshot, not a live government feed, so confirm the code with the sender, carrier or postal authority before relying on it.
