20 July 2025 For TAN registration related to Alwarpet, Chennai (Tamil Nadu), the AO Code you need is generally part of the Chennai jurisdiction under the Income Tax Department.

Here’s how you can find it:

Go to the official TAN AO code search page:
https://www.tin-nsdl.com/services/tan/tan-ao-code.html
Select Tamil Nadu as the state, and Chennai as the city.
In the list, Alwarpet falls under the Chennai South AO code, which is typically:
AO Code: CHNS (Chennai South)
Alternatively, you can also use the NSDL TAN AO search tool:

From the list, find Alwarpet or the closest locality, and note down the corresponding AO code.
