TAN Application - Confusion in Choosing Right AO Code

Check the CBDT website and use the Income tax department website and search for A.O.code using the option "Know Your AO" feauture

This suits best....

Dear, The thinker & Sri Rama Chary Rachakondaji , there isn't available A.O. Code of all the cities. I can tell you sir I am choosing my adjacent citi's A.O.code while applying for Tan No.& it's quite easily generated without any problem.

The AO code for TAN depends on your business address and entity type. On the NSDL Form 49B portal, you pick Area Code, Range Code, and AO Number from dropdowns for your state and city. For proprietors and individuals, use the AO range for your residential city, not the company or corporate AO range. If you have already submitted with the wrong code, you can file a TAN correction request (Form 49B with changes). For complete TDS and TAN setup for your business, Tax Garden handles this end to end under [TDS compliance services](https://taxgarden.in/services).
