TAN Application - Confusion in Choosing Right AO Code

I have been trying to find correct AO Code for individual who is living in Bangalore, with annual TDS/TCS > 10 Lakh and name from R to Z.

When I select other cities like Mumbai in TAN application, it is much easier to find AO code, however for Bangalore, I do not really see any option that fits my criteria. For half of wards, the remark section is empty. For section where remarks are present, it does not fit the criteria.

How does one manage through such scenario?
