Accounts Officer Identification Number (AIN) is a seven digit unique identification number issued by the Directorate of Income Tax (Systems) Delhi to each Accounts Officer (AO). It is mandatory for an AO to have an AIN for submitting the e-TBAF. In the Government Accounting System each DDO (Drawing & Disbursement Officer) is associated with a specific Accounts Officer (AO) who processes the bills prepared by the DDO inTDS/TCS Book Adjustment Form (e-TBAF). 

Kindly check as to which e-tds return form you are filling as you are not required to have a AIN number.
