AIN, PAO Code, DDO Code are the details like CIN which are applicable for Govt Deductors like Govt Schools etc. These can be obtained when you verify the detail in BIN.

Generally, these are asked when you ADD Challan to your correction statement. As of now, you cannot add any challan manually but you need to update this through online correction mode. During Online correction, select correction type "Add Challan to Statement".-> Add Challan-> there will be window showing detail of available / unconsumed challans in CIN / BIN detail. Select the relevant challan and then Submit for processing.

In case, your client is not Govt deductor and still these information is asked by utility, check the TYPE OF DEDUCTOR selected by you in correction return. When you change it to other categories, instead of above detail, it will ask for CIN detail like BSR Code, Challan Date and Challan number.
