e-TDS :- Requirement of Authentication Code at tdscpc.gov.in
Should I enter Authentication Code if I am trying to clear validation details for the first time during a day?
No. While trying to clear validation details for first time, you will not have the Authentication Code, hence you are not required to enter this value. You can proceed by entering other details for validation on this screen (i.e., Token Number, CIN / BIN Details and PAN-Amount). On completion of validation, Authentication Code will be generated and displayed when you proceed to next page.
Is it mandatory to enter Authentication Code?
No. If Authentication Code has been generated for the statement for which you are filling up validation details, you can enter it in the field provided for the same. It will facilitate users to avoid filling up validation details repeatedly in case user logs in again at different time of the day. If it has not been generated or if you have not saved it, you can proceed by entering other details on this screen (i.e., Token Number, CIN / BIN Details and PAN-Amount).
