The best way to check is through the SBI Card app. Find your cashback summary on the first page itself. It shows the cashback you earned after the last statement, as well as the cashback earned this year. After the transactions are settled, this number may update (if it is valid for cashback).
Another way to check is to call SBI Cards Customer Care number and ask for the MCC after the transaction has been settled (within 24-72 hours). Then, research on TF or Reddit to check whether this MCC is valid for cashback.
As far as I know, this applies to all the banks (pls reply if I am wrong 🙏🏾). So if the cashback is not visible for a particular bank, CALL and VERIFY.
