Not really. Also, to be clear, TC40 chargebacks donât exist, and TC40 data doesnât really have an effect on chargebacks one way or the other. TC40s are sometimes misinterpreted as a way to proactively prevent chargebacks. But, as we outlined above, theyâre cumbersome and usually inaccessible, and are not a reliable chargeback indicator. Also, while TC40 data claims are usually released within a few days after a fraud report, they donât stop chargebacks from being filed.
