Unfortunately, most declines are categorised by the card issuer as “generic” so it’s not always possible to know exactly why a payment was declined. First thing to do is to make sure that the postcode of your billing address matches the information that your card issuer/bank has on file for you. If you’d recently moved homes and haven’t updated your details, you may still have your previous postcode on file.
If all of the card information seems correct, it is best to contact your card issuer and ask for more information. For privacy and security, card issuers can only discuss the specifics of a declined payment with their cardholders – they cannot discuss this with us, or even with Stripe.
In addition, Stripe’s automated fraud prevention toolset, Radar, blocks any payments that we identify as being high-risk. Radar can help you most effectively combat fraud, with features such as rules that block payments if the CVC or doesn’t match the information on file with your customer’s card issuer.
