Recovery guidance
What to do when Stripe returns incorrect_cvc
What it means for the customer
The card may be usable, but the verification details need correction before the payment can succeed.
First recovery move
Send a short email asking the customer to re-enter or update their payment details through a secure billing link.
Retry timing
Retry after corrected details are submitted. Retrying the same incorrect card data is unlikely to help.
Email angle
Keep it practical: the card verification details did not match, and the customer can fix it by updating payment details.
What to avoid
Avoid asking the customer to email card details or CVC. Keep all sensitive information inside Stripe-hosted flows.
