stripe sepa iban invalid checkout europe
IBAN validation failures look like EU checkout ‘broken.’ Fix validation messaging, then confirm SEPA fees don’t get blamed on the form error.
The actual problem
IBAN validation errors kill EU SEPA checkouts that would have succeeded with clearer input UX.
Do this
- Log SEPA failure codes for 14 days; separate invalid IBAN vs bank declines.
- Add IBAN formatting/help text before submit.
- Offer card as secondary method on the same checkout.
- Compare EU CVR before/after UX fixes.
