Hello @Seller_ll4yeab6RRGDD,

I'm Angie, part of the UK forum community. It's a pleasure to greet you.

This could be for different reason, as per the help page Seller credit or debit card FAQ these are the credit/debit card requirements:

• The number that you entered must match the number on your credit or debit card.
• The billing address that you entered must match the billing address on your credit or debit card statement.
• The CVV code that you entered must match the code on your credit or debit card.
• The card expiry date must be at least six months from when you add the card.
• The cardholder’s name that you entered must match the cardholder’s name on your credit or debit card (in the Latin-script alphabet).
• The card must not be a prepaid, virtual or gift card.
• The card must be chargeable in the currency of the Amazon store or stores for which the card is being provided.
• The card must have adequate credit limit to pay for the charge.
• If you were asked to enter a unique security code by your financial institution, the code that you entered must match the code sent to the cardholder via SMS, email, or token.
• Multi-factor authentication must be completed. For existing cards, please re-add the card in Seller Central and complete the authentication challenge.

If your card meets all the requirements above, but is still listed as invalid, we recommend that you try a different card or contact your financial institution for assistance.

Regards,

Angie 🪴
