Certain cards maybe rejected by banks due security measures, please contact you bank if you are unable to add your card and let them know you are trying to register to sell on Amazon.

For issues and validation of credit cards, please review this resource and ensure the requirements below are met.

Credit Card Requirements

* Is the credit card valid?

* Is there a minimum charge amount?

* Are you using a pre-paid card? (Note: Use of a pre-paid card is not accepted for a selling account.)

* Does the bank have a record of the charge attempt?

* Are there bank limits or policies that prevent the charge attempt from being authorized?

* Is there any incorrect credit card information entered? (Note: All the credit card information entered such as number, name, address, ZIP code, or expiration date must be an exact match with your card details.)

* Is this chargeable in the currency of the Amazon marketplace where you registered your seller account?

Cheers,

Connor
