Hello there @Seller_jcuf358dPKLg0

My name is CR and want to provide you with some information below.

This link will take you to a page with a lot of great information on updating/changing your bank account. A few things from this page to note:

Important: Whenever you add or change your bank account information, a three-day security hold goes into effect. Fund transfers cannot be initiated until the hold expires, including those from any settlement cycles that close during the hold period. We recommend that you do not update your bank account within three days of your next regularly scheduled disbursement to avoid any delays in payments. Only the primary account owner can make changes related to payment information.

Note: Bank account verification may take from 48 to 72 hours to complete. We'll notify you via email when your bank account has been verified or to inform you of any additional steps that are required. If you choose to use a different bank account for verification, or if you add a new bank account for verification, you must assign the verified bank account to the Amazon.com store from the Assign Deposit Method or Replace Deposit Method pages.

Lastly, this page is helpful to review for reasons why your bank account may be rejected.
