Amazon account association means connecting different accounts, which can facilitate users to share information between multiple accounts, such as delivery addresses, payment methods, etc.

The solution is to log in to the Amazon account, click "Link other accounts" on the "Accounts and Lists" page, enter the account information to be associated for verification, and the association can be completed. Note that once the association is successful, all associated accounts will share data. It is recommended to only associate your own account or an account you trust.
