Seller accounts generally are not transferable. Seller accounts provide access to the tools and resources that sellers use to list their products and manage their orders. Seller accounts also include account activity history and buyer feedback. Every seller on Amazon must have a seller account and an agreement with Amazon that establishes the terms under which the seller lists and sells their products.
If the ownership of a business changes for any reason, the new owner needs to establish a new seller account.
If the ownership of a business isn't changing, but the individuals responsible for managing the seller account have changed, you can add users to the account. For more information, see Set User Permissions.
