I have an existing Seller account but stopped. Should I create a new account?

No! DO NOT CREATE A NEW ACCOUNT.

No! DO NOT CREATE A NEW ACCOUNT. The reason for this, is that based on Section 3 of the Amazon Business Solutions Agreement, you are only allowed to have ONE Amazon account. Additional Amazon accounts may result in getting your account(s) deactivated.

Please contact Amazon and try to get your old Amazon Seller Central Account reactivated.
