Amazon will not help you cancel your business license. When buying or selling an Amazon store, the platform where you conduct the transaction will not help you cancel the store's business license. To apply to the registration authority to cancel the business license, in addition to submitting the relevant materials required for the cancellation of the business license to the registration authority, the Amazon store operator must also conduct identity authentication and upload a portrait video. The trading platform cannot record and upload the operator's portrait video. Therefore, Amazon will not help you cancel the business license.
