Amazon officially stipulates that a person or company can only have one Amazon account. If Amazon uses technical means to monitor and check various data and match related factors, if it is found that a seller has more than two Amazon accounts, these accounts will be determined to be related accounts. After summarizing, Amazon mainly tracks sellers from the following aspects:

1. User's IP address

2. Amazon user login name

3. Email address

4. Amazon login password

5. Browser and browser plug-in

6. Computer operating system

7. Cookies stored on your computer, including text and Flash cookies. Amazon account association usually leads to three results:

1. If several accounts on the same site are associated, if the products sold by the accounts overlap, they will generally be required to forcibly remove all listings of the new account; 2. If several accounts on the same site are associated, if the products sold by each account are different and the account performs well, then all of them may continue to survive; 3. For any site, if one of the associated accounts has been closed, then the other accounts will definitely be closed, and the closing time is uncertain
