In order to focus on the buyer’s shopping experience and prevent sellers from repeatedly selling the same products, Amazon’s rules tend to allow the same product to appear only once on the platform. Follow-selling is also based on this concept. In order to ensure fair competition among sellers and provide customers with the best quality products, Amazon’s pages do not emphasize the concept of stores, but focus on products, that is, “focusing on products rather than stores”. There may be multiple sellers on the same product details page.

Amazon officially stipulates that a person or company can only have one Amazon account. Amazon uses technical means to monitor and verify various data and match related factors. If it is found that a seller has two or more Amazon accounts on the same site, these accounts will be judged as related accounts.

1) Consequences of account association:

① If several accounts on the same site are associated, and the products sold by the accounts overlap, all listings of the new account will generally be forced to be removed;

② If several accounts on the same site are associated, if the products sold by each account are different and the accounts perform well, then all of them may continue to survive;

③ On any site, if one of the associated accounts has been closed, then the other accounts may also be closed, and the closing time is uncertain. If the store is closed due to account association, the seller will not be able to enter the backend, which means that the seller cannot file a complaint.

2) Factors for determining account association:

① Computer: mainly refers to hard disk information.

② Network cable: mainly refers to the external network IP address. However, since most domestic IPs are floating IPs, it is inevitable that multiple accounts have the same IP, so the IP address is only one factor in determining association, not the only factor.

③ Network card MAC address: Some sellers, based on cost considerations, format the computer and reinstall the system after an account is closed, and then log in to a new account. If the computer network card is integrated, and the network card is not disabled or replaced with a new one, it is also easy to cause account association.

④ Router.

⑤ Browser fingerprint: such as plug-ins, Cookies, system fonts, operating system version, typing method, typing speed, etc.

⑥ Email: pictures or Flash.

⑦ Account information: registrant name, credit card holder name, payment account information, email address, address information, phone number, password, etc., should be as different as possible and have no rules to follow.

3) How to prevent account association. In the process of registering multiple accounts, try to use new emails, new computers, new systems, new routers, new network cables, new phone numbers, new credit cards, new payment accounts and new products, and try to avoid being captured by the Amazon system in a physical isolation manner. The determination of account association is based on a comprehensive determination of multiple factors, and a single factor may not directly lead to account association. The high similarity of multiple factors will inevitably increase the risk of being determined as an associated account.

It should be noted that there is no reminder for Amazon account association, no email notification, no customer service contact, no background warning, and whether to associate or not is up to the seller to decide. In addition, account association is irreversible. Once the system determines that the account is associated, there is no chance to exit the association list.

In addition, there will be associations between different sites, but if one of the sites has a problem, it is rare for the other account to have problems as well. Because Amazon supports sellers to open stores at various sites and sell products to various regions. At the same time, associations are not only for seller accounts and seller accounts, but also for seller accounts and buyer accounts. Therefore, everyone needs to avoid the situation where the seller account is restricted due to buyer account problems.
