Amazon links rejected and new seller accounts using multiple types of evidence that identify connections between them, which can lead to suspension or blocking of the new account if it is deemed linked to a prior rejected account. Key evidence Amazon uses includes:
Shared Financial Information: The same bank account numbers, credit cards, or tax identification numbers linking multiple accounts is a major red flag and often causes accounts to be flagged as linked.
Login and Contact Details: Reuse of the same email addresses, phone numbers, and IP addresses used to access multiple accounts signals linkage.
Device and Network Data: Amazon tracks device fingerprints, IP addresses, browser and software versions, and even login patterns—all used to detect if accounts are operated by the same person or entity.
Operational Overlaps: Shared resources such as customer service contacts, warehouse locations, inventory management systems, or even linked business addresses and phone numbers.
Previous Account History: If an account has been suspended or rejected for policy violations, Amazon actively prevents the same person or entity from re-registering with overlapping information to circumvent enforcement.
Cookies and Browser Storage: Information saved on devices from prior logins can also betray attempts to open new accounts on the same devices.
Amazon’s detection tools are complex, combining automated algorithms and manual review to enforce strict rules against multiple unauthorized accounts. Sellers linked through any of these factors without Amazon’s explicit permission risk suspension, deactivation, or permanent bans.
To avoid this, sellers must provide wholly distinct and verifiable information or seek Amazon’s prior approval for multiple accounts.
