Amazon sent an email to sellers warning them it's against its policy to use multiple selling accounts, and warning them that if "certain circumstances" warranted them doing so, to make sure they listed the accounts in their Seller Central account explaining why.
Some sellers thought it was a spoof email while some worried it specifically directed at them even though they weren't violating the policy - but it appears it was sent to many sellers:
As we continue to ensure our marketplace is safe and trustworthy for both buyers and sellers, we would like your help. Amazon prohibits the use or maintenance of more than one seller account.
We understand that in certain circumstances you may need to use multiple accounts or associate one or more accounts to your seller account.
In an effort to better understand the business requirements that you may have for multiple or related accounts, we request you to list these accounts in Seller Central along with the reason for relating them to your seller account.
Simply click or copy and paste the link below into your web browser to access your account within Seller Central and provide any and all email addresses and reasons for their use - it's that easy.
For more information, see the following Help page.
The policy is a big no-no - and if you are found operating multiple selling accounts without permission, you could be permanently suspended. According to the policy
: "Operating and maintaining multiple Seller Central accounts is prohibited. If you have a legitimate business need for a second account, you can apply for an exception to this policy."
It's not clear why Amazon sent the email to sellers in compliance, but it certainly caused some fear, uncertainty, and doubt among recipients of the letter.
