Info from ChatGPT below:

If your old Amazon Seller account was closed, whether you can open a new one depends on the reason for the closure:

- If Amazon closed your account (e.g., for policy violations, linked accounts, or fraud)

Amazon has strict policies against opening a new account if your previous one was closed for violations.

If you try to open a new account with the same personal details (name, address, bank account, IP address, etc.), Amazon may detect and suspend it.

You may be able to appeal the closure by contacting Amazon Seller Support.

- If you voluntarily closed your account

You can typically open a new account with the same details.

- However, if Amazon previously restricted your ability to sell, they may not allow you to register again.

Workarounds (If Amazon Denies a New Account)

Appeal the original account closure: If your previous account was closed due to a misunderstanding, you can submit an appeal.

Use completely new details: Some sellers attempt to register with new business details, a different address, bank account, and email. However, this is risky, as Amazon’s system is good at detecting linked accounts.

Register a new legal entity: If you set up a new business entity (like an LLC), you might have a better chance, but Amazon may still link it to your old account.
