Successive seller accounts blocked after EIN error and duplicate info, need advice

Hey all,

We’re stuck on the first hurdle and not sure what the next step is. We are new to Amazon and are setting up Amazon Seller accounts.

• First account was blocked because we mistakenly entered the EIN and business registration number incorrectly.
• Amazon Support told us we could not fix it and advised us to open a new account.
• Second account was set up correctly, but it was also blocked because Amazon flagged it as a duplicate.

Both accounts used the same business name, address, domestic address, and phone number. The only difference was the email address, which still used the same business domain suffix.

Now both accounts are blocked. We just want to move forward with one account, either by fixing the first or closing it so the second can proceed.

Has anyone had this happen before? How did you get Amazon to resolve it? What is the best move here?

Thanks in advance.
