What address should I use instead of my home address as an Amazon seller?

The best way to keep your personal information (not using your home address) and out of the public is to obtain a PO Box or commercial business address.

The disadvantage of using a PO Box is that you might run into issues verifying that it is a physical business address. See how others have had success with it - New Amazon Selling Rules/Documentation and a PO Box - Seller Verification - Amazon Seller Forums

Another option is a virtual mailbox, which gives you a commercial street address attached to a commercial business address - you can learn How to Keep Your Amazon Seller Address Private | VirtualPostMail Blog
