You can create an anonymous seller account with eBay in order to prevent sharing your identity with people who view your eBay profile. Although eBay requires you to place a credit or debit file in order to confirm your identity for secure transactions, it doesn't reveal this information to people who bid on your auctions. Provide an anonymous email address, a made-up location and a username that conceals your identity to use eBay as anonymously as possible.
Sign in to your eBay buyer's account if you have one. Alternatively, register for your first eBay account by clicking "Register." Provide eBay with your name and address, a working email address and your desired username and password. Use an alias, a past address and anonymous email address if you choose -- proof of identity isn't required to create or use the eBay account, only to authorize the initial creation of the seller's account.
Go to "My eBay" and choose "Create Seller's Account." Input a credit card or debit card number -- or, alternatively, a checking account number -- the name and billing details on the account and click "Add Account." EBay takes seller's fees from this account, but doesn't reveal the name on it to anyone with whom you transact. Optionally, you can input PayPal account information, although buyers who transact with you can see your real name if you do this.
Click the boxes next to any of the payment methods you accept -- Visa, Discover or PayPal, for example. Click the "Finish" button to begin resuming your seller's account, which is anonymous to all users with whom you interact unless you choose to reveal your identity or transact via PayPal.
