Changing your username
When you register with eBay, you choose a username to identify yourself when you sign in, and when you bid, buy, or sell.
How to change your username
Go to the change username page and enter the new username you’d like to use. Get tips on what's allowed and not allowed in a username.
For future reference, to change your username or other account information:
Click My eBay at the top of most eBay pages.
Click the “Personal Information” link on the left side of the page.
Click the “Edit” link to the right of the information you want to change.
What happens when you change your username
Your new username automatically replaces your old username wherever it appears on eBay. All your member and account information, including your Feedback score, will be transferred to your new username.
The "Changed username" icon will appear next to your username for 30 days.
Your old username can't be used by anyone else at eBay for 30 days.
You can change your username only once in 30 days. This helps prevent confusion for other members.
Along with your Feedback profile, your username represents your reputation on eBay. Over time, you can build your reputation into a valuable business asset, so it's a good idea to choose a username you'll want to use long-term.
Tip: If you forget your username, try using your registered email address.
