A User ID is the unique nickname you use to identify yourself on eBay.

When you register at eBay, choose a User ID that you like and that you'll remember. For example:

• You might use words identifying your favorite collecting area, your business, or occupation.

• You could refer to your hometown and call yourself camberwell_beauty.

• Or refer to your own sense of style and choose something like Del_Boy303.

Remember that User IDs:

• May contain letters (a-z), numbers (0-9), and/or many symbols

• Must be at least two characters long

• Can't contain spaces

• Can't be obscene, profane, or hateful

• Can?t be or resemble an email address or website

Things you can't include:

• The @, &, <, or > symbol

• URLs (for example xyz.com)

• Consecutive underscores "__"

• An underscore "_", dash "-", or period "." at the beginning of a User ID

• Spaces or tabs

• The word "eBay"—only eBay employees may use "eBay" in their User IDs

• The letter "e" followed by numbers

Tip: If you forget your User ID, you can have it sent to your registered email address.

Note: You can only change your User ID once in a 30-day period. This is to prevent confusion for the rest of us. Keep in mind that your User ID is a valuable asset, like your feedback rating. Trading partners will come to recognize you by your User ID, so it's a good idea to choose one you'll want to use for the long term.
