User IDs


A User ID is the unique name that members use to identify themselves on eBay. At registration, members should choose a User ID that they like and will remember. User IDs may not be profane, obscene, or violate any eBay guidelines. Furthermore, User IDs may not be an email address or Web address (URL) or represent an email address or Web address. For more specific information and examples of what is and is not permissible, please review the Examples and Additional Information sections below.

Violations of this policy may result in a range of actions, including:

  • Listing cancellation

  • Limits on account privileges

  • Account suspension

  • Forfeit of eBay fees on cancelled listings

Report a User ID that may be inappropriate.

  • You might use words identifying you and your favourite collecting area; for example, JoeTheBookCollector

  • You could refer to your business; for example, BertsBestBikes

  • You could refer to your location; for example, jurong_jimmy

  • You can refer to your own sense of style or your personality; for example, happyharry

There are some guidelines and restrictions as to what User IDs may contain or represent. For example, User IDs:

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

  • Must be at least two characters long.

  • Can be an element of an email address or Web address (URL) that, when viewed outside the context of the email address or Web address, identifies you or your brand.

What you can't include in your User ID:

  • The @, &, , (, ), <, or > character.

  • Spaces or tabs.

    Tip: You can instead use a hyphen to represent a space.

  • Elements that imply an email address or Web address (for example,, including but not limited to .com, .net, .org, .edu or any variation of such (for example, _com or -com). Your User ID can however contain an element of an email address or Web address that, when viewed outside the context of the email address or Web address, identifies you or your brand (for example, xyz).

  • Phone numbers (numeric or alphanumeric).

  • Consecutive underscores __.

  • An underscore _, hyphen -, or period . at the beginning of a User ID (for example, -pezcollector).

  • The word eBay (only eBay employees can use the word eBay in their User IDs).

  • The letter e followed by numbers.

  • Obscene or profane words that violate eBay's guidelines. See eBay’s rules on profanity.

  • The same User ID as another seller or similar to an eBay Store name.

  • A term that is similar to, or might be confused with, a third-party's trademark or brand (for example, CocaColaSeller).

Note: If you received the message You have entered a User ID that is not allowed, you may have included a character that is not allowed in a User ID.

You can only change your User ID once in a 30-day period. This is to prevent confusion for other eBay members. Keep in mind that your User ID is a valuable asset on eBay, like your Feedback Score. Buyers and sellers will recognise you by your User ID, so it's a good idea to choose one that you'll want to use for the long term.

Information for members whose current User ID is or represents an email address or Web address (URL): eBay is constantly working to provide a safer and easier trading experience for our members. As a result, we have decided to no longer allow User IDs that are an email address, a Web address (URL), or a lookalike for either. If you have a current eBay User ID registered after November 2001 (when eBay’s User ID policy was instituted) that is also an email address, a Web address, or is a look alike for either, you must change your User ID to comply with this policy. eBay may take a range of actions with regard to User IDs not in compliance, including suspension of the associated account.

If you have not used eBay in over a year, and your User ID was also your email address, you may have received an email informing you that a new temporary User ID was created for you. Use that new User ID whenever you sign in to eBay. If you like, you can change your User ID to another one that you prefer.

eBay Store names: Store names are another form of identification on eBay. eBay Store names follow the same guidelines and restrictions as eBay User IDs with two exceptions which allow greater flexibility:

  • Spaces (example: Happy Harry)

  • Symbols such as & (example: Bert’s Best Bikes & Trikes)

User IDs are a key building block of member identity and the eBay Community. This policy helps members understand how to choose good User IDs.
