Choosing a user ID

Creating a user ID

A user ID is the unique name you use to identify yourself on eBay and is seen by other eBay users. Your user ID is displayed when you buy or sell on eBay or communicate with other members. Other members can't see your real name or other personal information.

When you register on eBay, we'll automatically assign you a user ID. If you'd like to create your own user ID, go to My eBay, click the Account tab and go to Personal Information. After that, you can change your user ID only once in a 30-day period.

Rules for user IDs

Valid user IDs must be at least 6 characters in length. Your user ID can only include letters, numbers, periods, asterisks, underscores or dashes. As you type in a possible user ID, we'll provide suggestions of what's available.

You can use either your email address or your user ID to sign in to eBay. If you choose your own user ID, pick one that you like and will remember. Since other members will see it, we recommend you don't include your real name or other personal information in your user ID.

User IDs can't contain:
  • Any characters except letters, numbers, spaces/periods, * asterisks, _ underscores, or - dashes.

  • Elements that imply an email address or web address including but not limited to .com, .net, .org, .edu, or any variation (for example, _com or -com). However, your user ID can contain an element of an email address or web address that identifies you or your brand. For example, if your web address is you can use xyz as an element of your user ID.

  • Consecutive underscores _ _ .

  • An _ underscore, - hyphen, or space/period at the beginning or end of a user ID (for example, -cardcollector).

  • 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 our rules on profanity.

  • The same user ID as another member.

  • A user ID that is similar to the name of an eBay Store.

  • A term that could be confused with someone else's trademark or brand (for example, CocaColaSeller).

Creating eBay Store names

Store names are another form of identification on eBay. You have more flexibility in creating eBay Store names. For example, spaces and symbols (such as &) are allowed in Store names.

The name you choose when you set up your Store determines your Store's URL (website address). As part of creating your URL, we change all letters in your Store name to lowercase, remove any special characters (apostrophes, spaces, &, $, etc.), and add hyphens between all words. For example, if your Store's name is "Fine Jewellery," your Store's URL is

Choose a name that immediately lets buyers know what you are selling. For example, a straightforward name such as "Ben's Computers" will be more helpful to buyers than a less descriptive name. A straightforward Store name can also help search engines find your Store when buyers are looking for your items.

Rules for Store names

Your Store name must follow these guidelines:
  • It must start and end with a letter or number

  • It can't start with four or more consecutive letter As

  • It can't start with an "e" or "E" followed by more than a single number

  • It shouldn't contain the following characters: <, >, or @

  • It can't be the user ID of another member on eBay, or be misleadingly similar to the user ID of another eBay member

  • It can't contain "www" anywhere in the name

  • It can't contain two or more consecutive spaces or non-alphanumeric characters

  • It can't end with a top-level domain abbreviation used on the web such as .com, .net or .org

  • It can't be a name that is identical or misleadingly similar to another company's name protected by trademark law. Also, you may not use a name that contains the word eBay or PayPal, or which is misleadingly similar to those names. Learn more about Trademarked items and domain name basics.

Your Store name can be your eBay user ID, as long as it meets these guidelines.
