You can personalize your Facebook URL (web address) by selecting a unique username. It will appear in the location bar of your browser after "http://www.facebook.com/" when you view your profile.

Starting at 12:01 a.m. (EDT) on Saturday, June 13, 2009, you will be able to select a username at http://www.facebook.com/username.

You can select a username that Facebook suggests or create your own. Select "Check availability" to check for available usernames. If the desired username is available, click "Confirm" in order to confirm your choice.

Users can only have one username for their personal profile. Similarly, Facebook Page administrators can only have one username for each Page.

You can change your username from the Settings tab of the Account Settings page. Scroll down to "Username" and click "change." Then follow the on-screen directions. Keep in mind you will only be able to change your username once.

Not at this time. Usernames can only contain alphanumeric characters (A-Z, 0-9) or a period ("."). We're looking at how we may potentially support non-romanized characters in the future.

Once you have claimed a username by clicking the "Confirm" button after checking for a username's availability, it is not possible to transfer your username to a different account on Facebook. Additionally, when an account is removed from the site, its username will not be made available. Facebook does this for security reasons.

You should make sure it is something you like and that it’s appropriate for friends, family, co-workers, and anyone else who might use it to find you.

You may not be able to claim a username for several reasons. Usernames can only contain alphanumeric characters (A-Z, 0-9) or a period ("."), for example -- john.smith55. It is important to note that a period (".") does not count as a part of a username; therefore, names like johnsmith55, john.smith55, john.smith.55, etc. all constitute the same username. Usernames also must be at least 5 characters long. Usernames are not case sensitive. Facebook also prevents certain words from being included in usernames. It is not possible to copy a username that someone else has already claimed.

If Facebook has indicated that your username cannot be claimed, you will need to select a different one. You will see a green checkmark indicating that a potential username is available before you actually claim it.

No. A period (".") does not count as a part of a username; therefore, names like johnsmith55, john.smith55, john.smith.55, etc. all constitute the same username.

No. Your username will adhere to the privacy settings you created for your profile.

Usernames are available only for Facebook profiles and Pages. It is not possible to claim a username for a group or event created with these Facebook applications.

Facebook reserves the right to remove and/or reclaim any username at any time for any reason.

Yes. People can set one and only one username for their personal profile. Similarly, Facebook Page administrators can only have one and only one username for each Page they administer.

People have to click on the "Confirm" button to finalize their selection. After that time, it cannot be changed.

To prevent username squatting and other activities that would limit options for other users, we have a strict no transferability policy.

After 11:59 p.m. (EDT) on Sunday, June 28, 2009. Users will be required to have a verified Facebook account, which may require mobile phone authentication.

Immediately. After the username has been confirmed, people will be given the option to publish the new username into the stream to inform friends, family and co-workers.

At this time, usernames are not accessible through the Platform API.

We think there are many options for users to choose a username that represents their identity. But we also wanted to help our users avoid potential disputes concerning usernames that may be protected by intellectual property rights. In order to do that, we have encouraged rights owners to contact us if they want to reserve/protect certain names.

We've taken steps to limit this behavior. Only those who created accounts before username availability was publicly announced at 3 p.m. on June 9, 2009 will be eligible during the first wave, which lasts until 11:59 p.m. On Sunday, June 28, 2009. After 11:59 p.m. Users will be required to have a verified Facebook account, which may require mobile phone authentication. This decision was made to prevent people from creating new accounts just to take advantage of reserving a username. We've also reserved certain names that have been brought to our attention in an effort to help third parties protect their intellectual property and other rights. We also have a strict no transferability policy. If we determine that usage of a username is for squatting, that username will be reclaimed by Facebook.

A Facebook username should have a clear connection to one's identity. Impersonating anyone or anything is prohibited by Facebook’s policies. To select a new username, please visit www.facebook.com/username

Facebook encourages all users to utilize the "Report" links when they find abusive content. You can report an abusive username by selecting the "Report this Person" link located on the bottom left side of that person's profile. This takes you to a form where you can specify the type of abuse and make a detailed report. Facebook investigates these reports and makes a determination as to whether or not the content should remain on the site. All abuse reports on Facebook are confidential.

If your account was compromised and a username was selected without your consent, please report the issue here.

Please make sure that the email associated with your account is secure. If you're having trouble logging in with your normal email and password, try resetting your password using the link on the login page. An email will be sent to you with steps for completing the process. If the email on your account has been changed, or if you are unable to access your profile, please send include information about the account in your report so we can look into it further and hopefully restore access.
