A username is a unique string of characters which can be used to identify a user on Roblox. Players can select any available username of their choice upon creating an account, however the cost to change the username becomes 1,000 Robux after the account has been created.


During the early stages of Roblox, usernames could have spaces in them, such as John Doe and Jane Doe, this feature was later removed in December 2006 due to users impersonating other users by using spaces.

In February 2016, underscores were added back into the allowed list of characters in usernames (the first time since they were initially removed back in 2006).

In 2018, users were prevented from having usernames made up of only numbers. This was to prevent users creating usernames of phone numbers and because Roblox was adding a login by phone number feature. Currently, Roblox usernames can consist of 3-20 characters using letters, numbers and a single underscore ( _ ) which must not be the first or last character of the username.

Changing Usernames

Users with [ Content Deleted ] in their names, most accounts have been closed after a hacking rumor was created by YouTubers in June 2017.

Originally, users were only allowed to change their names due to either privacy concerns (such as the username being a player's full name) or per request by the moderation team due to the name violating the ROBLOX Terms of Service. If a user did not provide an alternate name, the username would then be changed to [ Content Deleted NUMBER ] for usernames changed prior to 2014 or ResetUserID for names changed after 2014.

A feature released on October 22, 2013, allowed users to voluntarily change their usernames for a 1,000 Robux fee. All usernames that are changed must satisfy all username requirements and policies.


Main article: Username/Name sniper

Namesniping is an activity people do to find rare or lucky names only earlier people could get. For example, "Player" is an example of a namesnipe. Most accounts are made for the purpose of taking the name before somebody else can; these accounts are often left inactive or rarely used. Certain groups also have communities that are dedicated to namesniping, which perpetuates the trend.

December 2016 exploit


A fake "ROBLOX" account created using the exploit. The name of this account changed to Reset190990774 before it was terminated.

In December of 2016, there was an exploit where people could make a new account that was the same name a different user, "David " and "David" for example. and people also used this to make 2 letter accounts, such as "pi " and "hi ". This was patched days after the exploit was discovered and all users that were made with the exploit were deleted. At the same time, users were also able to create users with a dash in their name, e.g. Builder-Guy. All users with dashes in their name got reset.

    • You can't. But we should be able to. People could still find your account once you change it.
