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 and can later change it for 1,000 Robux.


During the early stages of Roblox, usernames could have spaces in them, such as John Doe and Jane Doe, this feature was later removed on December 21, 2006 due to users impersonating other users by using spaces, and using their full names to create their username.

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 from 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.

In 2019, a new mobile feature made it that when you made an account, you would have the username "Robloxian" consisting with 9 random numbers right after it. This was a mobile featured added between early June or July 2019.

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

More [ Content Deleted] Usernames.

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.


This is what a Account Deleted Usernames looks like.

Since fall of 2018, most [ Content Deleted ] names have been replaced with [ Account Deleted (PROFILE ID)]. This has been discovered in October 2018, through a user following several of these names. In 2019, inappropriate usernames are now replaced with "Reset[UserID].

Name sniping

Name sniping is an activity people do to find rare or lucky names only earlier people could get. For example, "Player" is an example of a name snipe. 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 name sniping, which perpetuates the trend. However, this has caused many name snipe accounts to be terminated, due to users password guessing these accounts especially for selling them or showing off in these groups. Usernames with spaces in them are the main targets of password guessing.

Username trends

Aside from name sniping, people often use username trends to make a unique name for themselves and still take the idea of name sniping or adding initials before a name. A list of popular name trends:

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 2016, there was an exploit that allowed new accounts to be created with the name of another, such as by making the accounts "David " and "David". 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 (or hyphen) in their name, e.g. Builder-Guy. All users with dashes in their name got reset.

Usernames with 21+ characters

User with 21+ letters.

User with 50 letters.

In Roblox, it is possible to have usernames with 21 or more letters using glitches. These usernames mostly occur in Xbox-related profiles.

In 2011, an iOS glitch allowed people to create accounts with a username consisting up to 50+ characters.

  • Oddly, before the forums were removed, when changing usernames the username you had when you posted a comment on the forums still remained as your previous username.
