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.[1] Usernames may have 3 to 20 characters, consisting of numbers, letters, and up to one underscore.

History

During the early stages of Roblox, usernames could have spaces in them, such as John Doe and Jane Doe, but 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. During this time a few administrator accounts had periods in the username, this feature was likely only included during Roblox's beta period between 2004 and 2006.

On February 24, 2016, underscores were added back into the allowed list of characters in usernames (the first time since they were initially removed back in December 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 can 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

More [ Content Deleted ] usernames.

Initially, users were only allowed to change their names due to either a parent's 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. When a username is changed, it will often change the color of the name displayed on the in-game chat system.

A feature released on October 22, 2013, allows users to voluntarily change their usernames for a 1,000 Robux fee.[2] This feature was highly requested by the community on the forums ever since Roblox first released. All usernames that are changed must satisfy all username requirements and policies.

Replacement

This is what an Account Deleted username 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]". Recently, on the website, banned users are just displayed with their proper name and avatar, but you can not click on them.


Name sniping

Main article: Username/Name sniper

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:

  • (Name)Playz
  • Xx(Name)xX
  • x(Name)x
  • (Name)HD
  • (Name)Gaming
  • (Name)Gamer
  • (Name)ALT
  • (Name)YT
  • ii(Name)
  • ii(Name)ii
  • Word replaced with letters such as "V", "X", or "Z" (Example: Axsthxtics)
  • UseStarCode_(name)
  • (Name)WasTaken
  • (Double digit number) letter k, (Random word) e.g. 24kglocks
  • (Name)_RBLX
  • (Name)RBLX

For some roleplay games, especially those that revolve around policing, these are also common:

  • (Name)Astria
  • ii(Name)_Law
  • (Name)_Law
  • (City)_Operators
  • (City)_Defenders

December 2016 exploit

123432

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

50username

An account with 50 character. Created using the 2011 iOS exploit.

Username Example

An Xbox tester profile with 21+ characters.

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

The most notable instance of this being possible was in 2011. When Roblox had first released on iOS devices they messed up the character cap. While it is unknown exactly how it was bugged it allowed users to register accounts with up to 50 characters instead of 20. The exploit was eventually leaked on the forums after around a month where it was then patched.

Trivia

This section is a trivia section. Please relocate any relevant information into other sections of the article.

  • Contrary to popular belief, 51 character usernames do not exist. The most characters ever possible were 50.
  • 3 letter usernames ran out on September 14, 2019.
  • 4 letter usernames ran out on July 2, 2020. If a username generator gives you a 4 letter username, it is most likely a username that Roblox finds "inappropriate" and not allowed.
  • There are groups on Roblox that will purposefully change their username to one format (see Username Trends above) in order to be recognisable.
