A Roblox rename costs Robux, so it pays to get the name right before you open the checkout. The generator only builds names Roblox will accept, and you can check each one before you spend anything.

Tips for a Roblox name you won't want to change

  • Use capitals instead of an underscore. You only get one underscore, and FrostByteKid reads as easily as Frost_Byte_Kid would.
  • Remember capitals aren't a free edit. Changing only the capital letters still counts as a full, paid rename.
  • Leave out your real full name and age. Many Roblox players are young, and a username is public in every game you join.
  • Check before you buy. Use the Roblox username checker, then confirm on the Roblox rename screen.

Playing on other platforms too? The Discord username generator and the gamertag generator use the same idea style.

Frequently asked questions

What are the Roblox username rules?

3 to 20 characters, using letters and numbers plus at most one underscore, and that underscore can't be the first or last character. Roblox also filters names it considers inappropriate.

Does it cost Robux to change a Roblox username?

Yes. Every username change costs Robux, and the price is shown at checkout. Your display name is separate and free to change, so if you only want a new look in games, change that instead.

Why does Roblox say a name is not available when nobody uses it?

The name may belong to an old or banned account, or Roblox's filter may block a word inside it. Try a different spelling or move the underscore, then press Check again.

Can I use a period or hyphen in a Roblox name?

No. Only letters, numbers and one underscore are allowed, so the generator never suggests periods, hyphens or spaces for Roblox.
