Roblox Username Generator

The Roblox Username Generator turns a name or a word into up to 20 username ideas in a style you choose, with an optional favorite number and length range. Each result has a copy button and a link that opens the Roblox profile search for that name, so you can see whether it is already registered. It is for new players stuck on the sign-up screen and for anyone paying 1,000 Robux for a rename who wants to get it right.

How it works

1. Enter your name. Your first name, a nickname, your favorite game or item, anything. It is only the seed word; the usernames are built from it, so if you don't want your real name in the handle, don't type it.
2. Select a vibe. Twelve styles: all, professional, nature-inspired, artistic, fantasy, catchy, sporty, cute, tech-inspired, sci-fi, funny and gamer. For Roblox, gamer, fantasy, sci-fi and cute get the most use; the professional style is there because the same engine powers our other username tools.
3. Optional settings. A favorite number, worked into some results, and a length slider from 1 to 32 characters.

Press Generate and the inputs are sent to our username API, which returns a batch; the page shows up to 20. Click again for a new batch with the same settings.

Roblox's username rules

Roblox rejects more usernames than most platforms, partly because of its character rules and partly because of its content filter. The generator does not apply these rules, so run each candidate against them.

• Length: 3 to 20 characters. Set the slider's upper handle to 20.
• Characters: letters, numbers and at most one underscore. The underscore cannot be the first or last character. No spaces, periods or hyphens.
• Filter: names are checked against Roblox's moderation filter. Anything that could be read as a swear word, a personal detail (phone number, address) or a name of a real person may be rejected even if it looks harmless to you.
• Uniqueness: case-insensitive and permanent. A username from a deleted or banned account is not released, so the pool of short names is very small; almost every real word under eight letters is gone.
• Changing it: allowed, but it costs 1,000 Robux each time. Your old name is kept in your "previous usernames" list and cannot be taken by anyone else.
• Display name: a separate, non-unique name shown in games and chat, changeable once every 7 days for free. If you just want a cooler name over your avatar, change the display name and keep the username.

Getting a name that is actually free

Because Roblox has had hundreds of millions of accounts since 2006, a clean single word will be taken. What tends to work:

• Two words, capitalized. FrostedAxolotl, QuietBuilder, NeonPancake. Easy to say in a voice chat and easy to type when a friend adds you.
• A word and a number that means something to you. Use the favorite number setting for this. Avoid your birth year; it tells strangers your age.
• A single underscore between two words if the CamelCase version is taken.
• Invented words from the fantasy or sci-fi vibe, which have almost no collisions.

Skip anything with a long string of digits at the end; it looks like a bot account and other players treat it that way. Also avoid "Rblx", "Official" or "YT" unless you are in fact that.

If you play on other platforms too, the Steam Name Generator, PSN Name Generator and Twitch Name Generator use the same inputs with each platform's rules described, and the Pokemon Nickname Generator is the one for naming in-game creatures rather than your account. The general-purpose Username Generator and the rest of the set are under all name generators.
