Tips for picking a Roblox username
Usernames are 3–20 characters, letters and numbers with at most one underscore, and cannot be changed for free — renaming costs 1,000 Robux, so pick one you can live with. If your favourite is taken, adding an underscore or a meaningful number usually finds a free variant. Your display name is the one you can change freely — grab ideas from our display name list or write a matching bio.
