Overview
Your Roblox @username is the unique handle friends and marketplaces use. Your display name is cosmetic and can collide with thousands of other players — never treat it as proof of identity.
Before buying on Mystery Market, confirm the delivery @username with our checker so staff trade the right account.

Steps
- 1
Know username vs display name
Username: unique, used in profiles and trades, limited character set. Display name: shown above your head, changeable more freely, not unique. Scammers love lookalike display names that mimic popular traders.
- 2
Pick a durable username
Favor readable letter–number mixes you can type under pressure. Avoid leetspeak that looks like phishing (rn/m, Il1). Underscores help availability; spaces are not allowed in usernames.
- 3
Check availability first
Use /tools/username-checker before you spend a rename. If it is taken, note the user ID so you do not confuse two similar handles later.
- 4
Change display name in settings
On Roblox: Settings → Account Info (or Account Settings) → Display Name. Follow Roblox’s cooldown rules. Changing display name does not change your @username or inventory.
- 5
Update marketplace delivery info
If you renamed your username (not just display name), update any open Mystery Market orders and tell support before delivery. Staff target the username on the order — not your old brand.
Tips
- Write your @username on paper before checkout — phone autocorrect invents wrong handles.
- Alts need separate usernames; do not reuse the same delivery name across accounts you no longer own.
- Offensive or impersonation names can be moderated by Roblox even if they appear available.
FAQ
- Can two people share a display name?
- Yes. That is why trades and shop delivery must use the unique @username.
- How often can I change my Roblox username?
- Roblox applies its own rename limits and may charge Robux for username changes. Check the official account settings for the current rule on your account.
- Will changing my display name break a Mystery Market order?
- No — we deliver to the @username on the order. Display name changes are cosmetic only.
