Search username, user ID, or item name
Looks like a Roblox User ID — press Enter or click Check to resolve it to a username automatically.
Enter a Roblox username, a numeric User ID (resolved automatically via Roblox), or an item name to see all known dupers. Search is case-insensitive.

Database Notice: This registry only contains tracked and confirmed dupe records submitted to JBLX. A clean result means we have no record of that username in our database — it is not a 100% guarantee the item is unduped. Duping was patched and only occurred in a limited window; new entries are added when evidence is submitted to the team on Discord.
