Instant Username Search vs AliaScan — FAQ
Is Instant Username Search the same as AliaScan?+
No. Instant Username Search shows whether a handle is free to register. AliaScan does the opposite: it finds the public profiles that already use that handle and gives you a direct link to each.
How do I find who owns a username instead of just checking availability?+
Use AliaScan. Availability checkers stop at green or red; AliaScan checks 400+ platforms and returns the actual profile URLs so you can see who is behind the handle.
