How the Whistlr username checker works
Type any handle and we check it against live Whistlr accounts instantly. A username is available if no existing profile uses it. Whistlr usernames are 3–20 characters and can include letters, numbers, and underscores. The check runs as you type, so you can try a dozen ideas in seconds without creating an account first.

| Do | Avoid |
|---|---|

| Match your name on other platforms | Hard-to-spell substitutions |
