Username rules
| Rule | TikTok | |
|---|---|---|
| Maximum length | 30 characters | 24 characters |
| Allowed characters | Letters, numbers, periods, underscores | Letters, numbers, periods, underscores |
| Periods | Not at the end, and not two in a row | |
The generator also avoids a period at the start and names made only of numbers. Whether a username is free can only be checked in the app itself; this tool never contacts Instagram or TikTok.
How to pick a good username
- Short and easy to say: people should be able to type it after hearing it once.
- Same on every platform: pick one that is free on Instagram, TikTok and X, so people find you everywhere.
- Avoid long strings of numbers and underscores: they look like spam accounts.
- Match the niche: a word from your topic tells visitors what to expect.
Make the name stand out in your bio with the Instagram font generator. Need an account with history? See aged Instagram accounts and TikTok accounts.
