What should you know before you start?
| Fact | What it means |
|---|---|
| One change a month | You can change your username once every 30 days, and it changes your profile link |
| Given-up names wait | A username you give up can't be used again for a short period |
| Inactive accounts | TikTok can reclaim and reassign a username after 180 days without a login |
| Age | In the US, under-13s (under-14s in Florida) can only use a separate, limited experience |
What can go wrong, and how do you fix it?
| Problem | Fix |
|---|---|
| The username looks unused but is unavailable | A suspended or deactivated account may hold it. Use a close version (what to do when your handle is taken) |
| You can't change your username | You've changed it in the last 30 days, or your profile is blocked from updates |
| A period at the end is rejected | Move or remove it; periods can't end a username |
| A sound isn't available to your business | Business and Organization accounts can only use the Commercial Music Library |
