TikTok Username Availability Checker
Check whether a TikTok username is available right now, and whether the matching handle is still free everywhere else your audience will look. One name, every platform, one search.
TikTok username rules
A TikTok username can be up to 24 characters and uses only lowercase letters, numbers, underscores, and periods, with the rule that a period can't be the final character. Usernames must be unique across TikTok, and you can change yours only once every 30 days, so a rebrand needs planning. Your username is separate from your display name, which you can edit freely.
What to do if your TikTok name is taken
If a TikTok handle is taken, a period or underscore variant such as "your.brand" or "yourbrand.co" often stays clean and searchable. Because the 30-day change limit makes flip-flopping painful, pick a name you can keep, and confirm it is free on Instagram, YouTube, and your domain first using the search above.
Frequently asked questions

How often can I change my TikTok username?
Once every 30 days, so choose a handle you intend to keep.
