Frequently asked questions
How does the TikTok username checker work?
It looks up the public TikTok profile for each name. If no public account exists, the name may be available.
Why does an “available” name not work in the app?
Banned, private-by-default or reserved accounts don’t show up publicly, so TikTok may still reject the name.
How often can I change my TikTok username?
TikTok limits username changes (currently once every 30 days).
