Frequently asked questions
Can I change my TikTok username?
Yes, but TikTok limits how often, so choose carefully.
Is the username the same as the display name?
No. The display name is separate and can be changed more freely.
Where can I check my text length for every platform at once?
Use the social media character counter, which shows the limit for each platform side by side.
