TikTok Username Syntax & Validation Rules

Before querying the API, validate candidate handles against ByteDance's official unique_id character constraints:

Validation RuleSpecificationEngineering Notes
Character Length2 to 24 charactersHandles shorter than 2 characters or longer than 24 characters are rejected by TikTok registration.
Allowed CharactersLetters (a-z, A-Z), digits (0-9), underscores (_), periods (.)Spaces, hyphens (-), emojis, and special symbols (@, $, !) are not permitted inside unique_id.
Trailing Period RestrictionCannot end with a period (.)Periods are allowed in the middle of a username (e.g. khaby.lame) but never as the final character.
Numeric-Only RestrictionCannot be all digitsUsernames must contain at least one letter, underscore, or period so they do not collide with numeric user_id.
Change CooldownOnce every 30 daysWhen a creator changes their @username, the previous handle is released after a cooldown window while their numeric user.id stays constant.

Frequently Asked Questions

How do I check if a TikTok username is available or taken via API?

Call GET https://api.tiktokapi.io/v1/user/info?unique_id=yourhandle with your x-api-key header. If the response returns code === 0 with a populated data.user object, the handle is registered and active. If it returns user not found (and the handle passes TikTok's 2-24 character syntax rules), the handle is currently unregistered.

How much does it cost to bulk check 1,000 TikTok usernames?

Successful profile lookups cost 10 Credits ($0.001 per registered profile at the base rate, or $0.0004 on the Business plan). Even better, non-200 or unfound handle lookups cost 0 Credits under our pay-for-success guarantee.

Why does a TikTok username show as unavailable during signup even when no public profile exists?

If GET /v1/user/info returns no active public profile for a valid handle, the handle is either completely free to register or held in TikTok's 30-day rename quarantine / trademark reservation list.
