TikTok ID Finder — User ID & SecUID

Resolve any username to its TikTok IDs

Need a TikTok account's numeric User ID (UID) or SecUID? Enter the username and we'll resolve it to the account's internal identifiers in seconds — handy for developers, API integrations, data analysis, and OSINT research.

UID vs SecUID — what's the difference?

• User ID (UID): a stable numeric identifier that uniquely and permanently identifies the account, even if the username changes.
• SecUID: a secure, longer token TikTok uses in its API and in profile/share links. Many API calls require the SecUID rather than the username.

Why look up a TikTok ID?

Usernames can change, but the UID does not — so the ID is the reliable way to track an account over time. Developers need the UID/SecUID to call TikTok endpoints, and investigators use it to confirm they're looking at the same account across renames.
