What is a TikTok User ID?
A TikTok User ID (also called UID or sec_uid) is a unique numeric identifier assigned to every TikTok account. It is different from the visible username (which starts with @) and remains unchanged even when the user updates their display name or handle.
TikTok UIDs are essential for developers integrating with the TikTok API, brands managing creator partnerships, social media tools that track account data, and researchers studying content trends on the platform.

What's the difference between TikTok UID and username?
The username (e.g. @dancequeen) is a custom handle chosen by the user. The UID is a permanent numeric ID (e.g. 6842123456789) assigned by TikTok's system.
