What is TikTok?
TikTok launched globally in September 2017 after ByteDance merged its Douyin product with the acquired Musical.ly app. It is the most-downloaded app in the world and counts more than 1 billion monthly active users.
Every TikTok account has two identifiers: a public numeric uid (what IDInfo returns) and a separate signed string called secUid used by some private mobile API endpoints. The numeric uid is what you need for the public Web API, embeds, and the TikTok for Business platform.
How TikTok user IDs evolved
From the very first IDs to today's modern numeric format — here's how the system grew alongside the platform itself.
-
2017
Launch — IDs in the millions
When TikTok launched globally, new accounts received numeric IDs starting in the millions. Early creators like Charli D'Amelio (uid 5831967) ended up with relatively low 7-digit IDs.
-
2019–2020
Crossing the billion-user mark
TikTok exceeded 1 billion downloads in 2019 and 1 billion monthly active users in 2021. Account IDs entered the billions and tens of billions in this period.

2021+
Trillions — 64-bit IDs
Today's newest accounts get IDs in the
7,000,000,000,000,000,000range (19 digits). TikTok uses 64-bit signed integers, giving them billions of years of capacity. -
2022
secUid added for API hardening
TikTok introduced the secUid — a signed string identifier — for some endpoints to thwart abuse. The public numeric uid (what IDInfo returns) remains the canonical primary key.

Why your TikTok ID matters
- TikTok For Business / TikTok Ads: campaign targeting, Spark Ads, and the Marketing API all require the numeric user ID.
- TikTok Embed Player: referenced by uid, so embeds keep working when a creator changes their @handle.
- Brand safety & reporting: third-party measurement tools (DoubleVerify, Tracer) index creators by uid to keep records stable.
- Shop & monetisation: TikTok Shop, Creator Marketplace, and tipping all use the numeric uid as the primary key.
