Live UID Checker
Check if Facebook UIDs are live or dead in bulk — real-time results, no login needed.
About Live UID Checker
Our free Facebook UID checker tells you whether Facebook user IDs are live or dead — in bulk and in real time. Paste up to 1,000 UIDs and get a clear LIVE or DEAD result for each one, with a progress bar, summary counts and one-click copy buttons for the live and dead lists.
The check runs through our secure server, so there is no Facebook login, no access token and no app setup required. Advertisers use this live UID checker to clean audience lists, and marketers use it to verify scraped or purchased UID data before spending money on it.
Live UID Checker — FAQs
What does LIVE or DEAD mean in the UID checker?
LIVE means the Facebook UID currently resolves to a real, accessible object. DEAD means it does not resolve — the account may be deleted, disabled or otherwise unavailable.
How many UIDs can I check at once?
You can paste up to 1,000 UIDs per run. Larger lists are automatically split into smaller batches and processed one after another with a live progress display.
Do I need a Facebook login or access token?
No. The check runs server-side through our own endpoint, so you never enter Facebook credentials or tokens.
Why would a UID show as dead?
A UID can stop resolving if the account was deleted or disabled by the user or by Facebook, or if the ID was never valid. The tool reports what the endpoint returns; it cannot tell you the exact reason.
