Facebook UID checker

Understand what the result means

This endpoint answers one question: does this UID have a public profile photo. Found means the profile exists. Not found has two causes — the UID does not exist, or the account is alive with no photo — and they are indistinguishable.

Which is why we do not print "dead". Reporting "I could not tell" as "it is dead" makes people discard working accounts and return sound goods. Rate-limited rows are likewise "cannot tell", not a status.

The only way to know an account is usable is to log in yourself, which is exactly what the warranty window is for.

What does this actually prove?

Exactly one thing: that the UID resolves to an image on Facebook's public profile-picture endpoint. That means the profile exists. It does not mean the account is unrestricted, loggable-in, or able to run ads.

Does "no photo found" mean the account is dead?

No. The default silhouette has two possible causes: the UID does not exist, or the account is alive with no photo set. This endpoint cannot distinguish them, so we do not label it "dead".

Why do some rows say "cannot tell"?

Facebook rate-limits unauthenticated requests and responds with "an access token is required". That is a rate-limit response, not an account status. Retry those in a few minutes.

Do I need to enter a password?

No — and you should not enter one into any tool. This queries a public endpoint and needs only the UID. Any service requiring your password to "check" an account has, in effect, taken the whole account.

How many can I check at once?

Fifty. More gets rate-limited and the whole batch turns into "cannot tell" — that is fewer results, not more.

Where do I find the UID?

The digits in a profile URL like facebook.com/profile.php?id=XXXX. You can also paste a whole credential string and the tool will pull the leading number.
