About
Resolves a Facebook username or profile URL to a numeric UID so you can live-check or look up friend count next.
How to use
One username or https://www.facebook.com/... URL per line.
What this tool can do
Turns a username or profile URL into a UID, and may include name and profile URL. Use it before the other Facebook tools.
How to read the results
An empty uid column means the lookup failed. name is the public display name and may differ from the username you typed.
Limits and data handling
Premium lookup. It only resolves public profile identifiers and does not log into Facebook.
FAQ
What input is supported?
Short usernames such as zuck, or facebook.com profile URLs. Numeric UIDs do not need this tool.
Why does lookup fail?
The username changed, the page does not exist, the URL is not a profile, or upstream cannot resolve it right now.
Do UIDs change?
Numeric UIDs are usually more stable than usernames, but the result is still whatever upstream returned this time.
