Our Story

Every developer who has worked with the Facebook Graph API knows the frustration: you have a profile URL or username, but you need the raw numeric User ID to make API calls, configure ad audiences, or set up a Facebook Login integration. Finding it used to mean digging through page source code, browser developer tools, or third-party apps of questionable reliability.

We built findfbid.com to solve that problem in one clean lookup. Paste in a URL, a username, or a numeric ID — and get the permanent UID back in seconds. No account required on your end. No complicated setup. Just the answer.

Since launching, the tool has grown to support personal profiles, Facebook Pages, people/ URLs, and profile.php?id= links — with smart input normalisation that handles whatever format you throw at it.

How It Works

You submit a profile URL, username, or numeric ID

The tool accepts any format — a plain username like zuck, a full URL like facebook.com/zuck, a numeric ID like 4, or a profile.php?id= link. All inputs are normalised automatically.

We fetch the public Facebook mobile page

Our server makes a request to Facebook's publicly accessible Touch endpoint — equivalent to visiting the profile in a mobile browser. No private data is accessed at any point.

We extract the UID from the page source

The server-side PHP resolver scans the returned HTML for known UID patterns embedded in Facebook's page markup and JSON data islands, then returns the numeric identifier.

You get the result instantly

The UID, display name, and profile picture are shown on-screen. Results are cached server-side for 24 hours so repeat lookups are near-instant. One click copies the UID to your clipboard.

What Makes It Different

Flexible Input

Accepts usernames, full URLs, schemeless URLs, numeric IDs, profile.php links, and people/ URLs — no need to clean up your input first.

Fast & Cached

Server-side result caching means repeat lookups return in milliseconds. Fresh lookups typically complete in under two seconds.

No Login Required

You never need a Facebook account or any credentials. Just paste and look up — nothing to install or sign in to.

Profile Picture

The tool resolves the highest-resolution publicly available profile photo alongside the UID and display name.

One-Click Copy

Hit Copy and the UID is on your clipboard — no fiddly text selection needed.

Completely Free

No subscriptions, no API keys, no rate-limit paywalls. The full tool is free to use for everyone.

Our Values

We built this tool with a small set of principles we hold ourselves to:

  • Transparency. We publish a clear Privacy Policy and Terms of Service. We tell you exactly what data we collect and why.
  • Privacy by default. We do not log, link, or sell the profile inputs you submit. Your lookups are your business.
  • Legitimate use only. The tool is built for developers, marketers, and researchers working with public data. We actively discourage any use that could harm individuals.
  • Simplicity. One input, one result. We resist the urge to bloat the tool with unnecessary features or dark-pattern upsells.
  • Reliability. We maintain the tool actively, updating patterns and headers as Facebook evolves so it keeps working when you need it.
