Every Facebook profile, page, and group has a unique User ID (UID) that operates behind the scenes. This powerful number is essential for advanced marketing, app development, and data analysis. This guide, TuDongChat will show you two easy ways to Find UID for any Facebook account: using a simple online tool or a quick manual check.

What is a Facebook UID & Why It Matters?

A Facebook UID is a unique string of numbers that serves as a permanent identifier for a specific profile, page, or group. Think of it as a social security number for a Facebook entity. While you might see a custom username like facebook.com/yourbrand, the platform’s backend systems rely on the UID to identify that account. For these reasons, knowing how to Find UID is a critical skill for many online professionals.

So, why does it matter?

• Advanced Ad Targeting: Marketers use lists of UIDs to create highly specific Custom Audiences for Facebook Ads, ensuring their message reaches the most relevant people.
• Application Integration: Developers need UIDs to connect their apps and websites with Facebook, enabling features like social logins and data permissions.
• Data Analysis: Researchers and analysts use UIDs to track user engagement, group activity, and page performance without relying on changing usernames.
• Streamlining Workflows: Quickly identifying accounts with a stable ID is crucial for managing large communities or running extensive marketing campaigns.

Method 2: Manually Find Facebook UID

If you prefer a hands-on approach or want to see where the UID comes from, you can find it manually. This method is more technical and time-consuming but is still effective for those who want to Find UID without a tool.

For Profiles with Numeric URLs

Some older Facebook accounts that never set a custom username (a “vanity URL”) have their UID directly in the web address. This is the most straightforward manual case.

For example, if the URL is https://www.facebook.com/profile.php?id=100001234567890, the UID is 100001234567890.

For Custom Usernames (Vanity URLs)

Most modern profiles use a custom URL (e.g., facebook.com/john.smith). To find the UID for these accounts:

1. Navigate to the person’s profile page.
2. Right-click on a blank space on the page and select “View Page Source” from the menu.
3. A new tab will open with the page’s HTML code. Press Ctrl + F (on Windows) or Cmd + F (on Mac) to open the search box.
4. Type “entity_id” into the search box and press Enter. The long number that appears next to it is the profile’s UID.

For Facebook Fanpage

Just like personal profiles, most business or brand Fanpages use a custom username. The manual process for finding a Fanpage’s UID is nearly identical to finding it for a profile. Simply navigate to the Fanpage, use the “View Page Source” method, and search the HTML code for the term “entity_id” to locate the page’s unique identifier.

For Facebook Groups

A group’s UID is often visible directly in its URL, such as facebook.com/groups/123456789012345/. If the group uses a custom name in the URL, you can use the “View Page Source” method and search for “groupID” to find the correct identifier.
