ID Finder for Facebook™
Instantly reveal and copy the numeric ID of any Facebook user, page, group, or post — ideal for developers and marketers
About this extension
ID Finder for Facebook is a simple utility extension that instantly reveals the numeric ID of any Facebook user, page, group, or post. Just visit the profile or page you're interested in, and the ID is displayed right in your browser.
Numeric IDs are essential for developers working with the Facebook Graph API, marketers setting up custom audiences, and researchers who need stable identifiers that don't change when usernames are updated.
No configuration needed — install the extension and it works automatically on every Facebook page you visit. Lightweight, fast, and completely free.
The extension works across all major Facebook entity types — user profiles, business pages, groups, events, and individual posts — displaying the correct numeric ID for each. When you navigate between pages, the displayed ID updates automatically with zero delay, so you can quickly copy IDs for multiple entities in a single browsing session. This is especially useful when setting up Facebook Pixel configurations, building custom API queries, or populating spreadsheets with page identifiers for a bulk marketing campaign. The extension reads IDs directly from Facebook's page data, which means it always returns the accurate, canonical ID rather than an approximation from URL parsing.
Most alternative methods for finding a Facebook ID — such as viewing page source code, using the Graph API Explorer, or relying on third-party lookup websites — are time-consuming and often unreliable as Facebook changes its page structure. This extension eliminates all of that friction by surfacing the ID instantly as part of your normal browsing workflow. Freelance developers building Facebook integrations, digital marketing agencies managing dozens of client pages, e-commerce businesses configuring Facebook Shop connections, and data analysts compiling datasets all save significant time with this utility. Because the extension is completely free, requires no account, and processes everything locally in your browser, there are no privacy concerns about sharing Facebook URLs with external ID-lookup services.
Why You Need This
Developer API Integration
Developers working with the Facebook Graph API need numeric IDs to query user profiles, pages, and posts programmatically. This extension eliminates the manual process of extracting IDs from URLs or API explorers.
Ad Targeting & Custom Audiences
Digital marketers use Facebook numeric IDs to set up custom audiences, track page performance, and configure ad targeting. Having instant access to IDs speeds up campaign setup and audience management.
Social Media Research
Academic researchers and data analysts use numeric IDs as stable identifiers for tracking Facebook entities across studies. Unlike usernames which can change, numeric IDs remain constant over time.
