About Facebook User ID Lookup
The Facebook User ID Lookup tool helps you find the unique numeric ID associated with any public Facebook profile, page, or group. While Facebook displays usernames and custom URLs, every account has a permanent numeric identifier (like 4 for Mark Zuckerberg). This ID is essential for developers, marketers, and anyone who needs to work with the Facebook API or integrate Facebook features into their applications.
How to Find Your Facebook ID

Navigate to the Facebook profile, page, or group you want to look up. Copy the URL from your browser address bar, or note the username shown after facebook.com/.
→Enter the URL or username
Paste the full URL or type just the username into the input field. The tool accepts multiple formats including full URLs, mobile URLs, and simple usernames.
→Click the lookup button
Click the Find Facebook ID button to start the lookup process. The tool will connect to Facebook and extract the numeric ID.
→Copy your Facebook ID
Once found, your Facebook numeric ID will be displayed prominently. Use the copy button to copy it to your clipboard, or use the provided direct link to verify the profile.
What is a Facebook User ID?
A Facebook User ID is a unique numeric identifier assigned to every Facebook profile, page, and group. While users typically interact with Facebook using usernames or custom URLs (like facebook.com/zuck), the underlying system uses these numeric IDs to identify accounts. This ID remains constant even if the username changes, making it a reliable way to reference Facebook accounts programmatically.
For example, Mark Zuckerberg's Facebook ID is 4, as he was among the first users to create a Facebook account. Regular users have much longer IDs, typically consisting of 15-16 digits.
Why Would I Need to Find My Facebook ID?
Facebook IDs are essential for several use cases:
- Facebook API Integration: Developers need numeric IDs to query the Graph API for user data, posts, photos, and other information. The API primarily works with numeric IDs rather than usernames.
- Facebook Pixel and Advertising: Setting up custom audiences, conversion tracking, and retargeting campaigns often requires the Page ID or User ID.
- Social Plugins: Embedding Facebook Like buttons, comment widgets, or Page plugins on your website requires the Page ID for configuration.
- Data Migration and Backup: When backing up or migrating Facebook data, the numeric ID helps maintain consistent references across different systems.
- Customer Support: When contacting Facebook support about account issues, providing your numeric ID can help them locate your account faster.
- Permanent Profile Links: Creating links using numeric IDs ensures they work even if the username changes, like
facebook.com/profile.php?id=123456789.
What URL Formats Does This Tool Accept?
This tool accepts multiple formats to make finding Facebook IDs as convenient as possible:
- Simple username:
zuck - Full URL:
https://www.facebook.com/username - Mobile URL:
https://m.facebook.com/username - Short URL:
fb.com/username - Profile URL with ID:
facebook.com/profile.php?id=123456789 - Page URLs:
facebook.com/pages/PageName/123456789 - Group URLs:
facebook.com/groups/groupname
The tool automatically extracts the username or ID from any valid format, so you do not need to manually clean the URL before searching.
Understanding Facebook Profile Types
Personal Profiles
Personal Facebook profiles are individual user accounts. These profiles have privacy settings that may affect whether their ID can be retrieved. Public profiles allow ID lookup, while private profiles with strict settings may not return results.
Facebook Pages
Facebook Pages are public profiles for businesses, brands, celebrities, causes, and organizations. Page IDs are essential for managing the page through the Graph API, setting up Facebook Business Suite, and integrating page features on external websites.
Facebook Groups
Facebook Groups also have unique numeric IDs. Group IDs are useful for group management tools, analytics platforms, and integrations that work with group content.
Common Issues and Troubleshooting
Profile Not Found
If the tool cannot find a profile, check that:
- The username or URL is spelled correctly
- The profile is public and accessible without logging in
- The account has not been deactivated or deleted
- You are not trying to access a profile with strict privacy settings
Request Timeout
Timeouts can occur when Facebook servers are slow or experiencing high traffic. Try again in a few moments if you encounter this error.
Rate Limiting
Facebook may temporarily block requests if too many lookups are performed in a short time. Wait a few minutes before trying again if you encounter this issue.
Privacy and Security
This tool is completely safe and respects user privacy:
- No Data Storage: We do not store any search queries, results, or personal information. Each lookup is processed in real-time.
- Public Data Only: The tool only retrieves publicly available information that anyone can see by visiting the Facebook profile.
- No Login Required: You do not need to provide your Facebook credentials. The tool works by accessing public profile pages.
- Secure Connection: All communications are encrypted using HTTPS to protect your queries.
Technical Details
When you enter a Facebook URL or username, the tool:
- Parses and normalizes the input to extract the username or ID
- Requests the public Facebook page for that username
- Parses the page source to find the numeric ID in the metadata
- Returns the ID along with verification links
The numeric ID is embedded in the page source of every public Facebook profile, making it accessible without requiring API authentication.
