What Is a Facebook UID?
Every Facebook profile, page, and group is assigned a unique numeric identifier called a Facebook UID (User ID). While your display name or custom username (vanity URL) can be changed at any time, your UID remains permanently tied to your account from the moment it is created.
This numeric ID is what Facebook's internal systems, Graph API endpoints, and third-party integrations actually use behind the scenes to identify accounts. For developers building chatbots, marketers setting up ad tracking pixels, or analysts pulling social media data, having the correct UID is not optional — it is essential.
However, Facebook does not display this number anywhere on the public profile page. That is exactly why this tool exists: to bridge the gap between a visible profile URL and the hidden numeric ID that powers it.

Common Use Cases
Facebook UIDs are required across a wide range of professional and technical scenarios. Software developers need them to make Graph API calls for building Facebook-connected applications, chatbots, and automation workflows. Without the correct numeric ID, most API endpoints simply will not respond.
Digital marketers and media buyers use UIDs to create custom audiences for ad targeting, verify pixel installations, and connect CRM data with Facebook ad platforms. Many third-party marketing tools explicitly ask for the profile ID number rather than a URL.
Security researchers and OSINT analysts rely on UIDs to cross-reference accounts across platforms, track public page metadata, and investigate potential impersonation or fraudulent profiles. The UID is the most reliable anchor point for any account investigation.
Whether you are a solo developer, part of a marketing team, or simply curious about the technical side of Facebook, this tool gives you the exact number you need without any unnecessary complexity.
