What Is a Facebook ID, How to Find It & Why It Matters
A Facebook ID is a unique, permanent numeric identifier assigned to every entity on Facebook — pages, personal profiles, groups, events, and apps. Unlike usernames or vanity URLs (such as facebook.com/YourBrandName), which page owners can change at any time, the numeric Facebook ID never changes. It is the definitive reference point for any Facebook entity across all of Meta's platforms and APIs.
Why do you need your Facebook Page ID? The Facebook Page ID is essential for a wide range of technical and marketing tasks. Installing the Facebook Pixel on your website requires your Page ID or Ad Account ID. Setting up the Facebook Chat Plugin (formerly Customer Chat) embeds on your website demands the exact numeric Page ID. Facebook Business Manager uses numeric IDs to link pages, ad accounts, and pixels. Developers using the Facebook Graph API must reference entities by their numeric ID for all API calls, data retrieval, and webhook configurations.
How to validate a Facebook ID: A valid Facebook ID typically consists of 10 to 25 digits with no letters, spaces, or special characters. You can validate any numeric ID through the Graph API Explorer at developers.facebook.com by querying the ID directly. Our tool displays the extraction method used alongside each ID — such as "og:url meta tag" or "entity_id (JSON)" — giving you confidence in the accuracy of the result.
Finding IDs for private or restricted profiles: If a Facebook profile is set to private, or if Facebook detects automated access and serves a login wall, our tool will flag this clearly in the results. For private profiles, the most reliable method is to check your own Facebook Page Settings under the "About" section, where the numeric Page ID is listed directly. For profiles you manage, you can also find IDs in Facebook Business Manager under Page Info, or via the Graph API with an appropriate access token.
Whether you're a developer integrating Facebook services, a digital marketer setting up ad campaigns, or an agency managing multiple client pages, this free Facebook ID Finder saves time and eliminates the need to manually inspect page source code or navigate complex settings menus.
