Your Facebook Page ID is the unique numerical identifier Facebook assigns to your page. Every page has one. You almost never need to think about it until you do, at which point you need it fast and the answer is non-obvious.

This post covers the three ways to find your Page ID in 2026, why you might need it, and a few common gotchas.

When you need your Page ID

You need your Page ID when:

You do not need your Page ID for:

If a tool asks you to paste a Page ID, you need it. Otherwise probably not.

Method 1: The Page's About section (easiest)

On the web:

  1. Go to your Facebook page
  2. Click About in the left sidebar (or scroll down on mobile)
  3. Scroll to the bottom
  4. Find the "Page ID" or "Page transparency" section
  5. Copy the number

This works for pages you own and pages you do not own. It is the easiest method.

On mobile in the Facebook app:

  1. Open your page in the Facebook app
  2. Tap the three-dot menu
  3. Tap About
  4. Scroll to Page transparency
  5. The Page ID is listed

Method 2: The Page URL (sometimes works)

If your page has a numerical URL like `facebook.com/123456789012345`, that number is your Page ID. Done.

If your page has a custom username like `facebook.com/yourpagename`, the URL itself does not contain the ID. You need to use Method 1 or Method 3.

Most older pages have numerical URLs. Most newer pages and pages with custom usernames do not.

Method 3: Graph API Explorer (for power users)

If you are setting up a tool that needs your Page ID along with an access token anyway, the Graph API Explorer gives you both at once.

  1. Go to developers.facebook.com/tools/explorer
  2. Select your app and generate a User Token with `pages_show_list` permission
  3. Make a GET request to `/me/accounts`
  4. The response is a JSON list of your pages with their IDs and names

This method also gets you the page access tokens you need for tools that operate via the Graph API directly. See our separate guide on getting Facebook page access tokens manually for the full walkthrough.

Common gotchas

Page ID vs Username vs URL. These are three different things. Your username is the custom name like "BrandonsBakery". Your URL is the address. Your Page ID is the numerical identifier. Tools that ask for "Page ID" want the number, not the username.

Multiple IDs for one entity. A Facebook page and a corresponding Facebook profile linked to it are two different things with two different IDs. If you have a Page that was converted from a Profile, both exist. Use the Page ID, not the Profile ID, for page management tools.

Business Manager pages. Pages owned by Business Manager have the same Page ID as personally-owned pages. The ownership structure does not affect the ID. But not all tools see BM-owned pages even with the correct ID. If you copy your ID into a tool and the tool says "page not found", the issue is probably the tool's BM support, not your ID.

Page transparency hiding. Some pages have page transparency restricted. If you cannot find the Page ID in the About section, you may need to use Method 3 (Graph API Explorer) instead.

What to do with your Page ID

Once you have it, common uses:

Connecting third-party tools: Paste it into the tool's "Add Page" or "Connect Page" field along with your page access token.

Filing support tickets: Include the Page ID in your message so Meta support knows exactly which page you mean.

Using Graph API directly: All Graph API calls related to your page use the Page ID as the path segment, like `GET /{page_id}/posts`.

Backing up data: If you export page data or download backups, the file names usually reference the Page ID.

For most operators in 2026, the Page ID matters mainly for setting up scheduling tools. After initial setup it lives in the tool's config and you rarely think about it again. See our guide on scheduling posts to multiple Facebook pages for the broader workflow.

Multiple pages, multiple IDs

If you run multiple pages, you have multiple Page IDs. There is no "master ID" that controls all of them. Each page is independent at the ID level.

For multi-page operators, the workflow is usually:

  1. Find each page's ID (Method 1)
  2. Generate a page access token for each (Method 3 or via your scheduling tool's OAuth)
  3. Connect each one to your tools individually

Tools built for multi-page operators (Facebook Auto Poster included) handle this connection step in bulk via OAuth and never make you paste individual Page IDs. Tools that require manual Page ID entry for each page are usually built around a single-page model and feel clunky when you have more than 2-3 pages.
