The short version: Your Facebook Page ID is the long string of numbers Meta uses to identify your page behind the scenes, and you’ll find it fastest through Meta Business Suite settings, the Page Transparency section, or by viewing your page’s source code. It matters because almost every tool you connect to your page, from ad platforms to chatbots to review widgets, needs that number, not your page name, to work correctly.
What a Facebook Page ID is
Every Facebook Page gets assigned a unique numeric ID the moment it’s created. It looks something like 104582398471203. It has nothing to do with your page name, your custom URL, or your username. You could rename your page five times, and that number would never budge.
That’s the bit most people get wrong. They think the vanity URL (facebook.com/yourbusinessname) is the identifier. It isn’t. It’s a label sitting on top of the real ID, and Facebook lets you change that label whenever you like, which is exactly why I wrote a full piece on how to change your Facebook page name without losing followers. The name is cosmetic. The ID is structural. Confuse the two and you’ll spend an afternoon debugging something that was never broken.
Where to find it in 2026 (four methods, ranked by speed)
Facebook has redesigned the Page settings menu at least four times in the last five years, so half the tutorials floating around online reference buttons that no longer exist. Here’s what works right now.
1. Meta Business Suite (fastest, works every time)
- Log into business.facebook.com or open Meta Business Suite from your page.
- Click your page name in the top left, then go to Settings.
- Select “Page settings” or scroll to the “About” section.
- Your Page ID sits right under the page name, usually labelled clearly as “Page ID”.
2. Page Transparency
- Go to your Facebook page as a visitor would see it.
- Scroll down the left column (or the About tab on mobile) until you see “Page Transparency.”
- Click “See All.”
- Your Page ID is listed there along with when the page was created and any name changes it’s had.
I prefer this method for client audits because it also shows me if a page has changed names or merged with another one, which tells me a lot about its history before I agree to touch its ad account.
3. View page source
- Right-click anywhere on your Facebook page and choose “View Page Source” (or Ctrl+F / Cmd+F in the developer tools).
- Search for “pageID” or “entity_id”.
- The number sitting next to it is your Page ID.
This one’s a bit technical but it’s the fastest way if Meta has hidden the Transparency section behind a login wall you can’t access, which happens more often than it should.
4. Graph API Explorer
- If you’re a developer or you’re setting up an integration, go to developers.facebook.com and open the Graph API Explorer.
- Select your page from the dropdown and run a GET request on “me”.
- The response returns your Page ID as JSON.
Nobody needs this method unless they’re building something custom. But if your web developer asks for it, this is what they mean.
Why this tiny number runs more of your business than you’d think
I once had a client, a physiotherapy clinic in Surrey, whose Facebook ads suddenly stopped delivering. Spend was sitting at zero, impressions flat, and their in-house marketing person swore nothing had changed. Turns out someone had swapped their connected page inside Ads Manager during a rebrand, picking a near-identical page name from a dropdown list that had two entries looking almost the same. Same logo, similar name, wrong page. Wrong Page ID. Every ad they’d built pointed at a page with 40 followers instead of their real page with 6,000.
It took eleven minutes to fix once we pulled the correct Page ID from Page Transparency and reconnected it. It took three weeks for someone to notice the ads weren’t working in the first place, because the campaign still looked “live” in the dashboard. That’s the uncomfortable bit nobody tells you: Facebook won’t warn you when your ads are technically running but pointed at the wrong asset. It just quietly under-delivers and lets you assume it’s an algorithm problem.
Here’s where the Page ID earns its keep:
- Ad account connections. Ads Manager, Meta Business Suite, and any agency running your campaigns all use the Page ID to know which page an ad is posting from and which page’s likes and comments belong to which campaign.
- Third-party tools. Chatbot builders like ManyChat, scheduling tools, review aggregators, and CRM integrations (think HubSpot or Zapier) almost always ask for a Page ID during setup rather than a name, because names change and IDs don’t.
- Website plugins. If you’ve embedded a Facebook feed, reviews widget, or “like box” on your website, it’s pulling data using your Page ID, not your URL.
- Facebook Pixel and Conversions API. Advanced tracking setups reference the Page ID alongside the Pixel ID to attribute leads and sales.
- Merging pages. If you’ve got a duplicate page created by mistake (extremely common when a well-meaning employee sets up a second page for the same business), Facebook needs both Page IDs to process a merge request.
The confusion that wastes the most hours
Nearly every support ticket I see about “my Page ID isn’t working” is a case of someone grabbing the wrong ID entirely. There are at least four different numeric IDs floating around a typical Facebook business setup, and they get swapped constantly:
- Page ID identifies the page itself.
- Profile ID identifies a personal Facebook account (yours, or an admin’s), completely separate from any page.
- Ad Account ID identifies the billing and campaign structure inside Ads Manager, which can run ads for multiple pages.
- Business Manager ID (now called Business Portfolio ID) identifies the entire Meta Business Suite account that might hold several pages, ad accounts, and Instagram profiles under one roof.
Developers building an integration will ask specifically for “Page ID,” and if you hand over your Business Portfolio ID instead, the whole setup fails silently or connects to the wrong asset. This is one of those things nobody flags clearly because it feels too basic to write about, but it’s the single most common reason a Zapier automation or chatbot integration doesn’t fire. If a setup guide asks for an ID and something isn’t working, the first thing to check isn’t the tool, it’s whether you copied the right number from the right settings screen.
When you’ll need to dig this number up
Most page owners go years without ever needing their Page ID directly, because Facebook handles the connections for you inside its own interface. You’ll need it specifically when:
- You’re setting up a third-party scheduling or chatbot tool that asks for it during integration.
- Your web developer is embedding a live feed or reviews widget on your site.
- You’re troubleshooting why ads aren’t showing up correctly in Ads Manager.
- You’re requesting a page merge because a duplicate exists.
- You’re auditing a competitor’s page, perhaps alongside checking where to see all the Facebook ads a business is running, and want to confirm you’re looking at their real page rather than an impersonator account.
- You’re changing your page’s category and want to confirm the ID stays fixed across the change, which it will, unlike your visible category tags covered in my piece on Facebook page category options and which to pick.
What happens if you use the wrong one
The clinic story above is the mild version. I’ve also seen a coaching business accidentally connect a client testimonial widget to a page they’d stopped using two years earlier, meaning every new testimonial submitted through their website vanished into an inactive page nobody checked. Three months of reviews, gone, because the widget was still pointing at an old Page ID nobody had bothered to update after switching pages.
The pattern is always the same: something looks connected, everything appears to be working on the surface, and the actual data flow is broken because it’s pointed at the wrong identifier. None of these tools throw an obvious error message. They just quietly serve up nothing, or worse, serve up the wrong page’s data, and you don’t notice until someone asks why the numbers don’t match reality.
My rule for clients now is simple: whenever we connect a new tool to a Facebook page, we screenshot the Page ID from Page Transparency at the same time, date it, and store it in the same folder as login details. Takes thirty seconds. Saves hours of “why isn’t this working” later.

Frequently asked questions
Does my Facebook Page ID ever change?
No. The Page ID is permanent from the moment the page is created and stays the same even if you rename the page, change its category, or update its custom URL. The only time it changes is if Facebook merges your page into a completely different one during a duplicate-page merge, which creates a new combined ID.
Is my Page ID the same as my Facebook username or vanity URL?
No, and this is where most confusion starts. Your username (like facebook.com/yourbusiness) is a customisable label you can change in your page settings. Your Page ID is a fixed number underneath it that Facebook’s systems use to identify the page. Tools and integrations almost always need the number, not the username.
Can two Facebook pages have the same Page ID?
Never. Every Page ID is unique to one page, which is exactly why it’s the reliable identifier for connecting ad accounts, plugins, and integrations. If you’re seeing conflicting data between two pages that should be the same business, check whether you accidentally created a duplicate page with its own separate ID.
Do I need my Page ID to run Facebook ads?
You don’t need to manually enter it for standard ad creation inside Ads Manager, since Facebook selects the page for you from a dropdown. But if you’re troubleshooting delivery problems, connecting a third-party ad management tool, or working with an agency who asks for it directly, having your Page ID on hand speeds everything up and removes the risk of the wrong page getting selected.
