How to Find a Facebook Page ID for an Advertiser
The fastest way to find a Facebook Page ID is to open the Page, go to the About tab, and scroll to Page transparency, where the ID is listed directly. The Page ID is a permanent numeric identifier that never changes, even when the brand renames the Page or changes its handle.
That permanence is why it matters for ad research. A competitor who rebrands breaks every saved search built on their name. The ID survives.
What is a Facebook Page ID?
A number Meta assigns to a Page when it is created.
It is typically fifteen or sixteen digits, and it is the Page's real identity everywhere in Meta's systems. The vanity handle in the URL - facebook.com/somebrand - is a label sitting on top of it, and labels can be changed by whoever owns the Page.
Three things are easy to confuse:
| Identifier | Looks like | What it identifies |
|---|---|---|
| Page ID | 100064123456789 | The Facebook Page |
| Page handle | /somebrand | A changeable alias for the Page |
| Ad Account ID | act_123456789 | The advertiser's ad account, not public |
The Ad Account ID is not exposed publicly, and no legitimate tool will hand you a competitor's. If a service claims to, be sceptical.
Method 1: the Page Transparency section
The official route, and the one that always works.
- Open the Page on desktop.
- Click About in the left navigation.
- Scroll to Page transparency and open it.
- The Page ID is listed alongside the creation date, country, and whether the Page is currently running ads.
This section is genuinely useful beyond the ID. It tells you when the Page was created - a Page opened six weeks ago running heavy spend is a very different competitor from a ten-year-old brand - and it confirms whether ads are running before you go looking for them.
Method 2: the Ad Library URL
If the advertiser is running ads, the Ad Library hands you the ID.
Go to facebook.com/ads/library, search the brand name, and click through to their ads. The address bar will contain a view_all_page_id= parameter. The number after it is the Page ID.
This is the most convenient method when you are already doing ad research, because you were going to open the library anyway. It also confirms the ID belongs to the Page actually running the ads, which matters for brands with several regional Pages.
Method 3: the page source
Reliable when the About tab is unhelpful, which happens on some older or converted Pages.
Open the Page, view the page source, and search for "pageID" or fb://page/. The numeric value next to it is the ID. On a mobile browser you can usually get the same result by viewing the desktop version first.
This is a fallback rather than a first choice. It works, but Meta's markup changes periodically, so the exact key you search for may shift.
Method 4: the mobile app share link
Quick when you are on a phone.
Open the Page in the Facebook app, tap the share icon, and copy the link. For Pages without a vanity handle, the copied URL contains the numeric ID directly in the form facebook.com/profile.php?id= followed by the number.
For Pages that do have a handle, this returns the handle instead, so it only helps some of the time.
What do you do with the Page ID once you have it?
Three things that make competitor research durable.
1. Pin the exact advertiser. Searching "Nike" in the Ad Library returns fan pages, regional accounts and unrelated brands. A direct URL built on the ID opens exactly one advertiser's ads, every time. This is the backbone of finding a specific brand's Facebook ads.
2. Build a watchlist that does not rot. Save each competitor as an ID rather than a name, and a rebrand stops breaking your tracking. See building a competitor ad watchlist for the structure.
3. Track changes over time. With a stable identifier you can compare the same advertiser's ad count month to month and see when they scaled or pulled back - the core of tracking competitor ad changes.
How do you check you have the right Page?
Confirm three things before you commit an ID to a tracking sheet.
The creation date. Page transparency shows it. If the brand has traded for a decade but the Page was made last year, you are probably looking at a regional or secondary Page.
The country the Page is managed from. A Page for a UK retailer managed from three countries you do not expect is worth a second look before you treat it as the main account.
Whether ads are actually running. The same section says so. There is no point building a watchlist entry around a Page that has not advertised in a year.
Record the ID next to the brand name and the date you checked it. When a competitor rebrands - and in fast-moving categories they do - the sheet still resolves to the right advertiser and you can see at a glance when the name last matched.
How do you collect an advertiser's ads once you have their ID?
Open their Ad Library page and save what is running.
The Ad Library has no download button and no permanent saving - when an advertiser pauses an ad, it disappears from the library and from any note you made that linked to it. Anything you want to keep has to be saved locally.
Our free Meta Ad Library downloader adds a download button to every ad and a bulk mode that scrolls a whole advertiser's results into one ZIP - videos in original HD, images, and full carousels - with a searchable index and a CSV of every ad. Files are named by advertiser and date, so an ID-based folder structure stays tidy across months of tracking.
Copy the angles you find, not the assets. Reusing another brand's creative commercially is a separate question, and this is not legal advice.
FAQ
Where is the Page ID on a Facebook Page?
Under About, then Page transparency. The section lists the Page ID along with the creation date, the countries the Page is managed from, and whether it is currently running ads.
Is the Facebook Page ID the same as the Ad Account ID?
No. The Page ID identifies the public Page and is visible to anyone. The Ad Account ID identifies the advertising account behind it, is not public, and cannot be looked up from outside.
Can a Facebook Page ID change?
No. The ID is assigned at creation and stays fixed for the life of the Page. The name, handle, profile image and category can all change around it, which is exactly why the ID is the safer thing to track.
How do I find the Page ID from the Ad Library?
Search the brand, open their ads, and read the view_all_page_id= value in the URL. That number is the Page ID for the advertiser whose ads you are looking at.
Why does one brand have several Page IDs?
Large advertisers commonly run separate Pages per country, language or product line, each with its own ID. If you are only tracking one, you may be watching a small share of their actual ad activity.
Can I find a Page ID for a Page that is not running ads?
Yes. The Page transparency method works regardless of ad activity. The Ad Library method does not, because a Page with no active ads has no advertiser view to open.
