A Meta Pixel ID is the numeric identifier for a website data source in Meta Events Manager. A Pixel ID may look like 123456789012345.
You can find it in Meta Business Suite or Business Manager:
Meta may call the same identifier a Pixel ID or Dataset ID. Shopify, WordPress plugins, Google Tag Manager, and landing-page builders usually ask for this number.
| Item | What to look for |

| Main location | Events Manager |
| Menu | Data Sources or Datasets |
| Identifier | A long numeric ID |
| Alternative label | Dataset ID |
| Used for | Connecting website events to Meta |
| Do not confuse it with | Business ID, ad account ID, or Conversions API access token |
Log in to the Meta account that manages your website tracking. Open Business Suite, select All tools, and choose Events Manager. Some accounts open Events Manager directly from the Business Manager navigation.
Select Data Sources in the left-hand menu. Depending on your Meta account layout, website tracking assets may appear under Datasets or Datasets and pixels.
Choose the data source connected to your website. If several pixels or datasets appear, check the asset name and connected website before copying the ID.
The number may appear in one of these locations:
Copy the complete number without spaces or extra characters.
If the pixel is installed on your website, you can find its ID in the Meta Pixel base code.
fbq('init'.fbq('init', '123456789012345');In this example, 123456789012345 is the Meta Pixel ID.
This method shows the ID currently installed on the page. It may differ from the data source you intended to use, so compare it with the ID in Events Manager.
Meta's Chrome extension, Meta Ads Data Advisor, can detect tracking activity on a webpage. Meta Ads Data Advisor was formerly called Meta Pixel Helper. The extension can show whether pixels and events are firing.
Use it when:
PageView event is firing.The extension shows what is running on the page. You still need to check Events Manager to confirm that the data source belongs to your Meta Business account.
These identifiers and credentials have different uses:
If a platform asks for your Meta Pixel ID, enter the numeric Pixel ID or Dataset ID. Do not enter your Business ID, ad account ID, or access token. Keep Conversions API access tokens private.
You may be using the wrong Meta business portfolio, or your account may not have permission to view the data source. Switch business portfolios and confirm that the pixel or dataset has been shared with you.
Use the ID connected to the website or platform you are configuring. Compare the ID in Events Manager with the ID in your website code or Meta Ads Data Advisor.
Copy only the numeric ID. Remove quotation marks, spaces, and labels such as Pixel ID:. Also check that the platform is asking for a Pixel ID rather than a Business ID or access token.
A correct Pixel ID does not confirm that tracking works. Use Events Manager to test website events, then check the live website with Meta Ads Data Advisor. Browser privacy settings, consent banners, ad blockers, and incorrect code placement can stop events from being received.
The fastest method is Events Manager → Data Sources or Datasets → select your website data source → copy the Pixel ID or Dataset ID.
