How to find your Meta pixel (dataset) ID

In Meta Events Manager, open Data Sources, select your dataset (the pixel), and open its Settings tab: Meta says it shows the ID and the owner of your data. The same ID is written twice in the pixel's base code on your website. If your pixel was linked to a dataset, for example when Meta converted it, the dataset ID and the pixel ID are the same number.

Find it in Events Manager

1. Go to Meta Events Manager.
2. Click Data Sources in the menu on the left.
3. Select your dataset.
4. Open the Settings tab. The ID and the owner of the data are shown there.

If you have several datasets, check the owner on the same tab. It tells you which business portfolio the dataset belongs to, which matters before you share it.

Find it in your website's pixel code

Meta's developer guide says the pixel's base code "contains your Pixel's ID in two places":

• in the line fbq('init', '...'), where the ID replaces the dots
• in the address of the small image inside the noscript part, after tr?id=

Meta recommends adding the base code between the <head> tags of every page you track, so the ID shows up in your page's source. If the pixel was installed through a tag manager or a platform's partner integration, look for it there instead.

Pixel ID or dataset ID?

Meta is merging website, app, offline and messaging events into one view in Events Manager, called a dataset. Agencies and developers may use either word.

• The same number: Meta says your dataset ID "will be the same as your existing pixel ID if an existing pixel is linked to your dataset", for example when your pixel was automatically converted to a dataset.
• A new number: a dataset gets a new ID when no existing pixel is linked to it, for example one created to connect offline events.

Meta says you can use the dataset ID like a pixel ID, for example to set up the Meta Pixel or the Conversions API. So if your developer asks for the pixel ID and you only see a dataset, send the dataset's ID.

Who owns it

The Settings tab shows the owner. Check it before anything else. Meta says "you can't delete a dataset or transfer it to another business portfolio", so a dataset an agency created in its own portfolio stays there. If the owner is your agency, see how to get your Meta assets out of an agency's business portfolio.

What to send your agency instead

An agency that runs your ads needs the dataset shared with its business portfolio, not the ID in an email. Someone with full control of your business portfolio shares it under Settings > Data sources > Datasets > Assign partners, using the agency's business portfolio ID. The first time you share with a business, Meta asks you to declare the business relationship and reaffirm its business tools terms, and the agency has to agree to the request. The full steps are in how to share a Meta pixel (dataset) with an agency.

The access token is something else

If you or a developer set up the Conversions API, you will also see an access token. It is not the ID. Meta's developer guide says it is generated in Events Manager, on the pixel's Settings tab under Generate access token, is passed with every API call, and that the link is only shown to people with developer privileges for the business. Our advice: treat it like a password, and give it only to the person who sets up the Conversions API. An agency that only runs your ads needs the dataset shared, not the token.
