How to find your Meta business portfolio ID

Your business portfolio ID is on the Business portfolio info page: open Settings in Meta Business Suite, click Business portfolio info in the left menu, and the number is below the name of your business portfolio. It is the same number older guides call the Business Manager ID. It is not a password: an agency needs it to send you a request or to receive your assets, and on its own it gives no access, because only a person with full control of your business portfolio can share its assets.

Find it on a computer

1. Go to Settings in Meta Business Suite (business.facebook.com, then Settings).
2. Select Business portfolio info in the left menu.
3. Your business portfolio ID is the number below your business portfolio's name.

The same page shows your primary Page, so you can check that you are looking at the right business before you copy the number. If you belong to more than one business portfolio, make sure the name above the ID is the one you mean.

Which ID does the agency want?

Meta and Google use several IDs, and agencies sometimes ask for the wrong one. Here is what each one is for.

• Business portfolio ID. Identifies your whole business portfolio (formerly Business Manager; see the glossary). You need the agency's ID to give it partner access, and the agency needs yours, with your name and email address, to send you a partner request.
• Ad account ID. Identifies one ad account. It shows in the account dropdown at the top of Meta Ads Manager, and in the address bar after act=. An agency uses it to request access to that one ad account.
• Page. When an agency requests a Facebook Page in Meta Business Suite, it finds the Page by its name or URL, so you rarely need a Page ID.
• Dataset ID (pixel ID). Identifies a dataset in Events Manager. If your pixel was linked to the dataset, the dataset ID is the same number as the pixel ID.
• Google Ads customer ID. Not a Meta number at all. In Google Ads, click your profile picture in the top right; the customer ID is listed under your account name.

The ad account ID and the dataset ID each have a guide of their own: the ad account ID and the pixel (dataset) ID.

Which way the ID travels

Who sends which ID depends on who starts.

• You give the agency access. You need the agency's business portfolio ID. The agency finds it in its own Business portfolio info and sends it to you. Then follow how to give an agency partner access.
• The agency asks you for access. The agency needs your business portfolio ID, plus your name and email address, to send a partner request from its own portfolio. You then approve or decline it. See how agencies request access.

Either way works. When you give access yourself, there is no request to wait for: you choose the assets and the access in one go.

You have no business portfolio yet

If you have never used Meta Business Suite, you may not have a business portfolio. You need one to give partner access. To create one on a computer:

1. Go to business.facebook.com and log in.
2. Click the dropdown menu below Home in the top left.
3. Click Create a business portfolio.
4. Enter a name. Meta says it should match your business's public name and cannot contain special characters.
5. If you logged in with a Facebook profile, enter your first and last name and your business email.
6. Click Create or Create portfolio, then confirm the business email address from the message Meta sends.

You get full control of the new business portfolio, and its ID is then on Business portfolio info. One person can create up to two business portfolios.

Is it safe to share?

Yes. The ID tells Meta which business portfolio is meant, the way an account number names a bank account without opening it. Only a person with full control of your business portfolio can share its assets, and a request sent to you can be approved, changed or declined.

Be careful with what arrives after you share it. If you get an invitation to join a business portfolio from a business you do not know, Meta's advice is to decline it. Before you accept a partner request, see how to check that an agency access request is real.

Doing it with an access link

Our access link avoids most of this. The agency connects its business portfolio once by signing in with Facebook, so it never types or sends an ID, and you pick your accounts from lists after you sign in. The exceptions are a Meta ad account and, for now, a dataset: you share those on Meta's own screen, and the box gives you the agency's business ID to paste.
