How to find your Meta Business ID (Facebook)

The Meta Business ID is the unique 16-digit number identifying a business portfolio. You’ll need to know your Meta business ID to add an agency, freelancer, or collaborator as a Partner to your Business Manager.

Your business manager ID can be found in Meta Business Suite or Meta Business Manager similarly:

1. Go to Meta Business Suite’s Settings.
2. Click ‘Business portfolio info’ on the left.
3. Copy the business ID number under the portfolio name.

Note: A Meta business ID is also known as a business portfolio ID or Partner ID. However, it differs from a Facebook Page ID and a Facebook Ad account ID.
