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:
- Go to Meta Business Suite’s Settings.
- Click ‘Business portfolio info’ on the left.
- Copy the business ID number under the portfolio name.
Note: A business ID is different from a Facebook Page ID.
