Merge Two Facebook Ad Accounts: Best Workarounds and Management Tips

Managing multiple Facebook ad accounts can easily turn into a fragmented and time-consuming process — especially for brands scaling into new markets or agencies working with many clients. It’s completely reasonable to wish for a single “Merge” button that combines everything: campaigns, billing, audiences, reporting, and pixels. But the technical reality is different: Meta does not allow merging two Facebook ad accounts into one.

Each ad account carries its own identity — a permanent account ID, billing history, optimization learnings, and permission structure. Combining two IDs would cause a conflict of ownership, financial records, attribution, and compliance. That’s why Meta has stated repeatedly across the Help Center and support channels that merging is not supported and will not be supported in the future.

So, what can advertisers do instead?

The best alternative is account consolidation without merging, achieved through Meta Business Manager. You can bring multiple accounts into one Business Manager, giving your team a unified environment to manage access, View aggregated performance, and centralize billing.

Beyond permissions, the most impactful workaround is data consolidation. By sharing your Pixel, Aggregated Events, Lookalike and Custom Audiences, and Conversions API connections across accounts, you unify optimization signals. This allows Meta’s machine learning to improve performance even if the structure remains separate.

Another smart workaround: campaign consolidation. Identify winning campaigns from multiple accounts and recreate them inside one primary account — improving learning stability and reducing budget fragmentation. Keeping fewer accounts active also eliminates the risk of duplicate audiences, self-competition, and reporting complexity.

Most operational challenges with multiple accounts fall into three buckets:

1️⃣ Ownership Confusion – When accounts belong to different Business Managers

2️⃣ Fragmented Data Tracking – When multiple pixels produce incomplete reporting

3️⃣ Security Risks – When ex-staff or old partners still retain admin access

To avoid these problems, build a policy-driven structure: a single Business Manager per organization, strict role assignment, regular access audits, and unified account policies. For agencies, assign Partner Access instead of giving external users full admin rights.

Even though merging isn’t technically possible, advertisers can still reach the same outcome by shifting toward a centralized ecosystem: streamlined management, unified signals, and consistent scalability.
