Managing Facebook ads efficiently starts with understanding one key detail: your Facebook Ad Account ID. This unique identifier, usually 13–16 digits (e.g., act_123456789012345), is more than just a number—it’s the backbone of your advertising operations.

Your Ad Account ID ensures proper tracking of campaigns, billing, and reporting. Meta’s support team uses it as the primary reference when troubleshooting issues like delivery problems or billing errors. It’s also essential for integrating with third-party tools such as CRMs and analytics dashboards, enabling seamless synchronization of campaign data across multiple platforms.

For teams and agencies, the Ad Account ID provides a secure way to share access without revealing login credentials. Instead of handing over passwords, you can grant access via Business Manager, assigning roles like Admin, Advertiser, or Analyst. This keeps accounts secure while allowing collaborative campaign management.

Finding your Ad Account ID is simple. In Ads Manager, it appears in the top-left corner of your dashboard or in the URL after “act=”. In Business Manager, navigate to “Business Settings → Ad Accounts” to see all linked accounts and their IDs. For users managing multiple accounts, IDs also display in the account switcher menu, helping you distinguish between clients or business units.

Best practices include limiting access permissions, auditing accounts quarterly, and using Business IDs when working with agencies. These steps maintain security and prevent unauthorized access.

Common issues like integration errors or confusion between accounts often come down to misusing IDs. Double-checking the correct ID before granting access or setting up tools helps avoid mistakes.

In short, your Ad Account ID is the foundation for smooth ad management. By knowing where to find it, how to use it, and how to share it securely, you keep campaigns running efficiently while safeguarding your advertising assets.
