In this guide, we’ll explain what a Facebook Ad Account ID is, why it’s important, and where to find it within Meta’s Ads Manager and Business Manager interfaces. You’ll also learn best practices for managing your account securely, including how to share access with partners or team members while keeping control of your advertising assets. By the end, you’ll have all the knowledge you need to confidently handle your Facebook Ad Account ID and maintain seamless campaign management.

What Is A Facebook Ad Account ID?

A Facebook Ad Account ID is a unique numerical identifier assigned to your advertising account on the Facebook platform. This ID consists of a series of numbers, typically 13-16 digits long, sometimes preceded by "act_" (e.g., act_123456789012345). The identifier serves as a digital fingerprint for your specific advertising account within Facebook's system.

Each Facebook Ad Account ID maintains complete separation between different advertising accounts operated by the same business or individual. The ID enables Facebook's system to properly attribute all campaigns, ad sets, and individual advertisements to the correct account. This separation ensures accurate tracking of performance metrics, billing information, and spending limits specific to each advertising account.

Facebook automatically generates this identifier when you create a new advertising account through either Business Manager or Ads Manager. The ID remains consistent throughout the lifetime of your account and cannot be changed or customized. This permanence helps maintain continuity in tracking, reporting, and integration with third-party advertising tools.

Why Your Ad Account ID Matters

Your Facebook Ad Account ID functions as the primary reference point for managing all advertising activities on the platform. The ID provides essential access to advertising data when communicating with Facebook's support team about account issues or campaign troubleshooting. Support representatives typically request this identifier first to locate your specific account within their system.

Ad Account IDs enable seamless integration between Facebook's advertising platform and third-party marketing tools. Many analytics platforms, CRM systems, and marketing automation tools require your Ad Account ID to establish connections for data synchronization and campaign management. These integrations allow for more comprehensive tracking and optimization across multiple marketing channels.

For businesses working with external agencies or marketing consultants, the Ad Account ID facilitates secure access delegation. Instead of sharing login credentials, businesses can grant specific levels of access to their advertising account using this identifier. This approach maintains account security while enabling collaborative campaign management.

Where To Find Your Ad Account ID

Facebook displays your Ad Account ID in several locations throughout the Ads Manager interface. The most accessible location is in the URL of your browser when viewing your Ads Manager dashboard. Look for the sequence that appears after "act=" in the address bar (e.g., https://business.facebook.com/adsmanager/manage/accounts/act_123456789012345/).

Within the Ads Manager dashboard, locate your Ad Account ID in the top-left corner of the screen. Facebook typically displays this information alongside your account name for easy reference. The identifier appears in a standard format with all numerical digits grouped together.

For users managing multiple advertising accounts, the Ad Account ID appears in the account selection dropdown menu. Click on the account switcher in Ads Manager to view a list of all accessible accounts with their corresponding IDs clearly displayed. This feature helps distinguish between similar account names when working across multiple clients or business units.

Using Facebook Ads Manager

Finding your Facebook Ad Account ID through Ads Manager takes three simple steps. 

1. First, navigate to Facebook Ads Manager and log in with your advertising account credentials.

2. Locate your Ad Account ID in the upper left corner of the page, displayed as a series of numbers (typically 13-16 digits) sometimes preceded by "act_" (e.g., 123456789012345).

For multiple ad accounts access:

2. Each account listing displays its corresponding ID, allowing you to select the specific account you need. 

3. Alternatively, click on "Account Overview" to find a dedicated section showing your AD ACCOUNT ID in a more detailed format.

Through Business Manager

Business Manager provides another method to access your Facebook Ad Account ID. 

1. Visiting Facebook Business Manager and logging into your account. 

2. Business Manager centralizes control of multiple Facebook business assets, including ad accounts, pages, and other marketing tools.

3. From the Business Manager dashboard, click on "Business Manager" in the top left corner

4. Select "Ads Manager" from the dropdown menu. This action takes you to a page displaying all ad accounts associated with your Business Manager.

For security purposes, share your Ad Account ID only when necessary for support requests or when granting access to trusted partners. The ID serves as a crucial reference point when communicating with Facebook's support team and enables secure delegation of account access without sharing login credentials.

How to Use Your Facebook Ad Account ID to Access And Share Facebook Ad Accounts

Facebook Ad Account IDs serve as essential keys for managing access permissions and collaborating with partners on advertising campaigns. These unique identifiers streamline the process of requesting and granting access to ad accounts without sharing sensitive login credentials.

Requesting Access As A Partner

Requesting access to a Facebook Ad Account requires the account's ID and proper navigation through Business Manager settings. To request access:

1. Obtain the Facebook Ad Account ID from the account owner. This ID typically appears as a series of numbers, sometimes preceded by "act" (e.g., act_123456789).

2. Navigate to Business Settings in your Business Manager account at business.facebook.com after logging in.

3. Select "Accounts" and then "Ad Accounts" from the left menu options to view your current ad account connections.

4. Click "Add" and select "Request Access to an Ad Account" from the dropdown menu to initiate the request process.

5. Enter the Ad Account ID provided by the account owner in the designated field.

6. Choose the required permission level based on your role and responsibilities. Options typically include:

• Admin: Complete control over the account

• Advertiser: Create and manage campaigns

• Analyst: View performance data only

7. Submit your request for the account owner to review and approve through their Business Manager notifications.

After submission, the account owner receives a notification to approve or deny your access request. Access permissions activate immediately upon approval, allowing you to begin working on the account based on your assigned role.

Sharing Ad Account With Others

Facebook's Business Manager provides streamlined methods for sharing Ad Account access with team members or external partners. To share your ad account:

1. Access Business Settings by logging into business.facebook.com and clicking the settings icon in the bottom left corner.

2. Navigate to "Accounts" and then "Ad Accounts" from the left sidebar menu.

3. Select the specific ad account you want to share from your list of managed accounts.

4. Choose either "Add People" or "Assign Partners" depending on whether you're sharing with individuals or another business.

5. For individuals: Enter their email address or select from existing Business Manager users. For partners, enter their Business ID number.

6. Assign appropriate permission levels based on their responsibilities:

• Admin: Full control including payment methods and account settings

• Advertiser: Create and manage ad campaigns

• Analyst: View reporting and performance data only

7. Click "Assign" to finalize the permissions and send notifications to the recipients.

Access management requires regular review to maintain security. Implementing a quarterly audit of all users with access to your ad accounts ensures that permissions remain appropriate as team members change roles or leave organizations. This practice prevents unauthorized access to your advertising assets and budget.

When sharing access with external agencies, the partner Business ID method provides greater security than individual email invitations. Using Business IDs ensures that access remains managed at the organization level rather than through individual accounts that might change over time.

Facebook's role-based permissions model helps maintain proper separation of duties, allowing you to grant precisely the level of access each stakeholder needs without exposing sensitive account information unnecessarily.
