How to Find Your Facebook Business Manager ID

If you've ever been asked for your Facebook Business Manager ID, you know the quick wave of confusion that follows. Is it your page ID? Is it your ad account ID? Where in the maze of Meta's settings is this one specific number hidden? Knowing how to find your Facebook Business Manager ID (now often called a Meta Business ID) is a small but necessary step for any marketer trying to connect tools or grant access to partners. This guide will show you exactly where to find it and explain why this long string of numbers is so important for managing your brand on Facebook.

What Exactly is a Facebook Business Manager ID?

Your Facebook Business Manager ID is a unique numerical identifier assigned to your Business Manager account, which is the central hub for all your business assets on Meta platforms like Facebook and Instagram. Think of it as the master key to your entire business presence. While you have separate IDs for your Facebook Page, Instagram Profile, or different Ad Accounts, the Business Manager ID sits above them all, tying everything together.

It's a common point of confusion, so let's clear it up. Here’s what it's not:

• Your Facebook Page ID: This number is specific to a single Facebook Page. Followers interact directly with your Page, but the Business Manager is your backstage operational center.
• Your Ad Account ID: Each ad account you create has its own ID. Your Business Manager can hold multiple ad accounts, especially if you manage different clients or product lines.
• Your Personal Profile ID: This is the ID for your personal Facebook profile and should never be used for business purposes.

The Business Manager ID is the container that holds all of these assets. It represents your entire business portfolio, giving you and your partners a secure way to manage permissions, tools, and advertising without handing over personal login details.

Why You Need Your Facebook Business Manager ID

You probably won't need this ID for daily posting, but when you do need it, it’s usually for a high-value task. Retrieving it is essential when you want to level up your marketing operations or get help from others. Here are the most common situations where someone will ask for your Business Manager ID:

• Connecting Third-Party Tools: Most professional social media management tools, analytics platforms, and marketing apps require this ID to securely connect to your business assets via an API. This allows the tool to schedule content, pull performance data, or manage your inbox on your behalf without you having to grant full-blown (and risky) admin access.
• Granting Partner Access: When working with an agency, contractor, or another business, you can grant them "partner" access. Instead of manually adding individuals to pages and ad accounts, you simply provide your Business Manager ID. They can then request access to the specific assets they need, and you can approve or deny permissions from a central dashboard. This is the professional standard for inter-business collaboration on Facebook.
• Troubleshooting with Meta Support: If you ever run into a technical issue with your ads, billing, or pages, a Meta Pro Support agent will almost always ask for your Business Manager ID. This allows them to quickly locate your account in their system and dive into the specific problem without ambiguity.
• Setting Up Advanced Integrations: For developers looking to use the Facebook API for custom applications, such as a custom commerce solution or lead generation form, the Business ID is often needed to authenticate and manage permissions for the app.
• Claiming an App: If your business has a mobile app, you need to register it within Business Manager to run specific types of ad campaigns, like app install ads, and securely manage app data. The process involves associating your App ID with your Business ID.

In short, this ID is your ticket to operating like a professional on Meta's platforms. It's the key to scalability, security, and smooth collaboration.

How to Find Your Facebook Business Manager ID (The Correct Method)

Finding your Business ID is straightforward once you know which menus to click through. Meta periodically updates its interface, but this core pathway has remained consistent. Here’s how to find it step-by-step:

Step 1: Go to Meta Business Suite

Log in to the correct Facebook account and head directly to business.facebook.com. This should take you to the Meta Business Suite dashboard for the business you manage.

Step 2: Navigate to All Tools or Settings

In the left-hand navigation menu, look for the gear icon labeled "Settings" at the bottom. If you can't see this, look for the hamburger menu (three horizontal lines) labeled “All tools.” Click this to expand the full menu of options, and then find and click on "Business Settings" under the 'Manage' section. This is the old "Business Manager" backend where most critical business functions live.

Note: You must be an admin of the Business Manager account to access Business Settings. If you don’t see this option, you may have a different permission level.

Step 3: Click on "Business Info"

Once you’re in Business Settings, you'll see a second navigation menu on the left. This list includes sections like Users, Accounts, and Data Sources. Scroll all the way to the bottom of this list and click on "Business Info".

Step 4: Find and Copy Your ID

Your Facebook Business Manager ID is displayed right at the top of the Business Info page. It will be located directly under your business's legal name, clearly labeled as "Meta Business ID" (or sometimes still referred to as Business Manager ID). It’s a long string of numbers in a light grey box. You can simply click the number to copy it to your clipboard.

And that's it! This number is what you can safely share with trusted partners and software providers.

Quick Tip: Finding the ID in Your Browser's URL

Sometimes, you just need a quick way to grab the ID without clicking through menus. As long as you are on any page within your Business Settings, you can often find the ID right in your browser's URL address bar.

Look at the URL. It will look something like this:

https://business.facebook.com/settings/info?business_id=123456789012345

The number that follows business_id= is your Business Manager ID. You can copy it directly from there. While this method is fast, the official method of navigating to "Business Info" is always the most reliable way to confirm you have the right number, as URLs can sometimes change.

Common Problems and Troubleshooting

Things don't always go as planned in the Meta universe. Here are a few common issues that might pop up and how to solve them.

"I Can't Find 'Business Settings'."

This is the most frequent issue people face, and it usually comes down to one of two things:

• Permission Levels: You need to be an Admin on the Business Manager account to see and access the full "Business Settings" area. If you only have "Employee" access or have been assigned a specific role on a Page or Ad Account, you won't have permission to view this core information. Check with your business's primary owner or another admin to get your permissions upgraded.
• Page vs. Business Account: You might be managing a Facebook Page directly through its native settings, not through a Business Manager. If you've never formally created a Business Manager (now Meta Business Account), you won't have one to find the ID for. You can set one up at business.facebook.com/overview. Setting up a formal Business Account is highly recommended for any business, no matter the size.

"Is This the Same as My Ad Account ID?"

No, and mixing them up will cause any tool or integration to fail. Your Ad Account ID is found in a different place.

To find your Ad Account ID:

1. Go to Business Settings >, Accounts >, Ad Accounts.
2. You'll see a list of all ad accounts in your Business Manager.
3. The unique Ad Account ID will be displayed directly below each ad account's name.

Always double-check which ID you're being asked for. If you're connecting a social scheduling tool, you likely need your Business ID. If you're discussing a specific campaign's performance with an ads specialist, they'll want your Ad Account ID.

"I Manage Multiple Businesses...Which ID Is Which?"

If you're a social media manager or agency running multiple business accounts, make sure you're in the right one before grabbing the ID. In the Meta Business Suite or Business Settings, there is a dropdown menu in the top or left navigation panel that shows the business you are currently viewing. Click it to see a list of all Business Managers you have access to. Select the correct business from the list and then follow the steps above to get the right ID.
