How to Find Your Google Ads Customer ID Number (And Share It With an Agency in 60 Seconds)

TL;DR: Your Google Ads customer ID is a 10-digit number sitting in the top-right corner of your Google Ads dashboard. Log in with the email you used to create the account, copy that number, and send it to your agency. The whole thing takes about 60 seconds. If you have multiple accounts linked to one email, make sure you select the right one before sharing.

When we onboard a new client at Creekside Marketing, one of the first things we ask for is the Google Ads customer ID. Nine times out of ten, that request causes a small panic. People start digging through settings, forwarding us login credentials they should not share, or asking if we can just “look it up.” You do not need to do any of that. Finding and sharing your Google Ads customer ID takes less than a minute. This post walks through exactly how to find your Google Ads customer ID number, the same steps Peterson covers in the Creekside Marketing YouTube walkthrough on account access.

Where Is My Google Ads Customer ID?

Your Google Ads customer ID is displayed in the top-right corner of your Google Ads dashboard as soon as you log in. It is a 10-digit number. You do not need to open any settings or menus, it is right there on screen the moment you are logged in. Log in using the email address you originally used to create the Google Ads account. Once you are in, look to the top-right corner of the page. That number is your customer ID. Copy it and send it to whoever needs it.

That is the shortest version. The rest of this post covers the alternate method, the multiple-account situation, and what the agency actually does with that number once you hand it over.

Step-by-Step: How to Find Your Google Ads Customer ID

Here are the two methods Peterson covers in the Creekside Marketing YouTube walkthrough on finding your Google Ads customer ID, in order of speed.

Method 1: Top-right corner (fastest)

Go to ads.google.com and log in.
Use the email address that was used to create the Google Ads account. Not a team member’s email, not a general company address, the specific one tied to account creation.
Once you are logged in, look at the top-right corner of the screen.
Your customer ID appears there as a 10-digit number.
Copy it and send it to your agency or manager.

That is it. No menus, no digging.

Method 2: Profile settings (alternate)

Log in at ads.google.com with the account-creation email.
Click on your profile icon or name in the top-right area.
Open profile settings.
Your customer ID is listed directly underneath your account information.

Both methods return the same number. Method 1 is just faster.

What If I Have Multiple Google Ads Accounts?

If your email address is linked to more than one Google Ads account, you will see all of them listed when you log in. This is more common than people expect, particularly if a previous agency created a separate account on your behalf, or if you have run ads for more than one business over the years.

Look at the account names and pick the right one before you copy the customer ID. Each account has its own unique 10-digit ID. Send the wrong one and your agency will request access to the wrong account. Fixable, but it costs time. When in doubt, match the account name to the business you are currently running ads for.

If you are not sure which accounts exist under your email, this is a good moment to get clarity on who owns your Google Ads data. We have seen situations where business owners discover old agency-managed accounts they did not know existed, sometimes with old campaigns still burning budget.

Yes. Sharing your customer ID does not give anyone access to your account. It is simply an identifier. Think of it like giving someone your account number so they can send a request, they still cannot do anything until you approve it on your end.

Here is how the process works after you share the number:

Your agency receives the customer ID.
They submit a formal manager access request through Google.
You receive a notification from Google asking you to approve the request.
You log in and accept it.
Access is granted.

Nothing changes in your account until step 4. Your billing, your campaign data, and your account settings all stay under your control. Compare that to handing over your login credentials directly, which is something you should never do. Sharing the customer ID is the correct and safe approach.

Why This Step Trips People Up

Look, the customer ID location is not obvious if you have never looked for it. Most business owners log into Google Ads, see a dashboard full of campaign data, and assume the account ID is buried somewhere deep in settings. It is not. Google puts it right in the corner, but if you have never needed it before, you would not know to look there.

The second stumbling point is the email address. If your business has had multiple people managing Google Ads over the years, the account might have been created under an email address that is not your current one. A former employee, a previous agency, an older address you stopped checking. If you log in and cannot find the account you expect, or the customer ID does not match what your agency is looking for, that is usually the reason.

Here’s the thing about Google Ads account ownership: the email that created the account controls it. If that email belongs to a former vendor, you may need to go through Google’s account recovery process. That is a separate conversation worth having with your current agency before anything else happens.

For more on account ownership patterns and what we find when auditing new client accounts, see our breakdown on Google Ads account access and data ownership.

Once you hand the customer ID to Creekside (or any Google Ads agency), the next step is on our end. We submit a manager access request through Google’s platform. You will receive an email from Google asking you to approve it. Log into Google Ads, go to the access and security section, and accept. Once approved, we have manager-level access and can start working in the account.

From there, we do an initial audit, review campaign structure, check conversion tracking, and put together a plan. You can learn more about how we approach Google Ads campaign management on our Google Ads services page.

Frequently Asked Questions

Where is my Google Ads customer ID number? It is in the top-right corner of your Google Ads dashboard, visible as soon as you log in. It is a 10-digit number. You can also find it under your profile settings, listed directly below your account information.

Do I need admin-level access to find my customer ID? No. The customer ID is visible to anyone logged into the account, regardless of permission level. You do not need admin rights just to read the number.

What if I have multiple Google Ads accounts under one email? You will see all linked accounts listed when you log in. Select the correct account first, then copy the customer ID shown for that specific account. Each account has a different 10-digit ID, so make sure you are sharing the right one.

Is it safe to share my Google Ads customer ID with an agency? Yes. The customer ID is only an identifier. Sharing it does not grant access to your account. The agency still has to send a formal access request through Google, and you have to approve it manually. Nothing changes until you accept.

What if the email tied to my Google Ads account belongs to a former agency or employee? This is a real issue we see on a regular basis. If the account-creation email is no longer accessible to you, you will need to go through Google’s account recovery process or work with your current Google Ads manager to sort out ownership. It is fixable, but it takes more steps than the standard handoff.
