The Google Ads Customer ID is a three-part number that is assigned to each Google Ads account.
If you are a client account manager, you will need to enter the Customer ID of the client of interest when prompted to do so during the import process. You can find the Customer ID on the top-lefthand corner of your account underneath the client account name. Keep in mind that your Manager ID is different from the client’s Customer ID.
Your customer ID is a unique number used to identify your Google Ads account. You can also use this number to connect your account with other Google products, such as Google Analytics or Google My Business. This article will show you how to locate your customer ID.
