Find your customer ID
Your customer ID is a unique number used to identify your AdWords account. You can use this number to connect your account with other Google products, such as Google Analytics or Google Places. You'll also need to have it handy when you speak with Google AdWords customer service representatives. Just keep in mind that newly registered customer IDs take a few minutes to register on our system
We recommend you only share your ID with people you trust because anyone who has it can use it to access your AdWords information.
How to find your ID
After you sign in to your account, your customer ID will be at the top corner of any AdWords page, near your email address.
