Find your Customer ID, send it to your agency, then accept their manager link request in Access and security.
Most agencies manage Google Ads through a manager account (sometimes called an MCC). Linking your account to theirs gives them access to build and optimize campaigns, while you keep ownership of the account, the billing, and the data. The whole process takes a few minutes.
Your Customer ID is the 10-digit number (for example, 123-456-7890) at the top right of your Google Ads dashboard, next to your account name.
Email the Customer ID to your agency. They'll use it to send a link request from their manager account. Your Customer ID alone doesn't give anyone access, so it's safe to share.
Google emails your account's admins when the request comes in. You can click Accept request in that email, or do it inside Google Ads:
Only users with Admin access can accept link requests.
If your agency asks for direct user access instead of a manager link:
What if I don't have a Google Ads account?

Where can I read Google's instructions?
