To link an existing AdWords account or another manager account to your manager account:

1. Obtain the AdWords Customer ID number (which appears in the top corner of AdWords account).
2. Sign in to your manager account.
3. Click the Accounts tab.
4. Click the Performance sub-tab.
5. Click the + Account button.
6. Choose "Link existing accounts."
7. Once you’ve reviewed the terms for linking accounts, enter the AdWords account's Customer ID number in the client accounts field. To link multiple accounts at once, enter one Customer ID per line.
8. Click Continue, then Submit.

When you click Submit, users with access to the AdWords account you sent a link request to will receive account alerts and emails inviting them to link to your account.

Any user with administrative access on the invited account or on a linked manager account with administrative ownership can accept your invitation by clicking the gear icon , then selecting Account settings from the drop-down menu. Then, they’ll select Account access from the side navigation and click Accept invitation.

During this process, you'll see a pending notification for the (soon-to-be) managed account in your manager account's "Pending invitations," which can be accessed from the side navigation. Once the invited account accepts your invitation, you'll receive an email confirmation and the account will be automatically linked to your manager account.
