# How to find your Google Ads manager account (MCC) ID

Agencies usually manage their clients' Google Ads accounts from a **manager account**, often called an MCC. To get
access, you link each client account to it. For that you need your manager account's **customer ID**: ten digits,
written like `123-456-7890`.

## Where it is

1. Sign in to [Google Ads](https://ads.google.com/aw/accounts) with the Google account that manages your manager account.
2. Open the account switcher at the top. Your manager account is marked as a manager account; its ID is shown next to
   its name.
3. Inside the manager account the same ID is at the top right, next to the account name.

Check that it says **manager account**. Client accounts have the same ten-digit format, and sending a client account's
ID is the most common mix-up.

## Why link instead of adding a user

A client can also add your email as a user of their Google Ads account. Linking to your manager account is better for
both sides:

- your whole team gets access through the manager account, without the client adding every person;
- when someone leaves your agency, you remove them in one place;
- the client sees one clear connection to your agency and can end it in one place.

## How the link is made

The manager account sends a link request to the client's account, and an admin of the client's account accepts it
(in Google Ads under **Admin › Access and security › Managers**). Since 2026 Google asks for a **passkey** for this
step; see [Google Ads now needs a passkey](/guides/google-ads-passkey-requirement).

## Frequently asked questions

### Does a manager account cost anything?

No. Creating a Google Ads manager account is free.

### Can a client account be linked to more than one manager account?

Yes, a client account can be linked to several manager accounts, for example its agency and an in-house team.

## With Agency Client Onboarding

Enter your manager account ID once under **Recipients**. If you connect Google Ads there as well, Google confirms the
account and the link request is sent for you when a client picks their account.
