MCC Account Relinking Process

Overview

When a client's Google Ads account becomes inaccessible — due to a prior manager account being reclaimed, a business relationship ending, or account restructuring — the account must be manually relinked to the active manager account (MCC). This procedure documents the steps to restore access without requiring the client to grant fresh admin credentials.

This situation arose in February 2026 when multiple client accounts previously managed under the "Get Found Madison" MCC (ID prefix: 589...) became inaccessible, suspected to have been reclaimed by a former agency owner. The resolution was to relink each affected account to the Asymmetric MCC (ID prefix: 810...).

When to Use This Process

• A manager account (MCC) you previously used to access client accounts is no longer visible or accessible
• Client accounts show up in your credentials sheet but are not reachable through your current MCC
• A prior agency or manager may have reclaimed a parent MCC account
• You need to migrate client accounts from one MCC to another

Prerequisites

• The client's Google Ads account ID (numeric, e.g. 123-456-7890)
• Access to the Asymmetric team MCC account (not a personal Asymmetric email login — see note below)
• A contact at the client who can accept the manager link request

Important: Relinking requests must be sent from the team MCC account, not from a personal Asymmetric email address. Requests sent from personal accounts will fail silently or not be accepted correctly.

Finding Affected Account IDs

Client Google Ads account IDs and their associated MCC accounts are tracked in the internal credentials spreadsheet:

• Column P — Client Google Ads account ID
• Column Q — MCC account currently linked (manager account ID)

Any account in Column Q with an ID starting with 589 is linked to the old Get Found Madison MCC and needs to be relinked. Any account starting with 810 is already under the Asymmetric MCC and does not need action.

⚠️ This spreadsheet contains credentials for all client accounts. Do not share it externally or modify it without authorization.

Relinking Procedure

1. Log in to the Asymmetric team Google Ads account (not your personal Asymmetric email).

2. Navigate to the MCC account view. Confirm you are in the top-level manager account — you'll know you're in the right place because the left sidebar will show "Accounts".

3. Go to Sub-accounts in the left navigation.

4. Click "Link existing account" (not "Create new account").

5. Paste the client's Google Ads account ID from the credentials spreadsheet.

6. Click "Send Request." The client (or their Google Ads admin contact) will receive an email asking them to accept the manager link.

7. Follow up with the client contact to accept the request. The request will appear in their Google Ads account under Settings → Account Access. Acceptance typically takes a few minutes once they log in.

8. Verify access by confirming the account appears under the Asymmetric MCC sub-accounts list.

9. Update the credentials spreadsheet — change Column Q for that client from the old MCC ID to the Asymmetric MCC ID (810...).

Accounts Affected (February 2026 Incident)

The following accounts were identified as needing relinking from the 589... MCC to the 810... MCC:

Note: King Company was excluded — Asymmetric manages their website only, not their ads.

Troubleshooting

The client hasn't accepted the request after several days.
Send a direct email to the client contact explaining they need to log into Google Ads and accept a manager access request. Include the approximate date the request was sent so they can find it.

The send request button is greyed out or fails.
Confirm you are logged into the team MCC account, not a personal email. Personal Asymmetric email logins cannot successfully send sub-account link requests.

You don't have the client's account ID.
Check the credentials spreadsheet (Columns P/Q). If the ID is missing, check historical emails — account IDs are often included in Google Ads notification emails sent when the account was originally linked.

Google Support route.
If the account ID is unknown and no historical emails exist, open a case with Google Ads support referencing the account name and business. Note: Google support response times can be slow (days to weeks).
