The Google Merchant Center Help document was recently updated with new information. GMC for agencies can now link up to 1,000 client accounts.
Previously, there was no clear information available about account linking limits. Now Google has spelled it out directly.
Google wrote: “As an agency admin, you can link up to 1000 client merchant center accounts.”
When was Google Merchant Center for Agencies launched?
Google launched this feature in beta in October 2025, before rolling it out to the US and Canada. It then expanded globally in May 2026.
This update gives agencies a clear number to work with when managing multiple client accounts, which is especially useful for larger agencies handling Shopping campaigns across many merchants at once.
