Where can invited users see the contacts I share with them?

Users who receive access to your shared contacts can find them on every device and in many applications. These are, for example:

1. Google Contacts: they will see the shared labels containing the shared contacts. The shared labels are marked “(Shared).”
2. Google Mail
3. All Google apps
4. Mobile phone books
5. Every application connected to Google Contacts. 

Keep in mind, however, that if the app hasn’t been installed across the entire domain by the admin, the user will need to grant the necessary permissions. This can be done either by following the link provided in the email invitation or by opening the app, which will prompt the user to grant permissions automatically.
