title: Google Cloud Platform: project appears in billing reports but doesn't show in the list of projects
body: <p>Our organization uses Google Cloud APIs for integrating Maps and other services in a number of websites.</p>
  <p>We have often used the same API key, without creating a distinct Google Cloud project (and credentials) for each website/project.</p>
  <p>We are trying to better organize our API usage, but we are facing an issue.
  While we can consult the reports of our Billing account and see the quota for the unique API project used for every implementation, <strong>we cannot see and manage this project (it does not appear in the list) even though it seems to belong to the same organization</strong>. <em>(EDIT: I am not sure that the organization id is the same, but the name of the organizazion appears as a prefix to the project name in the billing reports)</em></p>
  <p>This project has been created years ago (and the person that created it appears not to have access to it either), but we need to access it to get a clear understanding of where and how APIs are used.
  The connected APIs are still in use and working, so we assume the project exists.</p>
  <p>Can someone point out the possible reasons why a project is not shown even though it belongs to an organization for which we have access as administrators?</p>
  <p>Thank you in advance</p>
