The number of projects any user or service account can create is limited. If you create a project outside an organization, the quota on your account is used. If you are creating a project within an organization, the quota on both your account and organization are checked, and if either one has quota remaining, the project can be created.
Once your quota is reached, you can request an increase. If you have less than 30 projects remaining in your quota, you can see the number of projects you have remaining in your quota on the New Project page. For more information, see Managing project quotas.
