Letters can be manually added but are not considered when a new project is created.
You can decide to:
Allow Duplicate Project Numbers: Select Yes to allow duplicate Project numbers. If set to No each Project must have a unique number.
Allow Editing Project Numbers (Default set to Yes): If changed to No, Users can no longer change a Project's Number once it's saved. They can, however, still edit the number on new Projects.
With the Project Number Builder it is possible to build project numbers with two different formats.
