I have dealt with a number of customers that call their request by type ID number rather than using the label itself.  To allow the request id number to be displayed when you are creating a new request, have the Resource go to the Preferences / Workflow / Workflow: Settings and check the box.  This will turn on the numbering option in the zNew Request screen.

This functionality like its other option on this screen, Workflow Pop-Up is set by User, not available under the Corporate (Settings) tab.
