When looking for frequency information in the Radio Reference database, do yourself a favor and check the wiki for that database page as well. The wiki contains frequencies that are usually licensed but their actual usage (including PL/DPL/NAC/Color Code/RAN information) has not yet been confirmed. For example, every week I take newly licensed frequency information from the Radio Grants Pages for the Midwest and add it to the proper wiki pages. I'll then add a clickable link to that wiki entry under the corresponding database listing for that licensee. If you don't check the wiki, you might be missing out on activity for that licensee.
If you are able to confirm usage of frequencies listed in the wiki, PLEASE submit the information to the database. Your fellow database users (and database admins) certainly would appreciate it!
