If you plan on applying for a Colorado elk license on April 2, be aware:
A qualifying hunting license, valid between April 1, 2019 and March 31, 2020, must be purchased in order to apply for any 2019 big game license. A qualifying license includes: 1) an annual resident or nonresident small game hunting licenses; 2) an annual resident or nonresident spring turkey license; or 3) resident small game/fishing combination license (only available to residents).
Qualifying licenses for the 2019 big game drawing will be available for purchase on March 1, 2019.
Application for residents is now $7 and Small Game is $24
Application fee for NR is now $9. Small Game is $80
Resident for Turkey is $29,75 for Springs .Since the deadline to apply for Spring Turkey is Feb 1, I think, If you draw that would be a qualifying license.If you don't draw,you must buy the small game license
So make sure you buy these before you apply.
I did not see any such requirements for OTC licenses if they are purchased online or at a vendor.
