Quoting previous poster: "Do I have to call?"

For what it's worth, I believe having the KTN in your reservation is only helpful to get TSA Pre at your departure airport in the US. If you are enrolled in Global Entry, you should have access to use it on arrival regardless of whether the KTN was in your reservation.
