A Code 47 was, in both Federation Starfleet and Lyran Starfleet, a secure communications channel which deleted all records after the closure of the channel. Opening the channel required a voiceprint and was only feasible if one was ranked captain or above. (Star Trek: Lambda Paz: "Divided Loyalties")
A Code 47 was used by Goursat to contact Brianna Reiss regarding evidence of Title XI violations committed by Lyran duke Roshak. (Star Trek: The Stoneship Files: "Post-Apocalyptic Education")
