How to Address a Detective?
Detectives (the investigative members of police departments) have ranks just like the military: Sergeant, Lieutenant, Captain …. etc. For example, a detective is formally addressed as ‘Lieutenant (Name)’.
—-Envelope or address block on letter or email:
—-—-(Rank) (Full Name)
—-—-Dear (Rank) (Surname):
—-—-Dear Detective (Surname):
——–—-Which looks like:
——–—-—-Lieutenant William A. Barerra
——–—-—-Sumner County Police Department

In oral conversation detective are formally addressed by rank – but it is common practice to informally address orally as ‘Detective’ or ‘Detective (Name)’.
‘Detective’ is not used socially. See also Police Officers.
