These phrases are meant to sound like random letters and numbers, but in certain situations, they can be signs of a serious emergency.
Chances are, you’ve heard of the police code 10-4, which means “affirmative” or an acknowledgment of a message. But if you hear a police officer say 10-33, there’s a police emergency underway.
