N.B. stands for the Latin words nota bene, which mean note well. In English correspondence, writers place it before an extra detail that requires attention. It does not replace the main message, but it highlights a condition, reminder, or helpful update that belongs with that message.
N.B.: Parking permits are available at the front security desk.
