Anotations

Scope note:

Public or private containers for pickup or delivery of mail. For rented compartments in officially designated post offices, use "post-office boxes." The term formerly referred to boxes in which the mailbags were placed on a mail coach or steamer. In British usage, "mailboxes" typically refers specifically to such containers placed on a pole or post on a person's property, while "letter-boxes" typically refers to the larger boxes located in public places.
