A '''letter box''', '''letterbox''', '''letter plate''', '''letter hole''', '''mail slot''' or '''mailbox''' is a receptacle for receiving incoming [[mail]] at a private residence or business. For outgoing mail, [[post box]]es are often used for depositing the mail for collection, although some letter boxes are also capable of holding outgoing mail for a [[mail carrier|carrier]] to pick up. Letterboxes or mailboxes use the following primary designs:

* A slot in a [[wall]] or [[door]] through which mail is delivered (through-door delivery)
* A [[box]] attached directly to the building (direct-to-door delivery)
* A box mounted at or near the street ([[curb (road)|curbside]] delivery)
* A centralised mail delivery station consisting of individual mailboxes for an entire building also known as a "flock" throughout the South Island of [[New Zealand]] and parts of America.
* A centralised mail delivery station consisting of individual mailboxes for multiple recipients at multiple addresses in a particular neighborhood or community
