Do mailboxes have to be in numerical order?
In respect to this, do you have to have numbers on your mailbox?
The box or house number on a mailbox must be represented in numbers that are at least 1 inch tall. Mailboxes must be placed 6 to 8 inches away from the curb; the incoming mail slot or door must be 41 to 45 inches from the ground.
Besides, do you have to put your name on your mailbox?
The general rule for carriers: "When in doubt, deliver." There is no need for any names at all on your mailbox, and there are some good reasons not to have your name publicly posted with your address (potential identity theft, desire for privacy, even witness protection program).
The Postal Service permits moving a mailbox, but it must be placed in a location that is readily accessible by a mail carrier. For example, roadside mailboxes must in a location where mail carriers can place mail from their delivery vehicles.
