Values in use in United Kingdom
|pillar|| A freestanding box, taking the form of a column. Usually cylindrical in shape in the UK, but rectangular forms can also be seen.
|lamp|| A self-contained box, smaller than a pillar box, and designed to be mounted above ground level. Usually attached to a pole, slim pedestal, lamp post, or telegraph pole in the UK, but can be mounted on (or very rarely within) a wall.
|wall|| A box designed to be set into a wall. Can be found mounted in walls, walls of buildings, and also in free-standing brick pillars.
|meter|| A special type of post box that is designed to only accept pre-paid business mail (known as "meter mail" in the UK). The special adaptations may include a larger aperture and/or mechanisms to prevent unauthorised persons from using the box.
While this value is about the physical appearance/design of the box rather than the mail types accepted, it will normally only be used on boxes that only accept this special type of mail. It would be unlikely to find one of these specially adapted meter mail boxes being used for ordinary mail. However, it may be more common for ordinary boxes to accept special types of mail.
In the UK these "meter" boxes are normally larger square pillar boxes with a larger mechanical aperture that is locked outside specified opening hours.
Since this classification is distinct from, and in some sense orthogonal to, the other post_box:type=* values, it has been suggested that a different key should be used for this attribute, leaving post_box:type=* to tag the box with the best fit from pillar, lamp, and wall.
