Rule 1 - No building name, number or sub building name No premise elements detected (typically organisation name)
Rule 2 - Building number only
Rule 3 - Building name only
Check format of Building Name (see note (a) above). If the Exception Rule applies, the Building Name should appear at the beginning of the first Thoroughfare line, or the first Locality line if there is no Thoroughfare information.
When a building has a name AND a number range, both must be held in the Building Name field because the Building Number field can only hold numeric characters.
If an address has a building name with text followed by a space and then completed by numerics/numeric ranges with the numeric part an exception (see Note (a) above), the numerics/numeric range are treated as a building number, and the text part is treated as the Building Name and the numerics/numeric range are split off to appear at the beginning of the first Thoroughfare line, or the first Locality line if there is no Thoroughfare.
Rule 4 - Building Name and Number
The Building Name should appear on the line preceding the Thoroughfare and/or Locality information. The Building Number should appear at the beginning of the first Thoroughfare line. If there is no Thoroughfare information then the Building Number should appear at the beginning of the first Locality line.
Rule 5 - Sub Building Name and Building Number

If there is no Thoroughfare information then the Building Number should appear at the beginning of the first Locality line.
Rule 6 - Sub building name and building name
