What's the policy behind ranges? Some ranges only have the lower range, they seem to be address like (ie address 11A-11H, will have a range_low of 11, but no range_high). Some have Letter suffix ranges ( ie '13A-13E'), and both a declared in the range columns. These seems to be subdivisions. Is there any definitive documentation?

I've asked one of our Addressing Analysts and this is his answer:
The range_low and range_high only include the base numbers, not the alphas or flat numbers.
The range_high is only populated if the house_number field contains a range of base numbers, otherwise it should be null.
However, the house_number shows everything, so it could be 12A-12C, 1/12-3/12, 1A/12-1C/12 etc, but in these examples the range_low would be 12 and the range_high would be null.
If the house_number was 12-14 then the range_low would be 12 and the range_high would be 14.
I hope this helps.
