Hi,

there's certainly confusion, but that seems to be the case for just about any online system and addresses in Casterton! Indeed I have occasionally been unable to register my address on some websites as they refuse to accept the official format!
All addresses in Casterton, as looked up on the official Royal Mail database, are like this:
<house name> if used
<street number and name> if used
Casterton
Carnforth
Postcode

My intention ultimately is to update OSM with that data for every house in Casterton because it's a total pain for many delivery people and others to find anywhere!

Based on the wiki it looks like I need:
addr:housename (if used)
addr:housenumber (if used)
addr:street (if used)
addr:suberb
addr:city
addr:postcode 

Thanks for pointing me to that wiki page as the ID editor was offering 'addr:place' which I see is incorrect for the UK.

I will attempt to update all the Casterton addresses to that format over the next few days - as long as my edits are not going to get undone by you or someone else!

I'm curious - how come you are checking my edits?
