OpenStreetMap
The postcodes in my local area are a bit of a hash... but correcting them is tricky. I realise there's an entire discussion about acquiring postcodes, but when you've lived most places in an area that's not so much of a problem! How does one go through making it all right though?

Ordnance Survey have just released "Code-Point Open", so it's shortly going to just be a matter of importing that (if people decide it's something that should live _inside_ the osm db itself).

importing the OS data is pointless -- they just give the location of the centre of each postcode, and it's trivial to merge it.
In terms of finding them etc, best thing is to apply them to the buildings and addresses they actually are for. That's the most useful in the long term. To look for them in an area already mapped use JOSM and search for addr:postcode. You'll possibly also find prefixes on streets with postal_code -- but these are less useful now.

Well, that's given me something to go on anyway - thanks.
Next thing to fix will be the area names - I'm wondering if there's a simple way of setting up a boundary. At the mo it seems that everything in Derby is in Peartree...
