post code - distance between two - software available?
Discussion
Got a client who is building a website, who wants us to look into ingrating a post code search feature, which only displays results of locations which are within a specified distance of the post code being referenced.
Can anyone recommend any companies who provide post codes and the search algorythm? Last I enquired, prices were between 1-2k, per year.

The expensive bit is the cost of the PAF data from the Royal Mail rather then the software itself.
If you don't need it to be too accurate the list available here might do the trick (only works on the first part of the postcode)
Cheers, will have a proper look in a bit. Youre right, the algorithm is a piece of cake to install from what I remember being told, its the data and updates which cost. Thanks again!

I use these guys.

I've not used the distance calculator, but it says on the above page they do it.
They have been dead easy to setup, and seem to do exactly what they say on the tin for what I consider to be a reasonable charge.
Cheers,

The UK postcodes can be bought on the "blackmarket" for an inconsiderable fee (about £120 odd) but beware that the Royal Mail own the rights to lat/long coordinates that translate to the postcodes themselves.
The pays as you go price from the link above seems a cheap option, depending of course on the number of queries it will likely see.

If you convert postcodes into co-ordinates you can do some simple trig to work out distances.
The info is available on the net, and importing the data into a SQL database isn't hard either.
Can help if you need any more info on going down that line.

thats how we do it, we use postcode anywhere on a pay as you go scheme.
It is possible to cache the data....

Pah, and I thought my plan a year or so back was ingenious!
Not telling you were I got my postcodes from...but there's a website on-line that will let you do 200 at a time, converting from postcode to long/lat. Or you can pay to do them in bulk. Doesn't stop you doing multiple passes of 200 though, nor tell you not to.
