postcode longitude latitude

[dougal85]

I have a couple of million post codes I'd like to get the longitude and latitude of.

Does anybody know of a service that will allow this? It's basically a one off job I want to do. Google Maps only allow 15,000 per day and still only 50,000 with the enterprise edition.

Yahoo only allow 5000 per day...

I have lon/lat of USA postcodes.. I have run across a few that are missing but it's still around 50,000 of them.

Oops, forgot to make it clear it's UK postcodes i'm interested in.
