Need to find a postcode from somewhere around the world? I was asked this question the other day and so I thought I'd share a nice resource that I've found. It's called - surprise surprise, Postal Codes. Very simple to use - just find the country you're interested in and type in the location that you need a code for. You then get a really nice long and comprehensive listing of post codes and their areas. It also works the other way around - you can type in a code that you know, and it will show you where it comes from, plus link you into the Google map page for the area.
Nice, quick, simple and free.
