ZIP Code Maps

Here is a basic ZIP Code map showing the different state ZIP codes and ranges. I've been looking for a good ZIP Code map for a while now and the above is pretty straightforward. While this doesn't give you much in terms of detail, it is a good overview.

Next is a great link to a ZIP code distribution map which is an interactive Java applet where you can see the exact location of each ZIP Code range or down to the specific zip code itself.

Area Code Maps

I have recently been looking into how to track phone numbers and the constantly changing area codes. A great resource was found called NANPA. Still not sure what this stands for but these guys are the ones who set the phone numbers, so I would say it is a reliable source. This is the best area code map site I have seen as well.
