ZipDecode which I am calling here has Zip Code map is really cool project which allows you have more understanding of how ZIp system works out in us. This can also help you to find the exact city or town location in USA if you have the zip code. Pretty Handy. So lets say I want to know on Zip Code 89511. I will start with 8 then 9 then 5 and so on.
Got the idea ? As you key in the numbers you will understand how many are covered in and so on. So if you want to find out about your Zip code just check out Zip De code
