About US Zip Codes
USA is a large country with 50 states which are divided in counties, parishes or boroughs depending on the state. Louisiana has parishes and Alaska has boroughs instead of counties. The total number of counties/parishes/boroughs is 3,077.
In 1963 USPS (United States Postal Services) started a postal code system known as ZIP code to fasten and simplify the process of delivery of mails.
ZIP stands for Zone Improvement Plan and our Zipcode finder helps you to find the Zipcode of a particular place by selecting the State, County and the place. You can also find the place corresponding to a particular postcode with the help of this utility.
