Bainyzip.com – ZIP Code Lookup
The ZIP postal code system was implemented by the United States Postal Service in the year 1943, and the acronym stands for “Zone Improvement Plan”. If you ever come across a ZIP code and want to know more about it, then a visit to the BrainyZip website is the order of the day.
The site has a search tool that lets you find information such as State, County, latitude, longitude, and Post Office Name just by keying in the relevant code. On the other hand, the available ZIP codes are alphabetically presented in the main page, and visitors can browse through them in order to find the one they are looking for. This list contains the first two digits of each code (every ZIP code is made up of five characters). A reverse search can likewise be performed, this time browsing by State in order to find the correlative ZIP code. Lastly, it is important to mention that when it comes to the most populated ZIP codes the BrainyZip website provides demographic, social, economic and housing data and information.
