What is a US ZIP code?
The United States Postal Service developed zip codes for the United States to help them organize mail and deliver it in a timely and efficient manner. U.S. ZIP codes were introduced in 1963 as the Regional Improvement Program.
Simply put, it is to represent the specific address of the United States by numbers.
A 5-digit zip code is a representation of a set of numbers that the Postal Service is regularly formed to do. The first digit represents the state code, the second and third digits represent the county, and the fourth and fifth digits represent the city code.
