A Brief History of US Postcodes

The ZIP code system was first introduced in 1963 by the United States Postal Service (USPS) to improve the efficiency of mail delivery. The term "ZIP" is an acronym for "Zone Improvement Plan," which was designed to divide the country into specific geographic areas for mail sorting and delivery. Over the years, the system has undergone several changes, including the introduction of ZIP+4 codes in 1983, which added an additional four digits to the original five-digit code.

A standard US postcode consists of five digits, with each digit representing a specific geographic area. The first digit represents a group of states, the second and third digits represent a regional post office, and the fourth and fifth digits represent a local post office or zone. For example, the postcode 10021 represents the area of Manhattan, New York City.

ZIP+4 Codes: What's the Difference?

ZIP+4 codes, also known as extended ZIP codes, add an additional four digits to the original five-digit code. These extra digits represent a specific segment of the population, such as a group of apartments or a business. ZIP+4 codes are used to further refine mail delivery and are often required for bulk mailings and commercial shipping.
