History of Zip Codes in Colorado

The United States Postal Service (USPS) introduced the zip code system in 1963 to streamline mail sorting and delivery. Colorado, with its vast territory and growing population, was one of the first states to adopt the new system. Initially, the state was divided into several large zip code areas, but as the population grew, the USPS expanded and refined the system to include more specific and localized zip codes.
How Zip Codes Work in Colorado

Colorado's zip code system is designed to facilitate efficient mail sorting and delivery. The state is divided into several sections, each with its unique zip code prefix. The prefixes are assigned based on geographic location, with the first digit representing the region, the second and third digits representing the sectional center facility (SCF), and the final two digits representing the specific post office or delivery area.
Zip Code Formats
Colorado zip codes follow the standard USPS format, consisting of five digits. However, some areas may use an additional four-digit code, known as the ZIP+4 code, to further specify delivery locations.
