What is a Zip Code?

Zip codes, which stands for Zone Improvement Plan codes, are a system used by the United States Postal Service (USPS) to efficiently sort and deliver mail. They were introduced in 1963 and have since become a crucial part of the address system. Understanding zip codes can make your life easier, especially when shipping or receiving packages.

History and Purpose of Zip Codes

The USPS implemented zip codes to streamline mail sorting and delivery. Before zip codes, sorting mail was a manual, time-consuming process. The introduction of zip codes significantly improved efficiency. According to USPS data, this system has saved countless hours and resources over the years.

The Structure of a Zip Code

A standard zip code consists of five digits. Each digit represents a specific geographic area. The first digit identifies a group of states or regions. The second and third digits together indicate a sectional center facility (SCF), which is a processing and distribution center. The final two digits narrow down the specific post office or delivery area within that SCF. The extended zip code is a nine-digit code, with the additional four digits further specifying a delivery sector and unit, like a building or a specific street.
