History of Zip Codes in Washington

The Evolution of Zip Codes

The zip code system, introduced by the United States Postal Service (USPS) in 1963, revolutionized mail delivery. Before zip codes, postal zones were used in large cities, but these were limited and often led to inefficiencies. The introduction of the five-digit zip code system streamlined the process, allowing for more precise sorting and delivery.

Key Milestones

Washington State saw its own share of milestones in the evolution of zip codes. Initially, major cities like Seattle and Spokane received their unique codes. Over time, as the population grew and urban areas expanded, more zip codes were introduced to accommodate new neighborhoods and suburban regions.

Understanding Zip Codes

What is a Zip Code?

A zip code is a numerical code used by the USPS to identify specific geographic areas for the purpose of sorting and delivering mail. The term “ZIP” stands for “Zone Improvement Plan,” reflecting the system’s goal of improving efficiency.

Structure of a Zip Code

The standard zip code consists of five digits. For example, the zip code for downtown Seattle is 98101. In some cases, an extended version known as ZIP+4 is used, which includes a hyphen and four additional digits to provide even more precise location information.
