Origins of the ZIP Code System (National Perspective)

Before ZIP codes, mail sorting relied on manual methods and a less structured system. The rapid increase in mail volume after World War II led to significant bottlenecks. This challenge spurred the USPS (then the Post Office Department) to innovate:

• 1943: Introduction of postal zones for large cities (e.g., "Pekin 1, Illinois").
• 1963: Rollout of the five-digit ZIP Code nationwide, a major technological leap.
• 1983: Implementation of ZIP+4 to further enhance precision and automation.

This evolution underscores a continuous effort to improve efficiency, a standard that the Pekin post office also upholds in its service delivery.

Pekin's Postal History Milestones

• Growth and Expansion: As Pekin grew, its postal services expanded to meet the needs of a burgeoning population and industrial base, especially with its strategic location on the Illinois River.
• Adoption of ZIP Codes: Pekin would have adopted the 5-digit ZIP Code system in 1963, leading to the assignment of 61554 and potentially later 61555 as the city's geographical footprint and mail volume necessitated it.

Understanding this historical arc provides valuable context for the current postal infrastructure within the Pekin IL zip code areas.
