What & Why

Why Zip Codes Matter

Zip codes, or Zone Improvement Plan codes, were introduced in the United States in 1963 by the U.S. Postal Service (USPS). Initially designed to streamline mail delivery, zip codes have evolved into essential tools for numerous aspects of modern life.

Mail Delivery: The primary function of a zip code is to ensure that mail reaches its intended destination efficiently. The postal service uses zip codes to sort and route mail, reducing the chances of errors and delays.
Emergency Services: Emergency responders, such as police, fire, and ambulance services, use zip codes to quickly identify the location of incidents and dispatch the appropriate resources.
Demographic Data: Zip codes are used to compile demographic data, providing valuable insights into population distribution, income levels, and other characteristics of a community. This data is used by businesses, government agencies, and researchers for planning and analysis.
Local Services: Many local services, such as trash collection, recycling, and public transportation, are organized based on zip code boundaries.
Online Transactions: When making purchases online, you provide your zip code so that companies can calculate shipping costs and determine if they deliver to your location.
