What Does a Zip Code Actually Do?

Zip codes, introduced by the U.S. Postal Service (USPS) in 1963, serve a crucial role in directing mail efficiently. They break down geographic areas into manageable segments, allowing postal workers and automated sorting machines to quickly route mail to its final destination. Beyond mail, zip codes are used by businesses for:

Targeted Marketing: To focus advertising efforts based on geographic location.
Demographic Analysis: To understand customer bases and tailor products/services.
Shipping and Delivery: To calculate shipping costs and ensure accurate delivery.

History and Evolution of Zip Codes

The initial zip codes were a response to the increasing volume of mail. Over the years, the system has evolved, with the introduction of ZIP+4 codes, which add four extra digits to pinpoint a specific delivery route, building, or even a floor in a large building. While 06470 is the primary zip code for Newtown, understanding the broader postal system helps you appreciate the detail and efficiency involved in mail delivery.
