Zip Codes

Zip codes are numerical codes used by postal services to identify specific geographic areas for the purpose of efficient mail delivery. In the United States, a zip code typically consists of five digits, which can be extended to nine digits for more precise delivery locations. The initial digits represent broader regions, while the subsequent numbers narrow down the area to specific post offices or delivery routes. Zip codes are vital for organizing mail distribution and are also used in various applications, including geography, marketing, and demographic analysis.
