Why Are Zip Codes Important?
The United States Postal Service (USPS) uses zip codes to efficiently transport mail and parcels. They’ve also been used to split individuals into groups and stratify data, allowing marketers, researchers, and corporations to separate populations by region for better efficiency.
Also, the zip code is widely recognized as an important piece of information for determining delivery routes and locations. It may be used in marketing to segment customers based on where they reside. This data can assist firms in focusing their efforts on client categories that have the highest likelihood of maintaining their business.
