Why ZIP Codes Matter in Louisville:

4. Demographic and Statistical Data: Government agencies and researchers use ZIP codes to collect and analyze data related to population, income, voting patterns, and public health. ZIP code data can offer insights into the characteristics of specific Louisville neighborhoods.
5. Mapping and Navigation: While GPS systems provide precise coordinates, ZIP codes offer a broader locational context that is still useful for understanding general areas and planning travel within Louisville.
6. Identifying Service Areas: Utility companies, internet providers, and other service providers often define their coverage areas using ZIP codes. Knowing your ZIP code helps determine service availability.

Risks of Incorrect ZIP Codes:

• Delivery Delays: Mail and packages can be significantly delayed.
• Lost Mail: Inaccurate codes increase the risk of mail going missing.
