The most authoritative source for zip code boundaries is always the United States Postal Service (USPS). They provide detailed maps and lookup tools that allow users to enter an address and receive the precise zip code. Local government portals, such as the City of Kennewick's official website, may also offer resources or links to relevant geographic information systems (GIS) that display these boundaries.

Why Zip Codes Matter for Mail, Deliveries, and Services

Beyond simply directing mail, Kennewick's zip codes play a far more significant role in daily life and economic activity. They are a fundamental geographic identifier with wide-ranging implications.

• Efficient Mail Delivery: This is the most obvious function. Correct zip codes ensure letters and packages reach their intended recipients quickly and accurately, preventing delays or misdeliveries.
• Shipping and Logistics: Businesses rely heavily on accurate Kennewick postal codes for calculating shipping costs, optimizing delivery routes, and managing inventory. E-commerce platforms, for example, often use zip codes to determine eligible delivery services and estimated arrival times.
• Insurance and Property Values: Zip codes are often factors in determining insurance premiums for auto, home, and business policies due to varying risk profiles across different areas.

Our analysis of local real estate data confirms that properties in 99337, for example, often reflect different average market values compared to 99336.
