Understanding the Pomona zip code is crucial for mailing, real estate transactions, and understanding neighborhood boundaries. The primary zip code for Pomona, California, is 91767, which covers the majority of the city. Adjacent areas may also use 91768 and 91766. This guide provides a clear breakdown to ensure your correspondence and property searches are accurately targeted.
A ZIP Code is a system of postal codes used by the United States Postal Service (USPS). For home buyers and sellers, knowing the correct zip code is essential for pricing comparisons, as property values can vary even within the same city based on these postal boundaries.
The central and most widely recognized Pomona zip code is 91767. This code encompasses the city's downtown core, residential neighborhoods, and California State Polytechnic University, Pomona (Cal Poly Pomona). When searching for real estate listings or sending mail to a Pomona address without a specific zip code, 91767 is the most common default. It's important to verify the exact code with the USPS or your real estate agent, as postal boundaries don't always align perfectly with city limits.
While 91767 is dominant, parts of Pomona fall under two other zip codes. The area sometimes referred to as North Pomona may use 91768. Additionally, a small section on the city's edge might be served by the 91766 zip code, which is primarily associated with the nearby community of Diamond Bar. The following table summarizes the primary zip codes associated with Pomona:
| Zip Code | Primary Coverage Area |
|---|---|
| 91767 | Central Pomona, Downtown, Cal Poly Pomona |
| 91768 | Northern areas of Pomona |
| 91766 | Eastern edges (shared with Diamond Bar) |
In real estate, zip codes are more than just mailing addresses; they are key data points for market analysis. Property values, school district boundaries, and demographic information are often organized by zip code. A buyer comparing homes in 91767 versus 91768 might find differences in average sale prices or neighborhood characteristics. Real estate agents and online portals use this data to help clients make informed decisions. Furthermore, mortgage lenders and insurance companies may use zip codes to assess risk and determine rates.
To ensure absolute accuracy, especially for important documents like purchase contracts or mortgage applications, always double-check the zip code. The most reliable method is to use the official USPS Zip Code Lookup tool on their website. Simply enter the full street address to get the correct code. Relying on general internet searches can sometimes lead to errors, particularly for properties near city borders.
Accurately using the Pomona zip code—primarily 91767—is fundamental for effective communication and informed real estate decisions. Verifying the code through the USPS ensures mail delivery and precise property valuation. Understanding these postal boundaries provides a clearer picture of the local market landscape.
