Eastvale currently has two Zoning Improvement Plan (ZIP) codes, 91752 and 92880, that were previously assigned by the United States Postal Service (USPS). ZIP Code 91752 represents the former Mira Loma unincorporated community that is shared between the Cities of Eastvale and Jurupa Valley; however, Mira Loma no longer exists as an unincorporated area after both cities incorporated. ZIP Code 92880 is currently shared between the Cities of Chino, Corona, and Eastvale and small portions of unincorporated Orange County and Riverside County.

After many months of advocacy, the USPS has revised the 92880 ZIP code to accurately register as Eastvale, California starting on January 1, 2024. Various wayfinding platforms, companies, and government agencies are in the process of switching 92880's designation from "Corona" to "Eastvale."  Resident and businesses in the 92880 ZIP Code can now list “Eastvale” as the city name in their addresses. We encourage you to review the full press release to learn more. 

At the moment, the City remains home to both ZIP codes 91752 and 92880. Despite 92880’s designation change, residents and businesses in ZIP Code 91752 continue to experience challenges. The City also continues to receive reports from 92880 residents regarding insurance premium rate mismatches as a result of sharing ZIP codes with nearby cities. The City is diligently working with our federal representatives to introduce legislation in the current congressional legislative session to address the City’s outstanding ZIP code challenges. Congressman Ken Calvert and Congresswoman Norma Torres, both representing Eastvale in the U.S. House of Representatives in Congress, worked with other legislators in Washington, D.C. to introduce H.R. 672 on January 23, 2025 and, H.R. 1225 on February 12, 2025. Additionally, U.S. Senator Alex Padilla collaborated with other federal legislators to introduce S. 1455 in the Senate, which serves as a companion bill to H.R. 672.  

H.R. 672 and S. 1455 were introduced to address ZIP code challenges in several cities and communities across the nation, including Eastvale. H.R. 1225 was introduced to specifically address ZIP code challenges in Eastvale. If either of these bills pass, Eastvale will be granted a new and independent ZIP code.

On July 21, 2025, the U.S. House of Representatives recognized the importance of addressing Eastvale’s ZIP code challenges and unanimously passed H.R. 672. This bill is now being directed to the Senate for review. The City commits to working with federal partners to increase awareness and encourage congressional support for the City's ZIP code legislation.

National ZIP Code Advocacy Coalition

The City of Eastvale founded and currently co-chairs an informal working group, known as the National ZIP Code Advocacy Coalition, which is comprised of more than 80 municipalities from across more than 30 states. Many of these municipalities share similar issues as a result of sharing ZIP codes with neighboring jurisdictions and are working together to exchange innovative and creative ideas to advance advocacy efforts. The Coalition presents an unique opportunity for the City to leverage resources and connections from other states to garner support from federal legislators.  To learn more about the National ZIP Code Advocacy Coalition, click here.

How You Can Help

In order for Eastvale to have the greatest chance into obtaining an independent ZIP code, the U.S. Congress must enact legislation to officially consolidate the City’s ZIP code boundaries. The City encourages residents and community groups to submit letters supporting the City having its own independent ZIP code. These letters and comments greatly demonstrate that the community supports the City’s endeavor. Letters of support can be filled out using the link below or emailed to the City’s Economic Development Manager, Alexander Fung, at afung@eastvaleca.gov.

Affected residents, businesses, and stakeholders are encouraged to submit testimonies on how the lack of an independent ZIP code has impacted them personally. Testimonies can also be submitted using the link below.
