Eastvale is continuing its long-standing effort to obtain a unique ZIP code, according to an April 27 announcement. Mayor Pro Tem Clint Lorimore, council member Mike McMinn, and city staff recently traveled to Washington, D.C., where they met with Senators, members of Congress, and their staff about changing existing ZIP code boundaries.
The issue is significant for Eastvale because sharing ZIP codes with neighboring cities has led to mail delivery errors, miscalculated sales taxes and insurance rates, and challenges for emergency responders. Since incorporating 16 years ago, Eastvale has shared the 91752 ZIP code with Mira Loma and Jurupa Valley and the 92880 ZIP code with Corona and Chino. This situation has caused confusion for residents and businesses alike.
Lorimore said that after years of setbacks there may be new momentum on the issue. “I’ve been on the council for 12 years, and the boundaries have always been an issue,” Lorimore said. “I’m always asked about it, especially by business owners. Everyone wants to know when we’re going to get this done.” He added that feedback from recent meetings in Washington was positive: “We received a lot of positive feedback from the staff members we talked to,” Lorimore said. “This time it feels like it has legs. I really believe we’re going to get it done.”
Legislative efforts are underway at both federal levels: Representatives Ken Calvert (R-Corona) and Norma Torres (D-Ontario) reintroduced legislation in February 2025 aimed at establishing one ZIP code for Eastvale after a previous attempt failed two years earlier. “The lack of a unique ZIP code that properly identifies Eastvale continues to negatively impact residents and businesses,” Calvert said when introducing the bill.
Other bills addressing similar issues are also being considered in Congress; HR 672 passed the House in July before moving on for Senate review. Alexander Fung, Eastvale’s economic development director, said these legislative actions could resolve not only Eastvale’s concerns but also those of other cities facing similar problems.
Local business owner Kay Trotman described ongoing difficulties caused by overlapping postal codes: “Yes, I’ve had a lot of issues with the Zip code problem,” Trotman said. She explained that clients often question her business address due to confusion between city names linked with different ZIP codes.
Looking ahead, Fung expressed optimism about progress in Congress: “The (Homeland Security) committee has expressed interest in moving the bill forward, maybe in the next few months,” he said. “We’ve never been this far in legislative process before. We’re going to remain optimistic, and we’re going to keep pushing.”
