Serving Somerton from our Yuma office
Somerton is the closest of the communities we profile: about 7.5 miles in a straight line from our office at 360 W 20th St to the Census Bureau's reference point for the city (Census Gazetteer, 2025). The city covers about 7 square miles of land, so that point is a fair guide, though the road distance is longer. Call (928) 436-5545 to talk by phone, or visit the office.
What the business data shows, and what it doesn't
Nearly all of Somerton's land, 99.3 percent, is in ZIP 85350. The reverse is not true: only 8.9 percent of the ZIP's land is inside the city, so the ZIP figures below include businesses in the surrounding rural area as well as in Somerton itself (Census 2020 ZIP-to-place relationship file).
- 181 employer establishments had a ZIP 85350 address in 2023; 100 of them had fewer than five employees (Census ZIP Code Business Patterns, 2023, ZIP 85350).
- Construction led the sectors broken out, with 48 establishments, followed by 24 in retail trade, 22 in accommodation and food services, 18 in health care and social assistance, 10 in support activities for agriculture and 9 in transportation and warehousing (same source).
- Employers in the ZIP reported 2,111 paid employees in mid-March 2023 and $80.8 million in annual payroll (same source).
Two gaps are worth knowing. Census business counts exclude crop and animal production, so farms themselves aren't in these numbers; only agriculture-support businesses are. And survey estimates for Somerton residents carry margins of error too wide to publish as precise figures, so we don't.
For county context, agriculture and agribusiness contributed $3.9 billion to the Yuma County economy in 2022 (University of Arizona CALES, 2022 figures, Yuma County).
Funding options that fit Somerton's business mix
Construction and trades
With construction the largest sector count in the ZIP, equipment is a recurring question: work trucks, trailers, loaders, generators and tools. Equipment financing ties the funding to the asset and usually lets the equipment secure the deal. Larger one-time investments, like a yard or a shop build-out, are more often handled with a business term loan. See construction equipment and contractor financing for more.
Shops and restaurants
Retailers and restaurants may weigh inventory financing and card-sales-based offers. A merchant cash advance is not a loan, so put any offer next to loan alternatives before signing.
