Allied Universal Headquarters Address, Corporate Office Location, and Contact Details

About

Allied Universal is the world’s largest private security and facility services company, with its Corporate Headquarters East at 161 Washington Street, Suite 600, Conshohocken, Pennsylvania 19428 and its Corporate Headquarters West at 450 Exchange, Irvine, California 92602 — a dual-headquarters structure reflecting the company’s merger origins and coast-to-coast scale. Allied Universal was formed in August 2016 through the merger of AlliedBarton Security Services and Universal Services of America — two of the largest private security firms in the US — and has since grown through over 70 acquisitions into a global security, staffing, and facility services giant with approximately $23 billion in annual revenue and more than 800,000 employees worldwide. The company is privately held and backed by private equity firm Warburg Pincus, with Global Chairman and CEO Steve Jones having led the business since 1996 — growing it from a $12 million regional company into the world’s dominant security services provider. Allied Universal serves more than 400 Fortune 500 companies across sectors including commercial real estate, healthcare, education, government, retail, energy, transportation, and entertainment, deploying security professionals, mobile patrol, remote monitoring, investigations, technology systems, and facility services from a network spanning more than 100 countries and territories. The company is the third-largest private employer in North America and seventh largest in the world. In 2025, Allied Universal continued its aggressive M&A expansion strategy — acquiring multiple businesses across North America in Q3 alone — and the company has been reported as a potential IPO candidate, though no public offering has been announced as of April 2026.

About the dual-headquarters structure: Allied Universal’s split between Conshohocken, PA and Irvine, CA dates to its 2016 merger — AlliedBarton was headquartered on the East Coast (Pennsylvania) while Universal Services of America was based in California. Rather than consolidating to a single location post-merger, Allied Universal retained both campuses as co-equal headquarters, with the East Coast office managing operations and leadership functions for the eastern US and corporate administration, and the West Coast office anchoring California and western US operations. The Conshohocken campus at 161 Washington Street is a modern multi-tenant office building in the Philadelphia suburb of Conshohocken, Montgomery County — approximately 12 miles northwest of Center City Philadelphia, along the Schuylkill River.
