AlliedBarton Address And Corporate Headquarters Location Guide For 2026

Note: AlliedBarton Security Services formally merged with Universal Services of America in 2016 to form Allied Universal. Consequently, inquiries regarding the legacy AlliedBarton address now point to the corporate headquarters of Allied Universal, though regional offices continue to manage localized security operations globally in 2026.

Navigating corporate addresses, regional office locations, and official mailing destinations requires precise geographical and operational data. Whether you are submitting legal documentation, processing payroll inquiries, verifying employment records, or seeking local security contract consultations, identifying the correct corporate facility ensures your correspondence reaches the appropriate department without administrative delay. This guide provides an exhaustive breakdown of the historical context, current corporate headquarters, regional mapping, and verification protocols for AlliedBarton and its parent organization, Allied Universal, as of 2026.

Evolution from AlliedBarton to Allied Universal: Corporate History and Headquarters

Understanding the correct physical address requires a brief examination of the corporate evolution that shaped the modern security landscape. AlliedBarton Security Services was once one of the largest American security guard and facility services companies. In May 2016, a massive merger combined AlliedBarton with Universal Services of America, creating a unified global giant operating under the name Allied Universal.

Because of this structural consolidation, legacy mailing addresses for AlliedBarton have been transitioned to central corporate hubs or integrated into regional Allied Universal branch networks. Sending mail to obsolete local office addresses can result in significant processing delays or returned correspondence.

The dual corporate headquarters model maintains administrative efficiency across North America. The primary executive and administrative mailing addresses for official corporate correspondence are detailed below.

Official Corporate Headquarters Addresses

For formal legal notices, corporate partnerships, vendor contracting, or executive-level communications, correspondence must be directed to the primary administrative offices. Allied Universal maintains dual corporate headquarters to manage its expansive eastern and western operations.

Eastern Corporate Headquarters

• Company Name: Allied Universal (Successor to AlliedBarton)
• Street Address: 151 North Delaware Avenue, Suite 600
• City, State, Zip Code: Conshohocken, PA 19428
• Primary Focus: Executive administration, legal compliance, corporate development, and eastern regional oversight.

Western Corporate Headquarters

• Company Name: Allied Universal
• Street Address: 3530 Fashion Way
• City, State, Zip Code: Santa Ana, CA 92704
• Primary Focus: Operational logistics, technological infrastructure, national client accounts, and western regional management.

When dispatching sensitive documents, always verify whether your point of contact operates out of the Pennsylvania or California executive hubs, or if your inquiry should be routed to a local regional field office.

Locating Regional Branch Offices and Local Facilities

While corporate headquarters manage high-level governance, day-to-day security guard deployment, local account management, and branch-level human resources are handled through an extensive network of regional field offices. If you need to visit a physical facility for uniform pickup, in-person interviews, or local operational meetings, utilizing the corporate address will not suffice.

Steps to Identify Your Local Regional Office

1. Access the Official Web Portal: Navigate to the corporate Allied Universal locator tool online to search by ZIP code or city.
2. Identify Your Service Division: Determine whether your inquiry falls under physical security, event staffing, or electronic security systems, as physical office locations may differ.
3. Verify Operating Hours: Regional offices operate under strict administrative schedules, typically Monday through Friday, 8:00 AM to 5:00 PM local time.
4. Schedule an Appointment: Unannounced visits for HR or payroll disputes are generally discouraged; always secure an appointment confirmation via phone or email before traveling to a field facility.

Employment Verification, Payroll, and HR Mailing Contacts

Current and former employees searching for the legacy AlliedBarton address often require assistance with W-2 retrieval, payroll adjustments, employment verification (The Work Number), or human resources grievances. Sending these requests to the general executive headquarters slows down processing times.

Human Resources Best Practice: For fast and secure employment verification, third-party lenders and government agencies should utilize automated electronic verification platforms designated by the corporation rather than physical mail. Standard processing times for physical correspondence sent to corporate HR departments range from 10 to 15 business days.

• Payroll and W-2 Inquiries: Managed through the internal employee self-service portal or routed directly to the centralized payroll administration center in Santa Ana, CA.
• Employment Verification: Processed digitally via authorized third-party verification networks using the employer code assigned to Allied Universal (incorporating legacy AlliedBarton records).
• Workers Compensation Claims: Must be reported immediately through the 24/7 dedicated employee injury hotline rather than via standard postal mail to ensure legal compliance and medical authorization.
