What Is a PEO Directory?
A PEO directory is a database of Professional Employer Organizations (PEOs) — companies that provide co-employment services including payroll processing, HR administration, employee benefits management, and employer compliance to small and mid-sized businesses.
The PHRBO PEO Directory lists exclusively US-based PEO operators, organized by state coverage footprint, industry specialization, and employer size served. Employers use this directory to find and compare PEO providers operating in their state. PEO vendors use it to list their services and reach employers actively searching for co-employment partners.
Find Your Co-Employment Partner
Finding the right PEO is not a simple Google search. Most PEO vendors have limited SEO visibility outside their home state. National PEO comparison sites frequently include HR software vendors, staffing agencies, and EOR providers that are not true co-employment operators. Generic business directories do not filter by state licensure, FEIN-based payroll operation, or co-employment service scope.
A dedicated PEO directory solves all three problems. Every vendor listed here has been reviewed against PEO eligibility criteria. Every profile displays the state coverage footprint, service scope, and industry specializations that matter most to an employer evaluating co-employment options.
