Arlington County, Virginia, is a unique and highly urbanized county known for its close proximity to Washington, D.C., and for housing the Pentagon, the world’s second-largest office building and headquarters of the U.S. Department of Defense. Established in 1801, it operates under a county manager form of government with a five-member County Board elected at-large. The board appoints the County Manager, who acts as the chief executive officer overseeing the administration of county services and policies.

Despite its urban character and population density, Arlington remains wholly unincorporated with no incorporated towns or cities within its borders, a feature that distinguishes it under Virginia law. This status stems from a historical legal decision in the early 20th century affirming the county’s continuous and homogeneous community structure. Arlington has explored the possibility of becoming an independent city due to its urban density.

The county government is organized into various departments and offices, including constitutional officers such as the clerk of court, commissioner of revenue, commonwealth’s attorney, sheriff, and treasurer, each elected to serve the residents of Arlington. The county government emphasizes providing innovative, efficient, and high-quality public services aimed at enhancing residents’ quality of life.

Arlington County boasts a comprehensive organizational structure managed by the County Manager, with leadership focused on governance, public safety, community development, infrastructure, and resident services. The county also maintains a civic engagement approach, ensuring transparency and responsiveness through elected representatives and appointed officials.

The county phone system and other contact points, such as the main phone number 703-228-3130, allow residents to connect with government resources easily. Arlington’s government website provides extensive information on services, leadership, and organizational details to support community involvement and service access.
