About this file

Written by GovTribe AI ·

This document is a comprehensive field office locations guide for the Defense Counterintelligence and Security Agency (DCSA), updated on April 7, 2021. The document details the agency's field offices across four regions: Capital, Northern, Southern, and Western, providing specific contact information, phone numbers, and geographic areas of responsibility (AOR) for each office. The field offices cover virtually all U.S. states, territories, and specific counties, with each office having a designated symbol, location, phone number, and precise mailing address.

The guide is organized into regional sections, with each section containing multiple field offices responsible for different geographic territories. Offices are located in states such as Virginia, Maryland, Massachusetts, New York, Georgia, Texas, California, and others, with some offices covering multiple states or specific regions within states. Each field office has a dedicated email address for communication, and the document provides granular details about which specific cities, counties, and regions fall under each office's jurisdiction, enabling precise operational coverage across the United States and its territories.
