Standard Federal Regions

The ten standard Federal Regions were established by OMB (Office of Management and Budget) Circular A-105, "Standard Federal Regions," in April, 1974, and required for all executive agencies. In recent years, some agencies have tailored their field structures to meet program needs and facilitate interaction with local, state and regional counterparts. The OMB must still approve any departures, however.
