The community is served by a single ZIP code, 42040, making it easy to identify and reach by mail and delivery services.

Location & geography
Farmington is situated in Graves County in the Jackson Purchase region of far western Kentucky, a flat-to-gently-rolling landscape shaped by centuries of agricultural use. The community lies within reasonable driving distance of Mayfield, the Graves County seat, as well as Murray to the southeast, Paducah to the north, and Fulton to the southwest. Farmington covers a total land area of 31.76 square miles and a water area of 0.22 square miles, with small creeks and drainage features typical of this low-lying western Kentucky terrain.
Community & economy
Farmington is a tightly knit rural community where agriculture forms the backbone of daily life, with row crops such as corn, soybeans, and wheat commonly grown across the surrounding countryside. Residents enjoy a slower pace of life with access to local schools, churches, and community gatherings that reinforce the strong sense of neighborly identity found throughout Graves County. Many working families in the area commute to nearby Mayfield or Paducah for employment in manufacturing, healthcare, and retail, while still choosing to call Farmington home for its peaceful setting and affordable land.
Transportation
Farmington is accessible via rural state and county roads that connect it to the broader highway network of western Kentucky, with U.S. Highway 45 and the Purchase Parkway serving as major regional arteries within reasonable distance. The nearest commercial airport is Barkley Regional Airport in Paducah, Kentucky, which offers regional flights and is located approximately 30 to 40 miles north of the Farmington area. Public transit options in this rural setting are limited, making personal vehicle ownership the primary mode of transportation for most residents.
History
Farmington, like many small communities in the Jackson Purchase region, developed in the early to mid-1800s as settlers moved into far western Kentucky following the land purchase negotiated with the Chickasaw Nation in 1818. Agriculture, particularly tobacco and later row crops, drove the local economy for generations and helped shape the rural landscape that still characterizes the area today. The community has remained a stable, if modest, agricultural settlement through the decades, maintaining its rural identity even as nearby cities like Mayfield have grown and modernized.
