The Kiwanis International Board of Trustees accepted a proposal to allow the establishment of Circle K Districts on February 22, 1957. The very first Circle K District to be officially recognized was the Texas-Oklahoma District. The second Circle K District was Kentucky-Tennessee which was closely followed by Michigan. Four more Districts were added in the 1957–58 administrative year: Missouri-Arkansas, California-Nevada-Hawaii, Ohio, and Alabama.
