Barter 6 features guest appearances from Birdman, T.I., Boosie Badazz, Young Dolph, Yak Gotti, Lil Duke and Jacquees, while the production was handled primarily by in-house producers London on da Track and Wheezy, among others.

[1] Following a threat of legal action, Thug announced days prior to the release that the project was to be re-titled Barter 6, in line with the typical Blood gang practice of replacing the letter "C" with "B".

[7] The mixtape's lead single, "Check", was released on April 1, 2015, as well an accompanying music video,[8] the song peaked at number 100 on the US Billboard Hot 100.

[10] Complex said "on Barter 6, a rapper frequently dismissed as a druggie dance trapper inverts himself, yielding a passionate and personal record", adding that his "visceral illustrations are one-of-a-kind, and he communicates joy, frustration, and dread with unique clarity".

[19] Rolling Stone critic Joe Levy said most of the songs sound "boastful and sad in the same moment", abandoning the frenzied tunefulness of Young Thug's past work in favor of indistinctly "syrupy tracks".
