Robert Kolarik of the San Antonio Express-News wrote that the film start off well but loses its way once it starts to fill in the courier's back story. Gabe Toro of Indiewire rated it D+ and wrote that the film "almost seems embarrassed by its content". Tyler Foster of DVD Talk rated it 1.5/5 stars and wrote, "The Courier is a tired thriller, filled with tired actors playing tired characters, wrapped up in a tired story." Gordon Sullivan of DVD Verdict called it "a thoroughly average B-action-thriller" of interest only to Morgan's fans.
