To promote the release of Exodus, a series of videos referred to as "Pathcode", featuring one Exo member each and are set in various locations, were released on YouTube.

The Korean and Chinese music videos for "Call Me Baby" were released on March 30, 2015.

Writing for Billboard, Jeff Benjamin commented that while "Call Me Baby" "sounds wholly inspired by the late '90s/early '00s sound", Exo "is not only bringing in the nostalgic feel, but doing it at a 200 percent intensity."^[8] The song reached number two on both South Korea's Gaon Digital Chart and the Billboard World Digital Songs chart.^[9][10] It also entered the Canadian Hot 100 at number 98, making Exo the second South Korean artist, after Psy, to appear on the chart.^[11] "Call Me Baby" went on to win first place 18 times in total on South Korean music TV shows for the entire month, and the all-time second highest number of wins.^{[citation needed]} Billboard ranked the song at number 9 on their list of top 20 K-pop songs of 2015.^[12]
