They were also referred to as "blood-dols" (blood idols) in reference to the origins of their name (which references the group members' blood types), as well as "paper-dols" (paper idols) because of the paper classification A4. In an effort to distinguish themselves, B1A4 had also promoted a nickname "saessakdol" (새싹돌, "sprout-dol") and created a so-called "saessakchum" (새싹춤, "sprout dance"), which was showcased in various shows including Quiz to Change the World.

On August 31 that year, the group donated 140 kg of rice garlands initially donated by fans to Seoul SOS Youth Camp in Yangcheon District. On September 1, 2012, B1A4 held a mini concert at the Wonju Market to help raise awareness for traditional markets. As they hosted their first solo concert, BABA B1A4, fans from all over the world sent gifts and donations to B1A4, which the group then donated to charity.

On July 19, 2013, as B1A4 prepared for their second solo concert, B1A4 asked fans for school supplies rather than flower wreaths. They were working with CJ Group's charity foundation "Donor's Camp" to support the education of children who are in need.

The group donated part of the proceeds from their third solo concert to Seoul Arts College's matriculation ceremony, which took place on February 27, 2014, at the Olympic Park Olympic Hall.
