Abstract For a 2-edge-connected graph G, the group connectivity number of G is defined as Λ g (G) = min{k : G is A-connected for every abelian group with |A| ≥ k}. Let G • H denote the semistrong product of two graphs G and H. In this paper, we extend the result of Yan et al. [Int. J.  Algebra 4 (2010), 1185-1200] on group connectivity in Cartesian product of graphs to semistrong products and make a slightly stronger conclusion
