We investigate the edge group irregularity strength (esg(G)) of graphs, i.e. the smallest value of s such that taking any Abelian group G of order s, there exists a function f:V(G)→ G such that the sums of vertex labels at every edge are distinct. In this note we provide some upper bounds on esg(G) as well as for edge irregularity strength es(G) and harmonious order \rmhar(G).
