We attribute deviations of the muon and electron magnetic moments from thetheoretical predictions to the presence of an additional $U(1)^\prime$supersymmetric model. We interpret the discrepancies between the muon andelectron anomalous magnetic moments to be due to the presence of non-universal$U(1)^\prime$ charges. In a minimally extended model, we show that requiringboth deviations to be satisfied imposes constraints on the spectrum of themodel, in particular on dark matter candidates and slepton masses and ordering.Choosing three benchmarks with distinct dark matter features, we studyimplications of the model at colliders, concentrating on variables that candistinguish our non-universal scenario from other $U(1)^\prime$implementations.
