## Abstract The implementation of seesaw mechanisms to give mass to neutrinos in the presence of an anomaly‐free U(1)~X~ gauge symmetry is discussed in the context of minimal extensions of the standard model. It is shown that type‐I and type‐III seesaw mechanisms cannot be simultaneously implemente
