Abstract We construct a low-scale seesaw model to generate the masses of active neutrinos based on flavor symmetry supplemented by the group, capable of reproducing the low-energy Standard Model (SM) fermion flavor data. The masses of the SM fermions and the fermionic mixing parameters are generated from a Froggatt–Nielsen mechanism after spontaneous breaking of the group. The obtained values for the physical observables of the quark and lepton sectors are in good agreement with the most recent experimental data. The leptonic Dirac CP-violating phase is predicted to be and the predictions for the absolute neutrino masses in the model can also saturate the recent constraints.
