We study SU(4)(C) x SU(2)(L) x U(1)(R) models with modular A(4) symmetry that provide a unified description of the quark and lepton sectors including the flavor structures. The models are distinguished by the assignments of the modular weight to matter superfields. We carry out numerical chi(2) analysis and search for parameter sets that accommodate the experimental results. We provide a benchmark point for each model to illustrate the implications of our models.
