  We discuss radiative neutrino mass models with a general lepton flavor
dependent $U(1)$ gauge symmetry. The scotogenic model is adopted for neutrino
mass generation in which $Z_2$ odd singlet fermions and an inert scalar doublet
are introduced. A lepton flavor dependent local $U(1)$ symmetry is applied to
realize two-zero texture of a Majorana mass matrix of $Z_2$ odd singlet
fermions where we explore minimal construction choosing $U(1)$ charges of the
standard model fermions and singlet fermions. Then we investigate neutrino mass
matrix and show some predictions for constructed models, and discuss some
phenomenological implications.
