In a minimal extension of the standard model in which new neutral fermions have been introduced, we show that the requirement of vanishing anomalies fixes the hypercharges of all fermions uniquely. This naturally leads to electric charge quantization in this minimal scenario which has features similar to the standard model: invariance under the gauge group SU(2)[sub [ital L]][direct product]U(1)[sub [ital Y]], conservation of the total lepton number, and masslessness for the ordinary neutrinos. Such minimal models might arise as low-energy realizations of some heterotic superstring models or SO(10) grand unified theories.
