A detailed analysis of anomalous U(1)'s and their effective couplings isperformed both in field theory and string theory. It is motivated by thepossible relevance of such couplings in particle physics, as well as apotential signal distinguishing string theory from other UV options. The mostgeneral anomaly related effective action is analyzed and parameterized. Itcontains Stuckelberg, axionic and Chern-Simons-like couplings. It is shown thatsuch couplings are generically non-trivial in orientifold string vacua and arenot in general fixed by anomalies. A similar analysis in quantum field theoriesprovides similar couplings. The trilinear gauge boson couplings are alsocalculated and their phenomenological relevance is advocated. We do not findqualitative differences between string and field theory in this sector.Comment: 52 pages, 2 eps figures, LaTeX, feynmf & youngtab packages (v2 - Minor corrections, references added
