Neutrino oscillations provided the first evidence for the violation of flavour in the lepton sector, and established a clear need to consider
extensions of the Standard Model. Many new phenomena can emerge from these New Physics (NP) constructions, among which
processes violating lepton number and charged lepton flavour, all clear signals of New Physics. Following a short overview of the status of experimental searches, we comment on the prospects of several models of massive neutrinos, from minimal constructions to complete NP models, to the above mentioned observables.
