N2 - Using an electron-positron collision data sample corresponding to (1.0087\pm0.0044)\times10^{10} J/\psi events collected using the BESIII detector at the BEPCII collider, we firstly search for the lepton number violation decay phi \to \pi^+ \pi^+ e^- e^-J/\psi\to \phi\eta No obviously signals are found. The upper limit on the branching fraction of phi \to \pi^+ \pi^+ e^- e^- 1.3\times10^{-5} at the 90% confidence level.
