We study the prospects of searching for leptophilic gauge bosons (LGBs) at the beam dump experiment using e± beams of International e+e− Linear Collider (ILC). We consider LGBs in association of U(1)e−μ, U(1)e−τ, and U(1)μ−τ gauge symmetries, which are assumed to be light and long-lived. Utilizing the energetic electron and positron beams of the ILC, we show that the ILC beam dump experiment can cover the parameter regions which have not been explored before. We also discuss the possibility of distinguishing various models.
