Recent theoretical results have demonstrated that noncommutative geometries naturally appear within the context of string or M theory. One consequence of this possibility is that QED takes on a non-Abelian nature due to the introduction of 3- and 4-point functions. In addition, each QED vertex acquires a momentum dependent phase factor. We parametrize the effects of noncommutative space-time coordinates and show that they lead to observable signatures in several 2 -->2 QED processes in e(+)e(-) collisions. In particular, we examine pair annihilation, Moller and Bhabha scattering, as well as gamma gamma --> gamma gamma scattering and show that noncommutative scales of order a TeV can be probed at high energy linear colliders.
