  We explore the capabilities of the LHC and the Linear Collider(LC) to
distinguish the production of Kaluza-Klein(KK) excitations from an ordinary
$Z'$ within the context of theories with TeV scale extra dimensions. At the
LHC, these states are directly produced in the Drell-Yan channel while at the
LC the effects of their exchanges are indirectly felt as new contact
interactions in processes such as $e^+e^-\to f\bar f$. While we demonstrate
that the LC is somewhat more capable at KK/$Z'$ differentiation than is the
LHC, the simplest LC analysis relies upon the LHC data for the resonance mass
as an important necessary input.
