By employing a new improved approximation scheme to deal with the centrifugal term, we solve approximately the Klein–Gordon equation with scalar and vector Poschl–Teller potentials for the arbitrary orbital angular momentum number l. The bound state energy equation and the unnormalized radial wave functions have been approximately obtained by using the basic concept of the supersymmetric shape invariance formalism and the function analysis method. We also discuss in detail the identity of the energy spectra for the Poschl–Teller potential in the Klein–Gordon equation and the Dirac equation under the limits of the spin symmetry and pseudospin spin symmetry.
