The double-lepton polarization asymmetries for the exclusive B -> K(1)l(+)l(-) transition is studied in the universal extra dimension. It is shown that most of the double-lepton polarization asymmetries are sensitive to the model parameters. Any experimental measurements on double-lepton polarizations and their comparison with theoretical results can give valuable information on the physics beyond the standard model.
