We predict the branching ratios of the Z -> e(+/-) mu(+/-), Z -> e(+/-) tau(+/-) and Z -> mu(+/-)tau(+/-) decays in the model III version of the two Higgs doublet model, with the inclusion of one and two spatial non-universal extra dimensions. We observe that the branching ratios are not sensitive to a single extra dimension, however, this sensitivity is considerable for two extra dimensions.
