We utilize accurate experimental data available in the literature to yield bounds on the polarizabilities of the ground and first excited states of atomic Yb. For the 6s2 1S0 ground state, we find the polarizability alpha to be constrained to 134.4Α144.2 in atomic units, while for the 6s6p 3P0 excited state we find 280.1Α289.9. The uncertainty in each of these values is 1.0. These constraints provide a valuable check for ab initio and semi-empirical methods used to compute polarizabilities and other related properties in Yb.
