If the claimant's whereabouts become unknown anytime during the redetermination/readjudication
process, make reasonable efforts to locate the claimant. See DI 11018.005, which requires a personal contact at claimant's residence, contacts with the postmaster,
neighbors, physician, local tradesmen, others. If the claimant cannot be located,
record the efforts made and evaluate the claim(s) on the basis of the evidence in
file. (See also DI 23005.001.) Document attempts to locate the claimant to enable the DDS to make a determination.
