The client is the claimant. Therefore, the claimant's SSN should be entered in the
SSN field of the SPMN. In title II claims, if the claimant is not the NH, use the
auxiliary's or the survivor's own SSN (i.e., BOAN) to establish EVID. In such cases,
enter the NH's SSN in the first “CROSS-REFERENCE SSN” field. See GN 00301.300E.
