Undeliverable checks, mail, reports of change or a change of address (COA) indicate
changes in a recipient's circumstances which may affect SSI eligibility or payment
amount. A suspension of SSI eligibility for “whereabouts unknown” (payment status
code S06) is proper when we cannot locate a recipient and determine his or her current
SSI eligibility and correct benefit amount.
IMPORTANT: Follow the instructions in this section as far as you can to locate a recipient
before suspending benefits S06. An FO input of S06 in the PS field (or the Payment Status
Page) or an FO returned check input using the Direct SSR Update in MSSICS will suspend
SSI. (Note that the system will automatically process a record to S06 when the U.S.
Treasury Department returns a check for an address reason.)
NOTE: Do not use S06 for a representative payee address problem. Consider the need for a
new payee as soon as it appears that a payee is missing or no longer acting on behalf
of the recipient. Use direct payment when possible, GN 00504.105. Stop payments temporarily (S08) until you can find a new payee if direct payment
is not permitted. (GN 00504.110).”
