If the beneficiary’s record reflects an uncashed payment within the past 12 months,
SSA sends a notice to the beneficiary inquiring if the check was received and cashed.
If the beneficiary does not respond or indicates a cashed payment, take no further
action. If the beneficiary indicates the payment was not received and not cashed,
SSA technicians will reissue payments or inquiry responses indicating payments were
not received and cashed see, Beneficiary/Recipient Contacts SSA Concerning a Limited
Payability Notice GN 02401.905.
