Field Offices (FO), Teleservice Centers (TSC), Processing Centers (PC), or Regional
            Offices (RO) generally become aware of a potential mass loss situation when a pattern
            of nonreceipt allegations develops within specific geographical zip codes. Determining
            mass loss often begins with beneficiaries or recipients contacting SSA with nonreceipt
            allegations. The FOs inform the ROs that a pattern of missing checks has occurred.
            (FOs may communicate the affected SSNs, zip codes, check dates, beneficiary names,
            etc.) The RO PDAS Coordinator receives missing check information directly from the
            FOs. The RO PDAS Coordinator reports the missing checks to the Central Office (CO)
            PDAS Coordinator in the Division of Mail and Logistics Services (DMLS).
         
         
            
               NOTE: Checks normally arrive at the local post office a day or two ahead of the scheduled
                  delivery date. Rarely does USPS notify the (CO) PDAS Coordinator of missing checks,
                  even in cases of theft or destruction.
               
               
             
          
         Once DMLS receives reports of missing checks from the ROs, the CO PDAS Coordinator
            passes the missing check information to the designated USPS PDAS representative. The
            affected RO PDAS coordinator, the CO PDAS coordinator, and the designated USPS PDAS
            representative will remain in communication until the checks are:
         
         
            - 
               
            
- 
               
            
- 
               
            
- 
               
                  • 
                     determined undeliverable. 
 
 
DMLS notifies the Director of the Division of Fraud & Payment Compliance (DFPC) in
            the Office of Financial Policy and Program Integrity (OFPPI) if the delayed checks
            are:
         
         
            - 
               
                  • 
                     for an entire zip code or multiple zip codes; 
 
 
- 
               
                  • 
                     from one or more Regional Financial Centers (RFC); and 
 
 
- 
               
                  • 
                     cannot be located by USPS. 
 
 
DFPC then determines if we must implement a CO Systems Replacement mass loss. For
            information on CO mass loss input, see GN 02406.705D.2. If the agency decides not to implement a CO Systems Replacement mass loss, DFPC informs
            the Office of Analysis, Integration, and Performance Oversight (OAIPO) to apply the
            mass loss nonreceipt input procedures found in GN 02406.705D.1.
