Automated F-stops apply to Title XVI checks only. When nonreceipt is alleged, SSA
inputs a B-stop (unless a C-stop is warranted – see GN 02406.150) and the Department of the Treasury (DT) issues a courtesy check before the status
of the original check is known. When the original check is subsequently cashed, the
SSI system automatically places an F-stop on the replacement check.
In Title II, the Program Service Center (PSC) must manually input the F-stop on the
replacement check. DT sends the claims package for the cashed original to the jurisdictional
PSC. An alert also goes to the Field Office (FO) that the original check was cashed
which prompts the FO to send an MDW to the jurisdictional PSC to input the F-stop
on the replacement.
