Although this form is still accepted by Treasury, SSA's use of this form should be
limited to status or follow-up of a non-critical nature since the Robinson class action
suit shortened the timeframes in which SSA has to respond to beneficiaries.
For critical cases, follow-ups should be handled by querying SSA's system, asking
your RO/PC to query Treasury's Check Payment and Reconciliation system (CP&R), or
by calling Treasury's customer assistance numbers (GN 02406.137B.1.a. above).
