   RS 01602.530 Evaluation of Railroad Retirement Board (RRB) Evidence
   
   
   
   We have more restrictive non-disability evidentiary requirements for entitlement than
      the RRB. RRB's current evidentiary procedures do not meet our minimum certification
      standards. Therefore, we can only accept as secondary evidence, RRB certified photocopies
      of non-disability evidentiary documents affecting SSA entitlement, if RRB is not the
      custodian of the system of records. For more information on evidentiary standards,
      see GN 00301.015 through GN 00301.030. We accept as primary evidence, original documents certified by the proper custodian
      of the system of records (such as a public record of birth certified by the State
      or county registrar). We evaluate the evidence received from RRB without consideration
      of RRB evidentiary standards. However, we accept the RR earnings as posted on the
      earnings record.
