The SSA-2490-BK is available through the modernized claims system (MCS), but the MCS
version may only be used when the number holder (NH) is filing for
U.S. retirement or disability Totalization benefits alone, or
U.S. retirement or disability benefits (regular or Totalization) and concurrently
for Swiss benefits.
The MCS version of the SSA-2490-BK may not be used to file for
U.S. or Swiss survivors benefits.
A paper or electronic SSA-2490-BK application form must be used in the latter cases.
NOTE: It is not necessary to take an SSA-2490-BK in claims for U.S. auxiliary benefits
in life cases or in survivor cases where there was a previously approved award in
a life case since this application would have been completed previously in connection
with the NH's claim.
