If a beneficiary asks that we not change his/her address, reinput the old address
exactly as shown on the old MBR. The address will be updated to the MBR and the system
will then post an “X” in the ZIP flag field to prevent the case from being reselected
in the next NCOA matching operation. (For more information on updating the ZIP flag
field see MSOM T2PE 007.024).
For “call-in” letters, input a COA through normal COA procedures. If we do not hear
from the beneficiary, the ZIP flag of “L” will remain on the MBR, and the record will
be reselected for NCOA processing again at some future date. For automatic address
updates, the ZIP flag of “L” will change to “P” when the transaction processes the
update.
