Question: I cannot find any record of a Social Security number for a newly admitted resident. How do I complete item A0600 (Social Security and Medicare Numbers)? Utah Subscriber Answer: You should leave the designated spaces blank, according to the RAI Manual. On page A-14, the manual says: “If no SSN is available for the resident (e.g., if the resident is a recent immigrant or a child) the item may be left blank. Note: A valid SSN should be submitted in A0600A whenever it is available so that resident matching can be performed as accurately as possible” (emphasis original).
