In Hive, the SSN validation or ITIN validation is like:

select case when '078051120' rlike '^(?!1{9}|2{9}|3{9}|4{9}|5{9}|6{9}|7{9}|8{9}|9{9}|219099999|078051120|123456789)(?!666|000|9[0-9]{2})[0-9]{3}(?!00)[0-9]{2}(?!0{4})[0-9]{4}$' then 'SSN' 
     when '078051120' rlike '^9[0-9]{2}(7[0-9]|80|81|82|83|84|85|86|87|88)[0-9]{4}$' then 'ITIN' 
     else 'INVLD'
end as ssn_flg;

change the dummy '078051120' to column name of your table.
