My SO tried contacting Chase last year when she turned 18 (I told her not to do it) to try to add her SSN to her supplementary card because she wanted to prove me wrong. Of course, CS denied her this option, and told her Chase does not do that (anymore, if they ever did).

I told her to just wait and let the Credit Agencies work its magic of matching and adding through address and name, and when my Sis in Law applied for a Student Discover Credit Card with her own salary from work at college, she was instantly approved thanks to the Freedom history. Of course, I pulled her 3 credit reports and now they show her SSN, which was added automatically by the credit agencies once she was hard pulled and the unsecured new credit card started reporting to the three agencies (agencies know how to do this).

So do not try to add the SSN through Chase, better let the system work its magic.
