What u information do they ask on a phone interview for survivor benefits for my 15 yr old daughter in iowa

Hello, Dandy -

You will probably need to make an appointment at the nearest Social Security office and go there to apply for Social Security survivor benefits, because, among other things, you will need to provide a certified copy of the child's birth certificate and a certified copy of the deceased parent's d3@th (have to spell it that way or Fixya considers it a profanity) certificate. See: https://www.ssa.gov/pubs/EN-05-10085.pdf

Also, read the information here:

Best wishes.
