You're kidding, right? You're going to PAY for info that you can get for FREE? You DO know that people try to rip us off by trying to get us to pay for what is ours for FREE, don't you? I do..... 1-800-772-1213. Number for Social Security. http://www.ssa.gov/ssnumber/ web site for SS. Now you MIGHT not be able to do this on-line, as proof of who you or your daughter are is necessary. Do NOT pay for this info! Well, go ahead and pay for it if you have $$$ to burn-I don't care, but this is something you can do for FREE without the intervention of a 3rd party who wants to charge you.
You may not be able to get your daughter's Social Security number online. However, you may be able to get it over the telephone. You can call the Social Security administration and speak to a representative. The representative will be able to tell you your daughter's Social Security number over the phone after verifying your identity.
If this daughter is a legal dependant of yours by age or disability you can go to ssa.gov and get a replacement with proof. If she isnt your legal dependant and/or is 18 years or older you cannot legally get her number without her permission. To do so would be felony identity theft.
