I think your husband is right to worry. I never received a phone call from SSA. Only a letter in the mail when I received my favorable judgment. It also sounds VERY strange for SSA to ask about your SSN. They are, after all, the government agency that assigned it to you. And driver's license number? What in the world do they need that for?

I'm sorry to say that you may have become a victim of identity theft. Let your bank and credit card companies know right away!
