The childs name with have to be the same on their social security card and their birth certificate. Has he seen the birth certificate and social security card ? The reason I ask is because I don't think Mom was able to get the name different on the social security card. A copy of the birth certificate is required when getting a social security card. Were Mom and Dad divorced when the child was born ? If they were, how long had they been divorced ?
If Dad is listed on the birth certificate, it is possible that Mom gave the child her last name. If that is the case, then the birth certificate and social security number will have the same last name.
When a woman gets married, she has a legal document that can be used, if she wants to change her name. When someone has their name legally changed, they have to have it changed on their birth certificate before they can have it changed on their soclai security card.
