NEW YORK — They might not be old enough to swipe a credit card or take out a loan, but you still need to keep an eye on your little one’s credit. Kids can be victims of identity theft, too, and it often goes unnoticed by parents for years. Typically, a youngster doesn’t find out something is wrong with their credit until they grow up and get rejected for a student loan or isn’t able to get a credit card. “By the time the kid finds out, their credit has already been massacred,” says Adam Levin, founder of identity theft recovery service IDT911. All thieves need to obtain a fraudulent credit card or other loan is a child’s Social Security number, says Eva Velasquez, president and CEO of The Identity Theft Resource Center, a non-profit that helps identity theft victims. Crooks like to target children because they know they can get away with it longer and open several accounts. HOW COMMON IS CHILD IDENTITY THEFT?
