When enrolling your kids in school or sports, you may want to think twice before handing over their birth certificate or Social Security card. Just because they’re children doesn’t mean they’re too young to have valuable personal information stolen. Even infants are at risk. Identity thieves are targeting the inactive Social Security numbers of children. According to the Identity Theft Resource Center, thieves who purchase these Social Security numbers have little or no trouble opening accounts, since banks and other issuers of credit have no way to verify the age of an applicant. A pre-approved credit card offer in your toddler’s name might seem like a funny mistake but it can also be a red flag. And if your kid uses the Internet unsupervised, have a talk with them about what information is safe to give out and what isn’t. Financial experts recommend checking your children’s credit reports every year. You can also put a block on their reports, so people can’t use their Social Security numbers and names to obtain credit.
