As promised, South Carolina taxpayers with children who signed up for the state-sponsored Experian credit monitoring have begun receiving emails or letters inviting them to enroll in Experianís Family Secure service, according to the governorís office and a woman who received an email Thursday. The notifications, which will be staggered over a few weeks, allow adults to enroll all of their associated dependents, as long as they do it by May 31. For children without a credit history, Experian will use their names, addresses, dates of birth and Social Security numbers to monitor whether credit files are created in their names, according to the governorís office.
