Credit-reporting agencies operating in New York must register with the state Department of Financial Services by Sept. 15 under a final regulation passed in June to protect state residents’ private data from breaches such as the massive Equifax data breach that exposed information on millions of Americans last year.

DFS launched an online registration form last month for credit-reporting agencies to comply with the new rules issued after public hearings last year, Superintendent Maria Vullo announced recently. The regulations were passed in June in response to the Equifax data breach disclosed a year ago Friday, which exposed the Social Security numbers and other private information of nearly 148 million Americans, including more than 8 million New Yorkers, according to updated figures.
