It is advisable to monitor financial accounts and statements for any suspicious activity. Regularly reviewing credit reports from the three major credit bureaus (Experian, Equifax, and TransUnion) can help detect unauthorized accounts or inquiries. Placing a fraud alert or a security freeze on credit reports are additional measures that can help prevent new accounts from being opened in your name.
