Experian, Equifax, and TransUnion are the three credit monitoring in the United States. Call, create an account, or log in with each one to place a freeze on your accounts. This helps prevent new lines of credit from being opened in your name. When you need to open new lines of credit such as a home loan or new credit card, you can temporarily unfreeze these accounts with the PIN they provide.
If your personal medical information has been compromised, you should also notify your banks and your health insurance provider so that they have a record of the danger. This helps the companies to properly monitor your account for unusual activity.
