To ensure you are placing a freeze on your own credit file, you may be asked personal questions regarding information on your credit report. If the personal information is successfully confirmed, a security freeze or block will be placed on your credit file.
Mail a request for a block on your credit file. You can mail a written request for a security freeze to the credit bureau agencies. You will need to include your name, address, social security number, and date of birth in the request.
