The CPN is a nine-digit number that has the exact same genetic makeup of a Social Security Number. This is not a government issued number like an EIN or TIN. This number is NOT a new social and NOT a tax ID or EIN. It is simply an available file number at the credit bureaus that can have financial information reported. You have the right to establish this number only once, so do not abuse it. This explanation is not here to advise anyone to misrepresent your Social Security Number, as you are completely responsible for any debts you incur using your Credit Privacy Number. It is your legal right to keep your Social Security Number private, and use a separate number for any credit related purposes. You are only required by law to disclose your Social Security Number to the Internal Revenue Service, your employer, when registering a motor vehicle, buying a firearm, or applying and obtaining a federally-insured loan such as FHA, Sallie Mae, etc. I encourage you to use the laws to your advantage. Each credit bureau works on a different schedule. In addition, the CPN is used by celebrities, congress members/government workers, and witness protection reasons. For example, celebrities use it because the media can use their SS# to track what they are buying and where they are simply by tracking their credit cards. Further, in example, congress holds special privileges to the law; therefore, their privacy needs to be protected. In another example, witnesses under protection can be located if they use their true social security number for transaction. This is the reason why there is the existence of a Credit Privacy Number program.
