They will then conduct their investigation. Then you will need to remember when to update those files, as the credit companies will only keep the information for only a limited amount of time, after which it will be automatically dropped. I have even left off my social security number from my driver's license, and either the DMV missed that, or they already have it in their file. I was very careful to never give any computer my name or address or other identifying information. I always use some ridiculous name, such as a cartoon character, or nickname used between friends, or some other non-identifying info.
Passwords are also non-identifying, no birthdates or addresses, or anything similar.
Yet time warner's on-line site asks for it. I have just set up a younger cousin's brand new Dell P-II 450 computer, and was appalled at all of the personal information it asked for. Of course everything I entered was fake. I have also never registered any software or hardware, and have never returned a warranty registration certificate. I have only purchased a computer after being forced to because a device I used for my company required to be downloaded to a computer for processing the data.
