That may be true for landlines but my only phone is a mobile and the bill goes to a business address. They have my name but if that concerns someone it's possible to buy prepaid cellular at Target with cash.
Your mobile is still "listed" and even the prepaid cellulars, as much as cop shows would like us to believe they are virtually untraceable are still " listed" per se.
And that includes buying one with cash, that's another myth that the tv shows would have us believe is common. The fact is that none of the service providers will turn on your service until you register the phone with them, which you do from a landline or a web site, most won't even let you do the activiation from another cell phone. How do they know the difference? Check out NANPA.COM, where the North American Numbering Plan Administration details their numbering schemes for all of the phones in the US.
Could you get one of those phones and somehow spoof the system so that they don't have your name and an address for you, well since part of the rationale behind the use of "pre-paid" wireless phones is to avoid the credit checks that block some people from qualifying for service, then you could probably give a fake name and address and get away with being "unlisted" but that phone would not do much good for you.
The first person you gave the number to so they could call you is a potential list, the first call you make WILL record the numbers called and calling somewhere, not CALLER ID, but the actual details of the call are captured in every switching point from origination to termination, and now you are listed.
Before SS7 was implemented in the 70s and 80s you might have been able to get away without your call details being recorded, but not anymore, and part of those details is the number associated with your registration of that phone, and even if it's a company phone from a business address, they know who they issued that phone to and thus, you're listed.
