For the millionth time, NO, if all you have is the mobile phone number, you cannot get the IP address!
Even if you could get the IP address, having it is virtually useless. You can't "track" the IP address to it's actual location or do much of anything else and the next time the person's phone connects back to the cellular network, the IP address will be different.
First of all, this has nothing to do with the question asked: "Can I get an IP address with just their phone number?"
Secondly, a trace route will NOT tell you the city state and zip code they are in.. It will tell you the city state, and zip code of the company that owns that IP address. Often, this will be near where the person lives, but not always, and there is no way to know. If the person was using a smartphone or tablet with a moblile data plan, it will be nowhere near them..
So, good try, but pretty useless info.
