Can I find my iPhone by tracking its phone number? - 1

Alright, so my dad's on vacay and he's the only one who might know the iCloud info.
The sad part is that, he doesn't remember his info, so iCloud would be useless.
The most I can think of, besides all the complicated apps and whatever, is to track the phone number. I'm not sure how besides going to the police, but I'm not sure if my idea is possible.
I just really my iPhone 5 back and I know that it's stolen because someone watched Youtube videos and deleted them from my history. Security at my h.s. Said that on the same day someone else lost an iPhone, it was sold thrice. So I'm not sure of my chances of finding it, but it has my Gmail and my things, et cetera. I'm sure that it's not going to travel so far away from my city. Wherever it is, I'm determined to get it back.

Did you ever add anti-virus protection? If you have LOOKOUT or AVAST or most of the protection apps have tracking built in. You have to go to their website. Some programs allow you to erase your personal info and passwords. If you did not add a protection program your out of luck

Report it to the police and to your phone company.

Call the carrier to help track the phone.
