Can I register two i phones in one account

Hi.I'm Hyeonwoo Eric Jeong. I was stolen my i phone about a month ago. I had tried to find my phone but it was hard to find, so I ordered new i phone lately. Though I bought my new i phone, I want to keep track old one which i was stolen. So, my question is, Is it possible that register new i phone in my account and Find my i phone app without delete old one?
