why cant i use find my iphone app my iphone was stolen

Hello deshaunpettway,

Welcome to the Apple Support Communities!

I understand that you no longer have your iPhone and are trying to use the Find My iPhone application to use it. I am not sure of your specific situation, but if you provide more details on how you are trying to locate your iPhone and/or use the Find My iPhone application it would be helpful. I would still; however, recommend reading over the information in the attached article to help you locate your iPhone.

If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support

Have a great day,

Joe
