Need to get a number from my phone without having my phone. Possible?

I left my phone at a friends house but they are not home so I can't just go get it. Is there a way to use find my iphone to get their contact out of it so I can call them from another phone and tell them its t their house?

Hopeless.

Just wait until someone is home.

No, but you can check you contacts online on your iCloud account.
