If you had Find My iPhone turned on just use any computer and go to icloud.com and sign in then select Find iPhone. If you are satisfied, please kindly provide an OK or Above Rating - so I get paid. Keep in mind you can always come back to this page at any time regarding this question. Thanks!!
Well you have to do that to find it. Did you forget your Apple ID or Password?
If it is a work controlled iPhone then you have to ask your IT dept to help you...
