Hi @I14, I am terribly sorry to hear about this.
It is not possible for us to trace the whereabouts of your phone using the phones IMEI number. You can however use Googles service Find My Device in to see where your phone is located. Simply log in to the service using your Google credentials and Find my device will pinpoint the location where the phone is located/its last known location provided that the phone is or have been turned on and connected to a mobile network.
I hope that helped. Let me know if you have further questions!
