My Android 6 TECNO N2S was just stolen. How can i be helped about the Serial Number I don't know?

[Android Central Question]

On stealing my phone, I visited a phone tracker. He's asking for the Serial Number of my Android device. I don't know it and i am not also having the box in which the phone came along.
How do i go as per this issue is concerned?
