What is the final destination country of this tracking number, RS668039638CN?

Since the first one from Bernie, USA, Aug. 03, 2017 14:40, still there is no way of any progress on this tracking.
Now, the question is where is the destination of this package? My guess is that the last 2 letters, ---CN, indicate the destination is Canada. Is it correct?
The package should be headed for US.
Please advise ASAP.
