No, I'm in the U.S. so I was thinking it may work in a similar manner in Canada. Here it's 4PX-->DHL-->USPS, so IF you received a 4PX tracking # from Giantoy for you it might be 4PX-->UBI Smart Parcel-->Canada Post.Are you in Canada? Do all of OSK tracking become available on Canada post? Will it be the same tracking number osk initially provides
I don't know how it works in Canada but USPS doesn't recognize the 4PX number. Once it's turned over to DHL I can see all 3 tracking numbers (4PX, DHL and USPS) via DHL tracking. The DHL # is like 30 characters long, the last 22 being the USPS #. UBI Smart Parcel tracking may give you similar details.
