please provide me the tracking information of my package, the tracking number is RL900711858CH

1. This is what I get when I try to track your number on the Swiss Post:
RL900711858CH
Unfortunately your search was unsuccessful. The causes of this could be:
- Consignment has not yet been handed over to Swiss Post or scanned.

2. May I suggest you contact sender of the parcel to find out if he did Physically mail the parcel.

Hope this help.

As it ends with CH you should look into swiss post tracking, check out "trackingmore".
There's no other info at the moment on the tracking.
