The tracking number will be provided in an email confirming the shipment.
I have been sending packages all over the world for 3 years. I have never had a lost package to date (even with the Covid-19 crisis). They sometimes took a long time to arrive or return, but the customer or I received it in the end.
Contact me for a follow-up, a claim with the postal services, or an amicable arrangement if ever the package was lost, stolen, or arrived in bad condition.
