How to get a tracking number 
Check your email for your shipping confirmation. 
Whenever you make an online purchase, getting a tracking number is as easy as keeping an eye on your inbox. In most cases, you'll receive an email saying that your package has been shipped within 1-3 days.
If you haven't received a shipping confirmation within 3 days, message the seller and ask them to confirm that it's been scheduled for delivery. Be sure to dig through your spam and trash folders, as well.
