USPS

How do I get the USPS tracking number for a sports card I mailed.  I only have the eBay tracking number and the post office can look that up.

You must have used the eBay Standard Envelope to ship the card.  This service does not have the normal tracking information.  

To track the item you need to enter the tracking number into   https://www.trackmyshipment.co/

This should show your item.
