On the day that your order is ready to ship, we assign the UPS tracking number. Until UPS scans that number and loads your project into the truck, it will show up as invalid.
If you attempt to track your order, try it after 8pm ET or the following business day for best results.
You can track a UPS package here - https://www.ups.com/track?loc=en_US&requester=ST/
Please note if this is for an international address, your tracking number will be with UPS.
