Mail and Priority Mail ship methods are not trackable.
Some shippers provide tracking numbers that help ensure the safe arrival of your package. Packages with tracking numbers are scanned at each checkpoint on their journey, allowing the packages to be tracked as they move through the shippers system to their destination. If an issue arises with a package the location is readily identified and makes the chances of recovery more likely. If tracking data does not show for your order, and the estimated ship time has not yet passed, there is no need to panic. In times of high package volume a shipment won't be scanned until it reaches a regional hub near the destination.
Here is a handy tool for tracking your delivery - no matter the shipping agency. Simply click on this link http://ltracker.herokuapp.com/ and enter the tracking number. The tool will determine the shipper based on the number and display the tracking page for your package.
Some shippers only offer Delivery Confirmation numbers. Delivery Confirmation gives the date, zip code and the time the package was delivered. If delivery was attempted, the date and time of attempted delivery will be given. There is no capability to determine where your package is at a given time in its movement to you. Packages with Delivery Confirmation do not get scanned at each checkpoint on their journey like a tracking number, making it impossible to locate a package that may have gone astray.
