USPS does still have a record of that but it is archived.
You will have to open a case with USPS to retrieve that information.

This is one advantage of using stamps.com or one of their subsidiaries.
The tracking information stays in the software for a period of 2 years.

USPS’ 1-800 can not help you but you can get the info from any post office. For some reason, the computer systems are different and the one at the PO stores the info longer. The computer system used at the 1-800 customer service is the same info we can see using usps.com. Hope this helps!
