Can it be scanned in just like the bar code on the bottom?
There are 3 different intelligent mail barcodes on the label (or 1 or 2, depending where you purchase the label).
The one on the top can be square or rectangular or non-existent, depending where label is purchased.
The tiny square one by the address and duplicated at the bottom under the large barcode (it's often referred to by some as a QR code, but technically it's not) was added by USPS about a year ago and you can read more about it here. According to that linked news article, "If an employee or piece of equipment is not able to scan the regular barcode, the Intelligent Mail matrix barcode can be scanned instead."
The large traditional barcode on the bottom can be scanned by everything: sorting machinery, the post office, handheld scanners, self service kiosk.
None of them are QR codes - they are all intelligent mail barcodes.
The QR code generated when a seller purchases a label online is different. The QR code can be scanned by the post office, or scanned at the self service kiosk, to have a label printed by USPS. The QR code itself is never printed on a label.
