A PS2 contains two unique identifiers on its rear sticker. A number labeled "SERIAL" to the left, and a barcode sticker offset to the right, with different characters in each.
This random PS2 from an internet screenshot has a "serial" of "AU43211911", and a "barcode" of "PX443219113".
If I am cataloging a PS2 for asset tracking, collecting, grading, or any other purpose, which of these numbers would I use to represent its identity and why?
