[quote name='htz']The correct one is the one on the left. Not the one on the right that says "serial no.".
P.S. You can't register 2 vitas, its against the promotional terms. You might be able to bypass it with 2 unique PSN IDs but no guarantees.[/QUOTE]
Thanks for the answer, but it says that number is invalid. And when you click on the "Where can I find my Serial#?" link it recognizes the one on the right as the serial, but that one doesn't work unless an extra digit is added.
