I cannot, since I can't collect personal information on the site.
However, the Samsung customer service center would be able to help you out. If you're in the U.S., the number is 800-SAMSUNG. If you're in a different region, you'd be able to contact Samsung at the customer service center on the Support site of the Samsung.com webpage in your region.
I'm trying to register my device however the samsung site is not accepting the serial number from my phone. Can you assist?
