Hi Emelya_147,

Please note that product registration mainly helps with warranty. You can find your activation code on the scratch card inside the packaging as indicated here. If the card is missing or the code was already used, please contact the reseller about a replacement. Also, make sure to buy Razer products from authorized Razer resellers to be sure you’re getting a genuine device. Products bought from non-authorized dealers can be used, counterfeit, re-boxed, defective, or gray market goods. 

Kindly note that Razer Insider doesn't have support for your preferred language. Please post your inquiry or concern in English across all boards. All the best!
