Concerned About Stanley Thermos Authenticity and Lifetime Warranty After Registration

I recently registered my Stanley thermos for a lifetime warranty. After filling out the form, I received a confirmation email stating the registration was "successful." However, to test the process, I entered "111111" in the barcode section and still received the same "successful" email. Now, I’m unsure if my product is authentic and if it truly has a lifetime warranty. If the system confirms every entry as successful, how can I verify that my thermos is genuine and covered by the warranty? I need clarity on this process to ensure my product is properly registered and authentic.
