Onekey hardware wallet

Hello guys. I have a question. I just recieved my package with the hardware wallet. I noticed that the order number on the package is different from the order number that I received before delivery in my e-mail. Is this normal and legit? I want to make sure my package has not been tampered with. The order number that I received before delivery in my e-mail consisted of 5 numbers. While the order number on the delivered package consists of 6 letters and 6 numbers.

Thanks!
