JD.COM can't give something without picking up the code?

JD.COM can't give anything without the pick-up code. The reason for signing the code is mainly to determine whether it is the owner of the package, that is to say, a verification code will be sent to you before receiving the goods. The pick-up code means that you can use this pick-up code to get the goods you bought, and the receipt means that the courier company has safely handed over the residents.
