Do I have to register package in advance?

No need!
KorGou transhipped to reduce the burden of users, eliminating the flow of forced parcel prediction, replacing KorGou staff with careful inspection and sorting when the package arrives.
Each user will automatically assign a unique Korean transhipment address with a unique user code to the system after registering at com. Users can simply follow the system when ordering on a shopping website. The package will be automatically identified and fed into the KorGou repository when it arrives.
In part, the package arrives at the warehouse due to a lack of identification information due to a user’s error in filling in the message received on the shopping site, or when the document pollution is broken or lost. The package will be classified as a unidentified package. In this case, we return the package to the seller or  the user can provide the corresponding information in the system to claim the package, and the KorGou staff will manually confirm the package’s ownership and then process it for warehousing.
KORGOU takes a little extra effort to save the user’s mind.

不需要！

KorGou转运为用户减负，取消了强制包裹预报这一流程，代之于让KorGou工作人员在包裹到达时仔细检查和分类入库。
每位用户在KorGou.com注册后系统会自动分配一个带有唯一用户编码的韩国转运地址，用户在购物网站下单时，只要按照系统的教程正确填写了收件信息，包裹到达KorGou仓库时便会自动识别并入库。
部分情况下，由于用户在购物网站上收件信息填写错误，或者运单污染破损或丢失时，包裹到达仓库时由于缺少识别信息导致无法入库，将有可能被退回给卖家或者该件包裹会被归类为疑难包裹，在这种情况下，用户可以在系统里提供相应的信息认领该包裹，KorGou工作人员会手工确认包裹归属后作入库处理。
KorGou多费一点心，用户就能省一份心。
