Due to the loss or delivery error of important items such as ID cards, it may lead to serious consequences. Therefore, when sending an ID card, it is recommended to inform the courier and take some extra measures to improve the security of the package.

Specifically, you can take the following measures:

1. Tell the courier that the ID card is in the parcel, and ask the courier to pay special attention and handle the parcel carefully.

2. Use strong packaging materials, such as envelopes or bags, to ensure that the ID card will not be damaged during transportation.

Mark the words "ID card inside" on the parcel so that both the courier and the consignee can notice the importance of the parcel and handle it carefully.

In addition, for particularly important documents, it is recommended to choose more reliable courier services such as EMS or SF Express to reduce the risk of loss.
