There is no express delivery at the rookie station, but there is a pick-up code.

If you receive the pick-up code at the rookie station, but you can't find the corresponding courier, there may be the following reasons:

1. The courier lost the express mail during delivery, resulting in only the pick-up code and no express delivery.

2. The courier was taken away by others, leaving the pick-up code, but there is no corresponding courier.

3. There was an error in the system, which caused it to be recognized as someone else's number when it was put into storage, and the delivery code was sent to you.

Relatives and friends sent you a courier without telling you.

If you want to confirm the specific reason, you can contact the staff of the rookie station and provide the pick-up code and express delivery number (if any) for inquiry.
