Is the flash code a receiving code?

There will be a pick-up code when picking up goods by flash delivery, and a receiving code after delivery to customers. So the flash code is not necessarily the receiving code, but also the picking code. Flash code fetching and receiving are different, because they are sent to the sender and receiver respectively.

"Flash delivery" service is a project of Bing in the same city, which is committed to providing users with direct delivery by special personnel and monitoring services throughout the whole process.
