Why doesn't ems answer the code?

Ems didn't take the code because the goods haven't been put into storage yet. According to the relevant information, the goods have just arrived at the station and have not been put into storage, so the delivery code will not be issued. Therefore, ems has no delivery code because it has not been put into storage, and there is a delivery code when the goods are delivered to the express cabinet. Ems is a postal express service and an international mail express service managed by the Commonwealth.
