Security guarantee for express companies. From the perspective of express enterprises, considering safety factors, they are more in favor of real-name system than ordinary citizens. Tan Guangjin, manager of Liwan Huanghe site of YTO Guangdong branch, said that if the real-name system for express delivery was implemented, the workload and cost of express employees would definitely increase. "But I personally think that the courier real-name system is good objectively. It is a security guarantee for express companies. If there is a problem, it can be traced to a specific person." Zhang Jun, manager of Yunda Haizhu District No.2 company in Guangzhou, Guangdong, also believed that the implementation of the real-name system for express delivery is a good way to ensure safety. Reporters learned from many express companies that the real-name system for express delivery has not been mandatory in Guangzhou so far. Relevant persons in charge of Guangdong Express Association also said that they have not received notice of the implementation of the real-name system. At present, EMS, a state-owned enterprise, has not implemented the real-name system either. The customer service personnel of EMS No.407 told reporters that it is not necessary to provide ID card or register number when sending express parcels through post office now, but all the items to be sent must be checked by the staff after opening the box, which has been implemented in this way all along. Relevant persons in charge of the "Problem Department" of YTO Guangdong Company also said that couriers will open boxes to check goods. "After opening the box to check the goods to ensure the safety of the items being sent."
