People in Guangdong province are to be asked for ID cards when sending or accepting express deliveries, to clamp down on illegal and dangerous packages in the mail.

The move will be piloted in Huizhou and Zhuhai by the end of the year, according to Guangdong Provincial Public Security Department.

"The real-name (requirement) for express delivery will cover the entire province next year," senior drug enforcement officer Wang Yukai told local media.
