Can I reply to China Post Express SMS?

If it's about the account number of China Post Express Easy Bank Card, you can reply. If you receive a short message about a package from China Post, you generally don't need to reply.

According to the regulations of the State Post, before delivery, the courier should send a short message with the contents of "courier name, courier number, courier name and courier phone number". When the recipient receives this short message, he can check whether the courier number is from the goods he bought.
