The postman called by express for the verification code.

What you're asking is that it's normal for a postal courier to call for a verification code? This behavior is normal in the express delivery industry.

According to the official postal information, the postal courier needs the verification code of the recipient to better verify whether the identity of the recipient is true, which is to ensure the safety of the courier and the interests of customers. Postal couriers will take some measures to ensure the delivery and receipt of express delivery. Among them, verification code is a common measure.

If you receive a call from the courier asking for a verification code, you need to provide the correct verification code to receive the courier. If you are not sure whether the verification code is correct, you can contact the sender for confirmation.
