How to synchronize Pinduoduo's private number to the last one?

Open Pinduoduo APP, click Personal Center, click Settings on the Settings page, and click Privacy Number Protection Settings. Just turn on the switch next to number protection.

The theme of today's course is the buyer's privacy protection service guide. I think everyone found it. When the buyer places an order, we click to check the phone number of the buyer. Now many of them have become private numbers. What is a private number? Simply put, the platform is to protect the private information of buyers. When the merchant checks the mobile phone number in the order, the platform will replace the buyer's real mobile phone number with the privacy number. Then this number can contact the buyer normally and deliver the package with the privacy number. Buyers can also receive SMS reminders normally, which will not affect normal delivery. If the package is put into the express cabinet, postal collection point, etc. , receiving information and SMS will be forwarded to the buyer in real time. There are two main uses of the privacy number: the first is to contact the buyer, the merchant or courier directly dials the privacy number, and after hearing the voice prompt, enter the 4-digit extension number behind the recipient's name or address to connect the buyer. Then this extension number has two specific display positions. The first one is a receipt. The second is that the shipper can directly use the privacy number to deliver the goods, and copy the complete recipient's name and address when filling in the receiving information. When we copy the four digits in brackets, all the information must be copied completely and cannot be omitted, otherwise the normal delivery will not be possible. In the process of using this privacy number, what should I do if the buyer reports that he has not received the SMS reminder? If we use the privacy number to deliver the goods, we can let the buyer go to Pinduoduo app- Order Logistics Details page.
