Merchants should pay attention to the dialing method when they can call the "virtual number" through the customer order information to contact customers.
For example, if the virtual number is "13049828540 to 5 109", you can dial the first half of 13049828540, and then enter "5 109" after hearing the prompt "Please enter the extension number".
When merchants and riders dial the user's phone, the incoming number displayed on the user's mobile phone is also a "virtual number", that is, 1 1 digit mobile phone number, so that when the user calls back to the merchant, the "number protection" function can still be turned on, and the information security of the user and the merchant can be ensured in both directions.
However, it should be noted that three hours after the order is completed, the virtual number displayed by the merchant will automatically disappear and become the real number of the user who hides the middle four digits.
