Uber eats has a pin code list of its own.
There are two reasons for this
1. If the customer has reported that he/she has not received any meal, the system will automatically change his/her order to a pin code order, and if the customer feels disturbed, he/she can cancel the pin code order by himself/herself by reporting to the system.
Basically, 70% of the reasons are that the guests do not want to go downstairs to return to the platform.The first is that his food was mistakenly taken by a resident of the same building, the second is that the delivery person left it in a place where the customer couldn't find it and the third is that the customer was targeted for cheating on his food.
2. The single is McDonald's Happy Delivery, pin code that is fixed for the guest cell phone after four codes, Happy Delivery of the single can not skip the pin code, if the guest can not find the pin code will have to send the single back to McDonald's.

This is the pin code list, just ask the customer for the four digits and reply.
However, there are always some very special conditions, such as ordering guests drink hang up, pin code forgotten, or forget to give, various different reasons will need to skip the pin code, the following is the description of the steps.

Click on ”I need help.”

Select the reason for not receiving the pin code.

Finally, press to complete the delivery.
Although the delivery dough itself is a deliveryman who will go upstairs, but that's only because I want to lose weight on the way, unless the phone does not answer, and the message is not returned, then I can only put it on the first floor.
But in fact, I went upstairs the chance is definitely not 100%, the beginning of at least 20% of the chance is that I simply can not find the customer's door, call and ask the customer to ask the customer to ask the customer to come down to get their own, and now the chance of having slowly reduced but has not yet returned to 0 over.
Some times to deliver some bad delivery and forced upstairs single I will still use to this, although my way of dealing with the customer's home door, did not come out to meet me, then directly put the floor on the ground, pin code to press the skip to leave.
The pin code is not omnipotent. A delivery that will go upstairs is one that will go upstairs, just like a customer who will not go downstairs is one that will not go downstairs. Although the percentage of delivery that will not go upstairs is only less than 10%, the number of customers who will not go downstairs is definitely more than 10%, and the number of Panda customers can be as high as 30%.
