1 The seller did not deliver the goods, but only filled in the single number.
2. The seller has delivered the goods, and the logistics company has received many pieces and is still waiting for scanning.
3 Express delivery In order to be convenient and quick, the express delivery form will generally be provided to the merchants to fill in in advance, so that the merchants can confirm a express delivery form for you after confirming the order. At this point, the goods you bought are likely to have been packaged and posted by courier, waiting for the courier to pick them up. Merchants just enter the single number into the delivery system in advance, and you can find the single number, but there is no record. This situation is more common.
4 False delivery, because some merchants are temporarily out of stock, in order to avoid customers' reminders and don't want to lose this business, you can click delivery in advance and enter the single number. Then wait for the new goods to arrive before delivery, which often leads to more serious delay in receiving goods.
There will be a delay in network display, and logistics information will be posted online in about half a day.
