How to tell the true from the false? Bank of China Nikon 8 10

I started from d8 10 in Taobao, and the four codes were integrated. I checked that it belongs to China Bank, and I was relieved after using it for half a year. Recently, I found a post saying that this method can be used to identify the running water of Nikon cameras, as shown below. The post said that the last eight digits of this code in the licensed box should be the same as the production date of the battery. I also asked my friends who bought them in physical stores, and they were all the same. I don't know whether my camera is licensed or parallel. I checked the battery and charger and found nothing wrong. There is small print next to the battery contact, and the charger is the same as my friend's original one. The ticket was issued after the ticket inspection, and the merchant did not upload it. The merchant said that it would not affect the warranty. Although the camera has been carefully checked, there is no suspicion of second-hand, and there is a fresh smell of new products when it is unpacked, I still want to know whether all licensed cameras have the last eight digits of the code in this box consistent with the production date of the battery. Can it really be judged that it is running water? Some friends are licensed in physical stores, but are these two codes inconsistent?
