What is the model number of macbook pro 2020

I want to buy the new m1 macbook pro. The model number on all websites starts with MYD82xx. However on apple‘s website its MYD83xx so why is it different? All the other 3 model numbers are identical with other models except for the space gray 256 gb above.
