Not exactly sure what you are referring to in terms of the product numbers for the Samsung 860 EVO drives.
The 2TB and 4TB models don't even mention a specific product number on the support list. And for the 250GB (MZ-76E250) and 1TB (MZ-76E1T0) models, as far as I can tell, these drives are still being sold at many retailers online.
Note that you may see a few additional letters appended to the end of the product number like BW or B/AM or E (for example, MZ-76E1T0BW or MZ-76E1T0E). These additional letters are merely used to designate different packaging and warranty regions for the drive, they don't actually designate a difference in the actual drive model hardware. The label on the back of the drive will show the model number MZ-76E1T0 without any additional letters.
The BW code means the drive ships in a retail box with worldwide warranty, B/AM means retail box for the Americas region, E means an OEM (usually white box) drive which may come without a warranty. This isn't a complete list though, there are a handful of different region or packaging-specific letter codes that Samsung uses.
