NES model numbers: which one do you have?
Where the model number is
Turn the console over: the model number is on the label underneath, usually next to the serial number.
How to read it
NES consoles read NES-001 (the original front loader) or NES-101 (the 1993 top loader). Other NES- codes are accessories.
