Null numbers are the numbers assigned to pieces of the Trent Reznor and Atticus Ross discography in the order that they are released, in the style of Nine Inch Nails' "Halo numbers". They are so named because they are released or published via The Null Corporation. The assignment and order of the numbers was confirmed by John Crawford on Echoing The Sound forum and Discordance.
