{{expand}}'''Halo numbers''' are the numbers assigned to pieces of the NIN discography in the order that they are released, so that a collection can be neatly ordered, supplied, and bragged about.Halo numbers are sometimes modified for variations of a release, such as the different versions of ''The Downward Spiral''. Some Halo numbers are shared with promotional items; Halo 10 is shared with the "Hurt" and "Piggy" promo CDs and Halo 16 is shared with the "Into The Void" promo CD.

===Seeds===
Promotional Seed numbers are used to catalog promotional releases that come directly from NIN, in a similar manner to the Halo numbers. The bootleg three-disc "Definitive NIN" collection was released via BitTorrent by the user ''Seed0'', who also uploaded the ''[[Broken Movie]]'' and ''[[Closure]]'' DVDs. It is believed that the bandwas behind this release as well.
