[3] Similar to other reissue labels such as Rhino, Bear Family, Ace, Cherry Red, and Hip-O, Numero releases feature extensive liner notes and rare photographs that provide context for the associated recordings.

[4] For Record Store Day 2009, the Numero group produced a vinyl-only sampler named This LP Crashes Hard Drives, which included not only a track from an upcoming Numero release ("Sam" from 029 Pisces: A Lovely Sight), but also tracks from such labels as Light In The Attic, Honest Jon's, Now Again, Sublime Frequencies, Daptone Records, Jazzman, and Vampisoul.

"You And Me" by Penny & The Quarters, which was featured on 2007's Eccentric Soul: The Prix Label compilation, was used in the 2010 film Blue Valentine.

During the film's theatrical run, the identity of Penny & The Quarters was unknown and the Numero Group was actively seeking contact with band members or their relatives.
