This is a partial [[list of unnumbered minor planets]] for principal [[Minor planet provisional designation|provisional designations]] assigned during 1–15 September 2004. Since this period yielded a high number of provisional discoveries, it is further split into several standalone pages. {{Asof|2025|11}}, a total of '''143''' bodies remain unnumbered for this period. Objects for this year are listed on the following pages: [[List of unnumbered minor planets: 2004 A–B|A–B]] · [[List of unnumbered minor planets: 2004 C|C]] · [[List of unnumbered minor planets: 2004 D–E|D–E]] · [[List of unnumbered minor planets: 2004 F|F]] · [[List of unnumbered minor planets: 2004 G–H|G–H]] · [[List of unnumbered minor planets: 2004 J–O|J–O]] · [[List of unnumbered minor planets: 2004 P–Q|P–Q]] · '''Ri''' · [[List of unnumbered minor planets: 2004 R (200–299)|Rii]] · [[List of unnumbered minor planets: 2004 R (300–619)|Riii]] · [[List of unnumbered minor planets: 2004 S|S]] · [[List of unnumbered minor planets: 2004 T (0–99)|Ti]] · [[List of unnumbered minor planets: 2004 T (100–199)|Tii]] · [[List of unnumbered minor planets: 2004 T (200–299)|Tiii]] · [[List of unnumbered minor planets: 2004 T (300–619)|Tiv]] · [[List of unnumbered minor planets: 2004 U–V|U–V]] · [[List of unnumbered minor planets: 2004 W–X|W–X]] and [[List of unnumbered minor planets: 2004 Y|Y]].
