'' from July 2018, the MPC announced that changes in their data processing pipeline will enable numberings to occur more frequently. It is stated that the new method will clear the backlog of unnumbered minor planets with an already well-established orbit without changing the criteria for numbering. Previously, this was not possible because of the difficulty of determining who was the discoverer. Despite this announcement, however, the total of unnumbered minor planets has since rather than decreased.

1994–2004

2005–present

The year of principal

for most unnumbered minor planets is younger than 2004 (''see ''). They are not listed in any of the partial lists due to their large number and frequent changes. New partial lists may be created in the future, as additional observations ultimately lead to new numberings and to fewer unnumbered bodies.
