This table provides a view of the passenger plate numbering formats on the various bases through the years. At this time it is not intended to be a comprehensive listing – it’s a work in progress. Several of the ‘oddball’ formats used for only short periods of time are not included in order to keep this table to a reasonable size. Clickable images will be added at a later time. Generally, the oldest plate in any given format is the original and ones below it are either a continuation of the series or more often remakes of old numbers on new bases.
