General plates

Starting in the 1950s, WA released the U series plates, which commenced in a six character white-on-black design and changed during their release to be of an inverted black-on-white design as would be seen continued in the release of the X-series plates. The letters "Q" and "V" were not issued in any combinations, due to these being easily mistaken for "O" or "0" and "U", "Q" was only used by Government of Western Australia departments. The X-series and U-series plates are now available again by request, as "retro" plates in either black-on-white, or white-on-black. UQB·nnn was reserved for Transperth buses with three-digit registration numbers usually corresponding to the bus fleet numbers. Since June 1990, Transperth buses have been issued green on white plates in the TP·nnnn range. Other government vehicles also used "Q" as the second character until the new series in 1997.
In October 1978, having exhausted the XAA – XZZ series a new series was released commencing at 6AA·000. The format used was black on yellow, where the numbers preceding the letters ranged between 6 and 9. This series ended at 9MZ·999 and the trailer series ended at 9RZ·999. As of February 2025, The Department of Transport has now reintroduced the old 6,7,8 & 9 series marketed as Nostalgia Series https://plateswa.com/#/choose-your-style/nostalgia
The current standard issue series is blue on white, with an extra letter added to create a seven character registration plate standard. Introduced in September 1997, it commenced with the characters 1AAA·000, estimated at the time to reach 1ZZZ·999 in 2137. The "1F" allocation has been reserved for silver-on-black slimline plates, sold as platinum plates that were first issued in May 2016. As at November 2025, the "1FDC-000" sequence was being issued.
Government issued vehicles use the "1Q" series, with inverted colours.
New car dealerships use the “1ZZ” series for new, pre-registered vehicles.
Hire vehicles can use the "1Y" series, but is not compulsory.
Privately owned buses or designated school buses use the current series.

Stock Carrying Trucks have 'ST' as the second & third letters of the prefix; e.g., 6ST·123, 9ST·123, 1STA·123.
Trailers, caravans etc. have 1Taa·nnn or 1Uaa·nnn. Earlier series used 'R', 'S', 'T', 'U', 'W' and 'X' as the second character for trailers. Country Shire/Town trailer plates follow the normal shire prefix system, but only one plate is issued, some shires have a block of numbers for trailers, others issue the next available number.

Outside metropolitan Perth

There are 143 registration districts which each issue number plates using the form "loc·n" and "loc n" – for example, "A nnnn" would be a plate issued by the City of Albany, while "AU·nnnn" would be issued by the Shire of Augusta-Margaret River. A full list has been published near the back of the government-produced Metropolitan Street Directory/''Streetsmart'' each year since 1985. Special number plate versions for shires, cities and towns have been made available to purchase. They are in the format "nnn*loc" with the shire-, city- or town-crest between the numbers and letters.
In recent years towns within shires have been allocated number plates. Examples include "FR·nnn" for Frankland in Shire of Cranbrook and "KND·nnn" for Kendenup in the Shire of Plantagenet.
