From Territory Plates to the Rainbow
More than a century of island registration history — from county-issued territorial plates to Aloha, King Kamehameha, the Hawaiian warrior and one of America’s most recognizable modern plates.
Plate Evolution
Six representative eras across Hawaii registration history.
Hawaii Before Statehood
Hawaii had license plates decades before it became a state. After becoming a U.S. territory in 1898, Hawaii motor vehicle registration began in the early 1900s. Hawaii did not become the 50th state until August 21, 1959, so early Hawaii plates are technically territorial license plates.
Because the islands had no inter-island roads, early registration was handled by individual county governments (Honolulu, Hawaii, Maui, and Kauai) rather than a single statewide department. Early tags featured county designations and territorial legends like TER. HAWAII or T.H. stamped into metal.
You Can Tell Which Island a Hawaii Plate Came From
Hawaii passenger serials have historically been county-coded, allowing spotters to identify the island of origin from the serial prefix.
Hawaiʻi County
The Big Island
Hawaiʻi County has historically used H, and later Z, prefixes.
Kauaʻi County
Kauaʻi
K is directly associated with Kauaʻi registrations.
Maui County
Maui, Molokaʻi & Lānaʻi
Maui County has historically used M and later L.
Honolulu County
Oʻahu
Honolulu uses most remaining letter series rather than one single permanent letter.
Spotter Note: Letters I, O, and Q are avoided in passenger serials to prevent confusion with numbers 1 and 0.
The First “Aloha” Plate — 1957
In 1957, while Hawaii was still a U.S. territory, Hawaii introduced ALOHA on its standard passenger plate. The design featured white characters on a red background, with ALOHA at top and HAWAII at the bottom.
“ALOHA appeared on Hawaii plates before Hawaii was even a state.”
This red plate was a major milestone: Hawaii was already branding itself with “Aloha” two years before statehood.
Hawaii Becomes the 50th State
Hawaii entered the Union as the 50th state on August 21, 1959. Importantly, the existing 1957 ALOHA base remained in use through 1960. The plate didn’t immediately change when Hawaii became a state.
“Aloha State” — 1961
In 1961, Hawaii replaced the shorter ALOHA slogan with ALOHA STATE, which has remained on standard passenger plates ever since.
The 1961–1968 design featured white embossed characters on a dark green background, with HAWAII at top and ALOHA STATE at the bottom, celebrating Hawaii’s official state nickname adopted at statehood.
Yellow Aloha State — 1969–1975
In 1969, Hawaii switched to black characters on reflective yellow, keeping HAWAII at the top and ALOHA STATE below.
The design remained clean and typography-focused, which made the artistic shift of the subsequent 1976 issue especially dramatic.
1976: King Kamehameha, Diamond Head & Hibiscus
In 1976, Hawaii introduced a dramatically different scenic plate.
King Kamehameha I
Honored the Hawaiian monarch who unified the Hawaiian Islands into a single kingdom in the early 19th century.
Diamond Head
Featured the recognizable volcanic tuff cone (Lēʻahi) overlooking Waikīkī.
Hibiscus
Celebrated native island flora alongside scenic blue and red lettering on a white/pink-toned field.
The Hawaiian Warrior Plate — 1981–1990
In 1981, Hawaii replaced the scenic design with a reflective white background, brown characters, and an orange Hawaiian warrior head graphic.
This design also marked the adoption of the modern ABC 123 serial structure, with county coding embedded in the first letter.
1991: The Rainbow
In 1991, Hawaii introduced the standard plate design that would define the state for more than three decades.
Why Is There a Rainbow on the Hawaii License Plate?
Hawaii features a rainbow because the islands’ combination of sunshine, ocean moisture, trade winds, and localized showers creates frequent rainbow conditions. Rainbows also have cultural significance in Hawaiian tradition. Since 1991, the rainbow has become an instantly recognizable visual shorthand for Hawaii.
A Plate That Lasted More Than 30 Years
While many states repeatedly redesigned their plates, Hawaii kept essentially the same visual identity. Like Vermont’s green plate or Oregon’s Douglas fir, the combination of Rainbow + Aloha State became permanent parts of state identity.

Can You Tell Which Island It’s From?
Spotter Shorthand: Serial allocations have evolved over 30+ years, so treat this as a practical spotting shorthand rather than an unbroken rule.
