Vehicle registration plates of Guam

The U.S. unincorporated territory of Guam first required its residents to register their motor vehicles and display license plates in 1916.^[1]

In 1956, the U.S. states and Canadian provinces came to an agreement with the American Association of Motor Vehicle Administrators, the Automobile Manufacturers Association and the National Safety Council that standardized the size for license plates for vehicles (except those for motorcycles) at 6 inches (15 cm) in height by 12 inches (30 cm) in width, with standardized mounting holes.^[2] Guam adopted these standards in 1960.

Baseplates 1953 to present

Since 1996, all passenger plates have featured a round mounting hole at the top right and horizontal slots in the other three corners, as with plates of Hawaii and the Northern Marianas.

Coding

Non-passenger

On the 1994 base, commercial truck plates were coded by location of issuance, but using a different geographical coding system than for passenger plates. These codes were based on more specific geographical areas or geographical features, rather than political jurisdictions.

Bus, dealer, taxi, and trailer plates were coded only by type, not location of issuance.

Type	Serial format	Code	Location
Commercial Truck	1234ABC (variable number of digits preceding letters)	FAP	Fort Apugan (Hagåtña)
		FSO	Fort Soledad, Umatac
		MLL	Mount Lamlam
		PDE	Plaza de España (Hagåtña)
		TFL	Talofofo Falls, Talofofo
		TLP	Two Lovers Point (Tumon)

Dealer	DLR 123	DLR
