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)
Bus	BUS 123	BUS	all
Dealer	DLR 123	DLR
Government of Guam	1234	none
