| First issued | 1910 |
| Last issued | December 31, 1978 |
The former U.S. territory of the Canal Zone first issued license plates in 1910, and this continued until September 1979. (The 1979 plate was the 1978 plate with a 1979 decal affixed.)[1] A single plate was issued for all years. The country of Panama also issued license plates identifying United States citizens that lived in Panama but worked in the Canal Zone, but these plates have the country name "Panama" clearly showing on them.[2] Since reciprocity for license plates between the Canal Zone and Panama did not exist until 1950, old photos often show local vehicles with two different license plates mounted on the vehicle.[3]
1910 to 1955
1956 to 1979
In 1956, the United States, Canada and Mexico 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.[4]

Non-passenger plates
Miniature automobile license plate

Miniature automobile license plates were included in boxes of Wheaties cereal in 1953, and they are oftentimes called bicycle license plates. Included in one of the sets issued by General Mills was a Canal Zone license plate. Other plates in this set included the following locations: Alaska, District of Columbia, Dominican Republic, Guam, Hawaii, Italy-Military, Philippines, Virgin Islands, and the Maharajah plate with a golden double headed eagle.[6] Note that all of the license plates issued for each state, province, territory, or country had the same serial number (Canal Zone plates all have the W3966 serial number).
