Vehicle registration plates of the United States for 1901
At this early point in the history of license plates in the United States of America, none of the 45 states, territories, or the District of Columbia, was issuing its own plates. In this year New York became the first state to require vehicle owners to register their vehicles. The owners of these early New York vehicles had to provide their own license plates with only their initials on them. Plates were often made of metal letters on a thick leather background or on a steel base. This system of using  the owners initials lasted until 1903 when a change to using a number provided by the state began. While New York may have been the first state to require license plates for their vehicles, there were already cities that required plates. The city of Chicago passed an ordinance in 1899 that required their owners to pass a health test, an oral test, demonstrate their capability to operate the type of vehicle they owned, such as gasoline, steam, or electric, and mandated that the owners place a registration number issued by the city on the back of their vehicle. While this  Chicago ordinance took effect in 1899, the first tests were not held until February 17, 1900. Passenger baseplates.

These early license plates were created from kits that could be purchased at a hardware store, may have been available from  automobile clubs or associations, they were forged by blacksmiths or other tradesmen, or the owner may have made their own plate with whatever materials they had on hand. Prestate plates were made from a variety of materials, but most often were made of leather, steel, or wood. The prestate era officially ended in 1918 when the state of Florida began to officially issue license plates. State registrations.
