The world's first parking meter is installed in Oklahoma City, Oklahoma.

A parking meter is a device used to collect money in exchange for the right to park a vehicle in a particular place for a limited amount of time. Parking meters can be used by municipalities as a tool for enforcing their integrated on-street parking policy, usually related to their traffic and mobility management policies, but are also used for revenue.

Oklahoma City, often shortened to OKC, is the capital and most populous city of the U.S. state of Oklahoma. It is the 20th-most populous U.S. city and 8th largest in the Southern United States with a population of 681,054 at the 2020 census, while the Oklahoma City metropolitan area with an estimated 1.49 million residents is the largest metropolitan area in the state and 42nd-most populous in the nation. The county seat of Oklahoma County, the city limits extend into Canadian, Cleveland, and Pottawatomie counties; however, areas beyond Oklahoma County primarily consist of suburban developments or areas designated rural and watershed zones. Oklahoma City ranks as the tenth-largest city by area in the United States when including consolidated city-counties, and second-largest when such consolidations are excluded. It is also the second-largest state capital by area, following Juneau, Alaska.
