A vanity plate or personalized plate (United States and Canada); prestige plate, private number plate, cherished plate or personalised registration (United Kingdom); personalised plate (Australia, New Zealand, and United Kingdom) or custom plate (Canada, Australia and New Zealand) is a special type of vehicle registration plate on an automobile or other vehicle. The owner of the vehicle pays extra money to have their own choice of numbers or letters, usually portraying a recognizable phrase, slogan, or abbreviation, on their plate. Sales of vanity plates are often a significant source of revenue for North American provincial and state licensing agencies. In some jurisdictions, such as British Columbia, vanity plates have a different color scheme and design. North America Vanity plates are issued by every U.S. state and the District of Columbia, and every Canadian province except Newfoundland and Labrador. In 2007, the American Association of Motor Vehicle Administrators (AAMVA) and Stefan Lonce, author of License to Roam: Vanity License Plates and the Stories They Tell, conducted North America's first state by state and province by province survey of vanity plates, revealing that there are 9.7 million vehicles with personalized vanity license plates. The survey ranked jurisdictions by "vanity plate penetration rate", which is the percentage of registered motor vehicles that are vanitized. Virginia has the highest U.S. vanity plate penetration rate (16.19%), followed by New Hampshire (13.99%), Illinois (13.41%), Nevada (12.73%), Montana (9.8%), Maine (9.7%), Connecticut (8.14%), New Jersey (6.8%), North Dakota (6.5%) and Vermont (6.1%). Texas had the lowest vanity plate penetration rate (0.5%). Virginia's high rate of vanity plates, in particular, was attributed to the low cost per annum compared to a standard plate: the state charges $10 more for vanity plates than for state-issued plates, compared to $50 more in Maryland and $100 more in Washington, D.C. According to the Federal Highway Administration, in 2005 there were 242,991,747 privately owned and commercial registered automobiles, trucks, and motorcycles in the U.S., and 3.83% of eligible U.S. vehicles have vanity plates. Ontario had the highest Canadian vanity plate penetration rate (4.59%), followed by Saskatchewan (2.69%), Manitoba (1.96%), the Yukon (1.79%), and the Northwest Territories (1.75%). British Columbia had the lowest vanity plate penetration rate (0.59%) among those provinces that issue vanity plates. According to Statistics Canada, in 2006 there were 14,980,046 registered motor vehicles (excluding buses, trailers, and off-road, farm and construction vehicles) in the provinces and territories that issue
