Just like conventionally powered models, all new electric cars sold in the U.S. are required by federal law to have a sticker affixed to a side window that provides the manufacturer's suggested retail price (MSRP) and other pertinent details.
In the auto industry this is known as a "Monroney" sticker. It's named for Sen. Almer Stillwell "Mike" Monroney, who was chief sponsor of the Automobile Information Disclosure Act of 1958 that mandated use of the document that bears his name.
If you're buying a new EV, it's prudent to keep a copy of the Monroney sticker in your files for future reference. It can, for example, document for a future buyer the accessories that originally came with the vehicle. If you already own an EV but didn't hold onto the sticker, or you're not the original owner, the website MonroneyLabels.com allows you to obtain a reproduction of the original by entering the car's vehicle identification number (VIN).
At the top of every Monroney sticker, you'll find basic data that includes the vehicle's year, make, model, and applicable trim level, the interior and exterior color treatments, and its VIN.
