To find the chassis number, you'll need to access either:
* The vehicle's registration document (V5C in the UK, title in the US, etc.): The chassis number will be printed on this document.
* The vehicle itself: The chassis number is usually stamped on a metal plate located in several places, depending on the make and model of the car. Common locations include:
* The dashboard: Often visible through the windscreen.
* The engine compartment: Usually on a visible part of the engine block or chassis.
* The driver's side door pillar (B-pillar): Sometimes on a sticker or plate.
* The boot (trunk): Sometimes on a plate or sticker.
* A vehicle history check service (with permission): Some services offering vehicle history reports might have access to this data, but only with the owner's consent and often for a fee. They usually obtain this information from official databases related to vehicle registration. However, they won't be able to access it using just the registration number without additional authentication that verifies ownership.
Keep in mind that attempting to obtain someone else's chassis number without their consent is illegal and unethical.
