How to say "what is your car number?" in Chinese

The sentence is: 你的 (nǐ de) "your" + 车牌号 (chēpáihào) "license plate number" + 是 (shì) "is" + 多少 (duōshao) "how much/what number." It's a standard way to ask for a number.

Use this when you need to identify a car, such as when meeting a taxi or finding a parked vehicle. It's neutral and practical. In a taxi context, you might ask the driver this to confirm the car. Avoid using it for other numbers; for phone numbers, use 电话号码 (diànhuà hàomǎ).
