Car number
🚗🔢 车 (car) + 号 (number) = license plate or vehicle ID number
车 means vehicle and 号 means number or designation. Together they refer to a car's identifying number, like a license plate or fleet ID. 号 also appears in 号码 (number) and 学号 (student ID).
车 — pictograph of a chariot/cart
车 is a pictograph originally drawn as a top-down view of a chariot, showing the axle, wheels, and carriage box. The ancient form 車 clearly depicted two wheels connected by an axle. It still means vehicle, cart, or car today.
号 — mouth 口 + tiger 虎
Originally written 號, combining 口 (mouth, indicating a cry or call) with 虎 (tiger) as the phonetic and a hint at a loud roar. It first meant to shout or call out, then extended to a name, title, or signal. The simplified form 号 keeps only the upper element.
