Vehicle ICCID can be found in the central control screen infotainment system of the car. It is an integrated circuit card identification code used for telematics functions, essentially a built-in SIM card in the infotainment system. This serves as a protective measure against software piracy. When activating the infotainment system, the vehicle generates this identification code, which is created by the computer based on the hardware and software information of the system. The code consists of 20 digits. The SN code is also required when the owner registers and activates the infotainment system, and it can be queried at 4S stores. This is an identification code assigned by the software developer to the software, similar to a person's ID number. Users must know this serial number to use the software.

Last time I looked for the ICCID number in my own car, I found it on the back of a small black box in the glove compartment. That thing is part of the vehicle's SIM card, used for connectivity features like remote start or navigation. Most car models hide it in discreet locations, such as under the dashboard, behind the side panels of the trunk, or near the wiring harness behind the steering wheel. The location varies by brand—my German car prefers the glove box, while Japanese models might place it in the trunk. If you can't find it, don't force it open to avoid damaging the electronics; it's better to check the owner's manual or ask the dealership. The ICCID looks like a long string of numbers and is quite important—without it, the car can't connect to the internet. During routine car washes or inspections, take a quick look to ensure the card holder isn't loose.

ICCID is essentially the SIM card number in the vehicle's communication module, commonly found on T-Box devices during car repairs. The module is usually installed behind the dashboard or in a corner of the trunk for dust and shock protection. Designs vary by model—BMW likes to tuck it into the center console seams, while Toyota prefers placing it under the seats. When searching for it, gently pry open plastic covers to spot the small label. It's crucial for remote diagnostics and emergency calls, as important as a phone SIM, so avoid tampering. If the location is unclear, use a phone flashlight or scan with the manufacturer's app—no forceful disassembly, as the circuitry is fragile.

My car's ICCID is clearly printed on a small metal box next to the spare tire compartment in the trunk. This is a standard configuration in modern vehicles for easy eCall emergency services or OTA updates. The location is typically in an easily accessible but less frequently used area, such as the trunk, glove compartment layer, or a corner of the engine bay. When searching, first turn off the engine to avoid electric shock, then gently pull open the plastic panel. The ICCID serves as a serial number, managing the vehicle's internet connectivity like an ID card. If unfamiliar, consult the manual or search model-specific forums—experienced drivers know this well. Remember to wear gloves when handling and avoid oil contamination.
