Industry Canada ID (IC ID / IC) numbers are unique to a device model, but not to each device.
For example, A company may produce two types of laptops with significant variation in each laptop. They give one laptop the model APPLE 1 and the other APPLE 2. The APPLE 1 computer will get the IC ID: 579 APPLE1 and the APPLE 2 computer will get the IC ID: 579 APPLE2. Every model of APPLE 1 and APPLE 2 will get the same IC ID regardless if 1 device is produced or 1,000 are produced.
