A drone needs to be registered with the FAA if it's over a certain weight limit. For recreational drone operators, the weight limit for registration is 0.55 pounds (250 grams). Drones weighing more than this require registration with the FAA. However, if the drone is being used for commercial purposes, regardless of its weight, it needs to be registered with the FAA and the operator must obtain a Part 107 remote pilot certificate.
