Do I need to register my Mavic 2 Pro with the FAA?
All drones must be registered, except those that weigh 0.55 pounds or less (less than 250 grams) and are flown exclusively under the Exception for Recreational Flyers.
Failure to register a drone that requires registration is illegal under federal law. Drone operators who fail to register their drones may face civil and criminal charges. The civil charges may include fines up to $27,500. The criminal charges may include fines up to $250,000 and three years of imprisonment.
The Federal Aviation Administration now requires every small UAS operator to register before flight. The DJI Mavic Pro Drone unmanned aircraft system (UAS), is an aircraft without a human pilot onboard, controlled from an operator on the ground, and is required to be registered with the FAA.
You don't need a license or course to fly a drone commercially, however, you may need to do a course to fly in congested areas.
Remote ID helps the FAA, law enforcement, and other federal agencies find the control station when a drone appears to be flying in an unsafe manner or where it is not allowed to fly.
The DJI Fly application doesn't have the capability to report to CAA or FAA. However, the DJI Fly application will notify or warn you, if you are near a restricted airspace or prevent the drone to fly without authorization in restricted zone for your safety and for the safety of your drone.
The 1,000,000 total registration figure includes 878,000 hobbyists, who receive one identification number for all the drones they own, and 122,000 commercial, public and other drones, which are individually registered.
Registration costs $5, it's valid for 3 years and it only takes about 5 minutes to complete.
September 15, 2022 – DJI, the world's leader in civilian drones and aerial imaging technology, is the first drone manufacturer to submit and earn U.S. Federal Aviation Administration (FAA) approval for complying with the FAA's Remote Identification protocol.
For the most part, compliance with the 400-foot rule is a voluntary matter. There is no existing mechanism for the FAA to monitor if there are drone pilots, licensed or otherwise, who will fly above this altitude limit.
Which DJI drone does not have to be registered?
The DJI Mavic Mini weighs just 249 grams, so you can fly it in the US—and many other regions—without having to register it with the government.
In the aircraft screen, you will need to tap the white slider to the right of the unlocking license. Once you do this you will be prompted to bear responsibility for your flight, and your drone will be able to take off within the zone you unlocked.

So the Mavic 2 Pro has a Flying Weight of 907g, therefore you need to keep 50m from uninvolved people and you will need the A2 CofC. If you don't need to fly down to 50m then you can fly in the A3 category. If you have an Operational Authorisation you can fly the DJI Mavic 2 Pro under PDRA-01.
Small drones and model aircraft
You do not need to register if you'll only use a drone or model aircraft that weighs below 250g and is a toy or does not have a camera. Take a look at the registration requirements for drones and model aircraft to find out if you need to register.
Before flying your drone outdoors for the first time, you'll need to register at http://www.faa.gov/uas/registration/, if you have not already, and affix your own personal registration number to the drone.
You must label your operator ID on every drone or model aircraft you're responsible for. Use the same operator ID for all your drones or model aircraft. Always label with your operator ID, not your flyer ID.
