The first thing to settle after buying a drone in Korea is whether the aircraft has to be registered. If registration is required and you fly without it, you are exposed to an administrative fine, and you also cannot move on to the steps that follow, such as business registration or insurance. Whether the duty applies comes down to two things: the weight of the aircraft and the purpose you fly it for.
The two criteria that decide whether you must register
Under the Aviation Safety Act, drones are classified as ultra-light flight devices (초경량비행장치), and the duty to file a 기체 신고 (device registration) is judged as follows.
- Commercial purposes: if you fly for payment — filming, surveying, crop spraying, inspection — the aircraft must be registered regardless of weight. Even a 250g-class mini drone has to be registered the moment it is put to work in a business.
- Non-commercial (hobby or personal use): registration applies to aircraft with a maximum take-off weight above 2kg. Entry-level and toy-grade aircraft at 2kg or under are exempt from registration, but the operator's duties (조종자 준수사항) apply at every weight without exception.
- Unmanned airships: exempt from registration when the empty weight is 12kg or less and the length is 7m or less.
The weight that matters here is maximum take-off weight, with the battery, camera, gimbal and every attachment included. Judging from the airframe weight printed in the catalogue is exactly how owners end up over the line without realising it. Put the aircraft on a scale with all your filming equipment fitted; that is the number that counts.
For businesses, the steps come in a fixed order
A hobby flyer is finished after a single registration. Anyone preparing a business needs to know first that three procedures are interlocked in sequence.
- Step 1 — insurance: you need cover in place before you can file the device registration at all.
- Step 2 — device registration: register the insured aircraft and receive a registration number.
- Step 3 — business registration: only once device registration is complete can you register an ultra-light flight device business (초경량비행장치사용사업).
It is common to lose weeks by starting from business registration without knowing this order. If you have a fixed opening date, work backwards from it and lock in the insurance date first.
Where and how to file
The fastest route is online through the Drone One-Stop Civil Service (드론 원스톱 민원서비스, drone.onestop.go.kr). You enter owner and aircraft details and attach documents of the following kinds.
- Material confirming the specifications and performance of the aircraft
- A side-view photograph of the aircraft
- Proof of ownership, such as a purchase receipt, a transaction statement or a transfer certificate
- For commercial use, documentation confirming that insurance is in force
Once the filing is accepted a registration number is issued, and that number must be marked on the outside of the aircraft so it can be identified. A sticker or an engraving are both acceptable; what matters is that it sits where an inspector can read it immediately. One-Stop handles not only device registration but flight approval and the aerial photography permit administered by the Ministry of National Defense, so creating an account early makes every later step easier.
Mistakes people make on a first registration
- Reading only the airframe weight, concluding the drone is under 2kg, and skipping registration entirely
- Starting as a hobbyist, then accepting paid filming work — which makes the use commercial — without registering
- Receiving a registration number and flying without marking it on the aircraft
- Assuming that device registration on its own permits every kind of flight
- Selling an aircraft second-hand without filing a cancellation or a change of registration
Registration needs upkeep afterwards
Device registration is not a one-time event. When the owner or the address changes, or when the aircraft is transferred to or from someone else, you must file a change of registration; when the aircraft is scrapped or you no longer hold it, you must file a cancellation. Selling second-hand without cancelling is the one that bites — problems that later involve that aircraft can stay attached to the previous owner.
Registration is also a separate track from pilot certification. Operator certificates (조종자 증명) are administered by the Korea Transportation Safety Authority (TS) and split by maximum take-off weight: Class 1 covers aircraft above 25kg up to 150kg empty weight, Class 2 above 7kg to 25kg, Class 3 above 2kg to 7kg, and Class 4 above 250g to 2kg. Classes 1 to 3 are open to applicants aged 14 and over, while Class 4 can be obtained from age 10 by completing online training alone. Finishing registration does not unlock every flight: you still need the operator certificate matching your weight band, and flight approval depending on airspace and altitude. Understanding the three as a single flow is what stops steps from falling through the cracks. Laws and detailed criteria can be revised, so check the current rules on the Drone One-Stop Civil Service or in Ministry of Land, Infrastructure and Transport notices.
Light Beyond Drones runs drone training and aerial filming side by side in Daejeon, so our certification courses open the actual device registration and flight approval screens and work through them live rather than in the abstract. Owners registering an aircraft for the first time usually get stuck on the weight criteria alone. Tell us what you own and what you intend to use it for, and we will set out whether it must be registered, which certificate class you need, and the order of steps if you later turn the work into a business. You are welcome to send that along with a training or filming enquiry.
