Do I Need to Register My Drone? Drone Rules by Weight and Country
Whether you need to register a drone depends on two numbers: its take-off weight and where you fly it. The thresholds are not the same everywhere. A 249 g drone needs no registration for hobby flying in the US, but in the UK it now needs two IDs, and in Japan anything of 100 g or more has to be registered. Use the tool below to see the rules that apply to your drone, then read the country notes for the details the tool summarises.

A summary of national rules for typical flights, not legal advice. Specific operations (night, near airports, over people, beyond line of sight) have extra rules. Always check the authority linked in your result before flying.

United States: 250 g for hobby flying, any weight for work
The FAA splits drone flying into recreational and everything else. Recreational pilots must pass the free TRUST test at any weight and register any drone over 250 g, at $5 for three years, marking the registration number on the aircraft. Registered drones must broadcast Remote ID, either built in or through an add-on module. Anything flown for work, from real-estate photos to a paid YouTube video, falls under Part 107: the pilot needs a Remote Pilot Certificate and the drone must be registered whatever it weighs. The 400 ft ceiling and line-of-sight rule apply to both.
Since December 2025, which drones can be sold in the US has become a separate question from which ones can be flown. Registration rules do not change for drones already in the country; see our US drone ban checker for the sales side.
United Kingdom: the 100 g rule from 1 January 2026
The UK made the biggest change of any major market this year. From 1 January 2026, anyone flying a drone of 100 g or more needs a Flyer ID, obtained by passing the CAA’s free online theory test. An Operator ID, which carries an annual fee and must be displayed on the aircraft, is required from 250 g, and from 100 g if the drone has a camera. That means a DJI Neo 2 at 151 g, which needed nothing in 2025, now needs both IDs.
The UK also introduced its own class marks, UK0 to UK6, with EU C-class marks accepted as equivalent until 31 December 2027. Remote ID is being phased in: class-marked UK1, UK2, UK3, UK5 and UK6 drones must broadcast it from 2026, and UK0 drones with a camera, UK4 drones and legacy unmarked drones follow from 1 January 2028. Night flights now require a green flashing light. The height limit stays at 120 m.
European Union: operator registration and the open category
EASA rules apply across EU member states plus Norway, Iceland, Liechtenstein and Switzerland. You register as an operator, not per drone, with your national aviation authority, and display the operator number on each aircraft. Registration is required for any drone of 250 g or more, and for lighter drones that carry a camera, unless they are classed as toys. The operator number from one EU country is valid across the others.
Pilot training depends on the drone’s class mark and weight. Under 250 g (C0) there is no exam, only the manufacturer’s instructions. From 250 g, pilots complete the online A1/A3 training and exam; a C1 drone such as a 900 g class-marked model can fly in A1 near people, while an unmarked legacy drone over 250 g is limited to A3, away from people. For C2 drones up to 4 kg, the A2 certificate allows closer flying. C1, C2 and C3 drones must broadcast direct Remote ID. The height limit is 120 m, and individual countries can add geographic restrictions.
Canada: micro drones under 250 g, certificates above
Transport Canada treats drones under 250 g as micro drones: no registration and no pilot certificate, though pilots must still fly safely and away from aircraft and people. From 250 g to 25 kg, the drone must be registered and marked, and the pilot must hold a Basic or Advanced drone pilot certificate, depending on where they fly. Canada applies the same rules to recreational and commercial flying. In 2025 a new Level 1 Complex category added beyond-visual-line-of-sight operations for certified operators. The height limit is 122 m (400 ft).
Australia: no registration for hobby flying, but work changes everything
CASA does not require recreational pilots to register drones or hold accreditation, provided they follow the standard operating rules: 120 m maximum height, daylight only, visual line of sight, 30 m from people and not over crowds. The moment a flight is for work, including a business’s own social media, the drone must be registered at any weight (free up to 500 g, a fee above) and the pilot needs either operator accreditation or a Remote Pilot Licence. Above 2 kg, a RePL and an operator certificate are generally required.
Japan: the lowest threshold of the major markets
Japan has required registration from 100 g since 20 June 2022, with the registration code displayed on the aircraft and Remote ID broadcast. Flights under the Civil Aeronautics Act are limited to 150 m and need permission over densely inhabited districts, at night, or beyond line of sight. Under 100 g a drone is treated as a model aircraft, but it still cannot fly near airports or key facilities. Visitors can register through the MLIT portal before travelling.
Why 250 grams matters, and where it no longer does
For years, 250 g was the line that mattered: DJI designed its Mini series to sit just under it, and most countries used it as the point where registration began. That is still true in the US, Canada and the EU. It is no longer true in the UK, which lowered the Flyer ID threshold to 100 g on 1 January 2026, or in Japan, which has registered drones from 100 g since June 2022. A sub-250 g drone with a camera now needs paperwork in more places than it used to.
Weight here means take-off weight, including the battery, propellers and anything you attach. A larger battery or an accessory can push a 249 g drone over the line: DJI’s own Plus batteries do exactly that on the Mini 3 Pro and Lito X1. We cover a real example in DJI Mavic 4 Pro weight explained, and how the leaked Neo 3 compares in DJI Neo 3 weight. If you are still choosing a drone, our drone finder lets you keep the search under 250 g.
Remote ID explained
Remote ID is a broadcast, usually over Wi-Fi or Bluetooth, of a drone’s identity, position, altitude and take-off point, which anyone with a receiver app can read. It is the drone equivalent of a number plate. The US requires it for every registered drone; the EU for C1, C2 and C3 class drones; Japan for everything over 100 g; and the UK is phasing it in through 2028. Most drones sold since 2023 have it built in. Older drones can add a broadcast module, which counts toward take-off weight.
Frequently asked questions
Do I need to register a drone under 250 g?
In the US, Canada and for hobby flying in Australia, no. In the UK you need a Flyer ID from 100 g and an Operator ID if it has a camera. In the EU you must register as an operator if it has a camera. In Japan, registration starts at 100 g.
Do I need to register a DJI Mini 4 Pro or Mini 5 Pro?
In the US, not for recreational flying, because both stay under 250 g with the standard battery. In the UK you need a Flyer ID and an Operator ID. In the EU you need operator registration because they have cameras. Fit a Plus battery and the drone crosses 250 g in every market.
Do I need to register a DJI Neo or Neo 2?
Not in the US or Canada, where both sit well under 250 g. In the EU, yes: they have cameras, so operator registration applies. In the UK, both now need a Flyer ID and an Operator ID because they weigh over 100 g and carry a camera. In Japan, yes, from 100 g.
Does a drone used for work need registering in the US?
Yes. Under Part 107, every drone flown for work must be registered with the FAA regardless of weight, and the pilot needs a Remote Pilot Certificate.
Does the weight include the battery?
Yes. Registration thresholds use take-off weight, which includes the battery, propellers, a memory card and any accessories fitted for the flight.
Can I fly my registered drone in another country?
Registration is national. Visiting pilots usually have to register locally or with the regional system: an EU operator number works across EASA countries, but a US registration does not count in the UK or Japan.
What is Remote ID?
A broadcast of the drone’s identity and position that people on the ground and authorities can receive. The US requires it for registered drones, the EU for C1–C3 class drones, and Japan from 100 g. The UK is phasing it in through 2028.
What happens if I fly without registering?
Fines and, in some countries, confiscation. UK penalties run to £2,500, Canada fines individuals up to C$5,000, and the FAA can impose civil penalties for unregistered drones over 250 g.
