How to Register a Drone

Drone registration in the United States comes down to a single question: does the aircraft, with everything bolted to it at the moment of takeoff, weigh 250 grams or more? If yes, it must be registered before it flies. If you are flying under Part 107 for work or for a business, the answer to that question stops mattering, because Part 107 aircraft must be registered at any weight, including a featherweight aircraft under 100 grams.

The 250 gram threshold, exactly

The FAA sets the recreational registration threshold at 250 grams, equivalent to 0.55 lb, at takeoff weight. That figure includes the aircraft body, the battery installed for that flight, and anything else physically attached: propeller guards, ND filters, an anti-collision strobe, a payload, or any aftermarket accessory. It does not matter what the aircraft weighs stripped down in the box; what matters is what leaves the ground.

This is why the sub-250 gram class of aircraft, including the DJI Mini 4K, the DJI Neo 2, the DJI Flip and the DJI Mini 5 Pro, is popular with recreational flyers who want to skip the registration step entirely. It is also why fitting the extended DJI Mini 4 Pro Intelligent Flight Battery Plus to a Mini-class aircraft is worth checking against the spec sheet first: some Mini 3 and Mini 4 Pro configurations cross 250 grams with the larger pack fitted, which changes the registration answer for that specific loadout even though the base aircraft ships under the line.

How to actually register

Registration happens through the FAA DroneZone website, not through a third-party app or a state agency. Create an account, select the recreational or Part 107 path depending on how the aircraft will be flown, provide the required information, and pay the registration fee. The recreational path issues a single registration number that covers every qualifying recreational aircraft you own; you do not register each drone separately under that path. The Part 107 path is different: each aircraft flown commercially gets its own individual registration record, even if the same person already holds a recreational number for other aircraft.

If you plan to fly commercially at all, even occasionally, register under Part 107 for that aircraft rather than relying on a recreational number, because a recreational registration does not cover any flight in furtherance of a business, paid or unpaid. That distinction is explained fully in our Part 107 vs recreational rules comparison.

Marking the aircraft

Once registered, the registration number must be physically marked on the aircraft in a legible, accessible location on the exterior, readable without opening a compartment or removing a panel. Writing it directly on the airframe with a permanent marker satisfies the requirement, and many pilots instead use a small printed or engraved label affixed to the underside or a landing leg. The number should be durable enough to survive normal handling and weather exposure for the life of the registration.

What registration does not cover

Registration is one requirement among several, and it does not substitute for any of the others. Recreational flyers still need to pass the free TRUST test before flying at all. Every aircraft, registered or not, still needs to comply with Remote ID rules once airborne. And flying in controlled airspace still requires an authorization through LAANC or DroneZone, regardless of whether the aircraft is registered. Registration is the paperwork that identifies the aircraft; it is not a license to fly wherever or however you want.

What happens if you fly unregistered when you should not

Flying an aircraft that requires registration without one exposes the operator to civil and, in more serious cases, criminal penalties under federal law. Beyond the legal exposure, an unregistered aircraft cannot be traced back to its owner if it is lost, stolen, or involved in an incident, which is precisely the traceability problem registration exists to solve. The cost and time to register is minor compared to that risk, and for most sub-250 gram recreational flyers the entire question is moot: buy an aircraft under the line and the registration step never comes up in the first place.

Buying a used drone and checking its registration status

A used aircraft purchase raises a registration question the original buyer never had to think about: the previous owner's registration does not transfer automatically to a new owner, since recreational registration is tied to the person flying, not the specific airframe, and Part 107 aircraft registration is tied to the specific registered owner of record. If you buy a used aircraft at or above the 250 gram threshold, register it under your own account before flying it, even though it may already carry a previous owner's registration marking on the body somewhere. Remove or cover any old registration marking and apply your own, since flying under someone else's registration number, even inadvertently on a used aircraft that still has the old owner's marking, does not satisfy your own registration obligation as the person actually operating the aircraft.

This is also a good moment to confirm the aircraft's firmware, Remote ID compliance status, and general mechanical condition before the first flight under new ownership, since a used aircraft's full history, including any past crash damage, may not be fully known. Treat a first flight on any newly acquired used aircraft as more cautious than a routine flight on a familiar, known-good aircraft, starting with the same low, careful hover recommended for a first flight on any new build.

Registration renewal and keeping records current

Registration is not a one-time transaction. Both recreational and Part 107 registrations are valid for a set period from the date of issue, after which renewal is required to remain legal to fly. The exact renewal window and fee are set by the FAA and worth confirming directly at DroneZone at the time you register, since program specifics do get updated periodically. Set a calendar reminder well ahead of the expiration date rather than relying on memory, since flying on an expired registration carries the same consequences as never having registered at all. If you sell an aircraft or permanently retire it from flying, update or cancel that specific registration record where the process allows it, both to keep your own records accurate and to avoid any confusion if the aircraft changes hands.

Keep a copy of your registration confirmation, whether the recreational number or an individual Part 107 aircraft registration, somewhere you can access it quickly, alongside the other compliance documents covered in the field kit guide. A registration number marked on the aircraft satisfies the physical marking requirement, but having the underlying confirmation and registration details on hand is useful if you are ever asked to demonstrate that the aircraft is properly registered, particularly for a commercial operator working on an unfamiliar site.

Registering multiple aircraft as your fleet grows

A recreational flyer who buys additional sub-250 gram aircraft over time does not need to do anything further; the exemption applies per aircraft based on weight, not per owner, so each new sub-250 gram purchase simply continues to fall outside the requirement. The moment a recreational flyer adds an aircraft at or above 250 grams, that specific aircraft falls under the existing recreational registration number already on file, since one number covers every qualifying recreational aircraft an individual owns. Commercial operators expanding a fleet under Part 107 face a different bookkeeping task: each additional aircraft used for commercial work needs its own individual registration record added to the operator's DroneZone account, which is worth budgeting time for whenever a new aircraft joins a working fleet rather than assuming the existing registration automatically extends to it.

Weighing an aircraft accurately before you decide

Do not rely on the manufacturer's base spec sheet weight if you fly with accessories attached. Weigh the aircraft on a real kitchen or postal scale with the battery, props, any filter, and any guard installed exactly as you intend to fly it. A few grams over the line is still over the line. Our weight and registration calculator walks through this with your specific accessory loadout, and the drone weight classes reference lists where popular aircraft land relative to the threshold.
