Operator ID and Flyer ID: the two UK registrations
In the UK two IDs exist side by side and never replace one another. One names who is responsible for the aircraft, the other who flies it.

Two IDs, two roles
The Operator ID belongs to the person or company responsible for the drone. It goes on the body of every aircraft, renews every year, and requires you to be 18. It is needed from 250 g, and from 100 g if the aircraft carries a camera.
The Flyer ID belongs to whoever holds the controller. You get it by passing a free online theory test, and it lasts five years. It is needed from 100 g. One person often holds both, but the two steps stay separate.
Registering with the CAA
Both IDs come from the same online service run by the Civil Aviation Authority.
- 1
Weigh the aircraft, camera included
Under 100 g with no camera, nothing is asked. Above that, weight and the presence of a camera decide which of the two IDs you need, and often you need both.
- 2
Pass the Flyer ID test
A free online questionnaire you may retake. The Flyer ID is issued straight away and lasts five years.
- 3
Register the Operator ID and display it
Registration is paid and annual, a little over twelve pounds at the current rate. The number must stay readable on the outside of every drone you are responsible for, and the same number covers the whole fleet.
Frequently asked questions
Do I really need both?
Usually yes. Flying your own drone over 250 g makes you both the operator and the remote pilot, so you need an Operator ID and a Flyer ID.
Does my EU registration count in the UK?
No. Since Brexit the British framework stands apart from the EASA one, and an operator number issued by a member state is not recognised there. You need a British Operator ID.
How long do they last?
The Operator ID renews every year and stays paid. The Flyer ID lasts five years and stays free. The two dates therefore never line up.
