Yes, if you’re flying a drone under the Part 107 regulations, it needs to be registered ‘commercially’ — even if the drone has already been registered recreationally.

Commercial registration is really easy — it costs $5 and is good for three years. You’ll need to put in the make, model, and serial number of the drone, so have this information handy.
