To fly IFR in controlled airspace you must have a clearance.

To have a clearance you have to file for it.

You can file by phone, computer or radio, but you must file it.


Where does a "pop-up" clearance fit into this?

By radio.

If you get a popup clearance from ATC.. the controller/specialist is
entering your information into the computer, and requires much if not
all the same information as if you filed on the phone.

Call sign, type/identifier, /whatever .. souls on board, etc. Point of
origin tends to be where you are at, even if airborne.

You are filing a flight plan by radio.
