Where I fly, one contacts "Cascade Approach" which is a TRACON that handles both Eugene and Medford Oregon - and the website for the local NATCA union actually has this as their recommendation, which I assume also applies to FF requests:
On initial call include: Type aircraft, full callsign, approximate location, altitude, and ATIS code. Why? The FAA requires us to get all of this information from you. If you make it a habit to provide it on initial contact we avoid tying up the frequency while we ask you for this information. This allows us to provide better service to you. Examples: "Cascade Approach, Cessna 94299 one-five north at four thousand, landing with Lima.", "Cascade Approach, Arrow 377LC over Drain at three thousand five hundred, inbound with Zulu."
