Flight Service called for a clearance off of CBG (Cambridge; MN) on a Learjet 55. I did not have a flight plan on this aircraft; so I added the call sign to my flight list and saw the Flight Plan. I issued a clearance to the Learjet 55 from Cambridge to GXY via direct. Flight Service read back cleared from Cambridge to GXY via direct. It was not until after I hung up the line did I realize that the aircraft might be departing a different airport (CBF); which is Council Bluff; IA. I tried to call Flight Service ASAP but got the normal run around of no idea who talked to me; what was the call sign again; where did he depart. I contacted the sector that CBF lies in; and advised them of the situation; and at the same time saw the aircraft code pop up off of CBF; not CBG. OMA Approach works this airspace and said that everything was fine; no aircraft loss of separation happened. [We need to] have a way to contact FSS when this happens; or for any other manner. It is almost impossible to get a hold of the FSS specialist that you had talked to previously; and when time is critical; as was the case here; it would be helpful to know who called you and how to get a hold of them again.
I was working the desk when the Sector 10 Controller appeared to have an anomaly. He had issued a clearance through Flight Service off of CBG; when in fact the flight plan was off of CBF. The Controller caught the error after hanging up with Flight Service and quickly realized the Flight Service person's mistake and did some very quick internal coordination with the affected sector; well outside of our airspace at CBF. There was no loss of separation. Flight Service needs to be careful of its identifiers!!
ZMP Controller described an unsafe condition report when Flight Service failed to note the correct departure airport on the Flight Plan and the aircraft departed in another Controller's airspace.
