AFTER THEIR SCHEDULED FLT WAS CANCELED; FLC NEVER RECEIVED THE IFR CLRNC FOR THE FERRY FLT THEY WERE TO FLY.

Narrative

WE ARRIVED AT THE ACFT. COMPLETED THE PREFLT CHKS; INITIALED THE ACARS; RECEIVED THE CLRNC VIA PRE-DEP CLRNC; SET UP THE RADIOS AND BRIEFED THE DEP. THE FGT WAS THEN CANCELLED AND WE WERE TO FERRY TO A NEW DEST. A NEW RELEASE WAS ATTAINED; RADIOS WERE RESET AND NEW DEP BRIEF DONE; MORE FUEL ADDED; TKOF ALTERNATE REQUESTED; DEICING PROCS REVIEWED; ETC. WE PUSHED OFF GATE. TAXIED TO DEICING PAD VIA GND CTL CLRNC USING OUR NEW FLT NUMBER CALL SIGN. AFTER WAITING 2 HRS TO GET DEICED; WE CONTACTED GND CTL FOR TAXI; THEN CALLED TWR FOR TKOF CLRNC. WE WERE CLRED FOR TKOF; SWITCHED OVER TO DEP. WE CONTACTED DEP WITH OUR NEW CALL SIGN AND THEY REQUESTED OUR SQUAWK CODE AND FIRST FIX. WE REPLIED WITH OUR SQUAWK (WHICH WAS OUR ORIGINAL SQUAWK FROM OUR CANCELLED FLT) AND OUR NEW FIX. ATC ASSIGNED A NEW SQUAWK CODE. WE ASKED IF THERE WAS A PROB WITH OUR CLRNC. ATC WAS NOT SURE OF OUR QUESTION; GAVE US A NEW FREQ AND SAID 'HAVE A GOOD DAY.' FLT CONTINUED NORMALLY. AFTER FIRST FLT WAS CANCELLED AND NEW CLRNC WAS REQUESTED VIA ACARS PRE-DEP CLRNC; SEEMS TO BE WHERE THE PROB STARTED. THERE WERE MANY DISTRS AT THIS TIME AND PERHAPS THE ACARS WAS NOT RECEIVED OR WE FAILED TO SEE IT. THE ACARS WAS ALSO BEING USED TO COMMUNICATE TO DISPATCH AND KEEP ABREAST OF DEST WX AND ALTERNATE WX WHICH MAY HAVE CAUSED US TO MISS THE CLRNC. THROUGHOUT COM WITH ATC; UNTIL DEP; THERE WAS NO VERIFICATION OF SQUAWK CODE. IT MIGHT BE A GOOD IDEA TO VERIFY SQUAWK AND CURRENT ATIS WITH INITIAL GND CTL CONTACT; OR A SQUAWK CHK ON AFTER START CHK MAY ALSO PREVENT THIS TYPE OF PROB.
