Narrative:
Flight abc air carrier X (den-phl) was on the ground in phl the same time flight abc air carrier X (phl-bdl) was taxiing out for takeoff. ATC delays due to WX caused flight abc air carrier X (den-phl) to be over 1 hour late arriving phl. I started my shift at XA00 and within the first min on duty, I received a message of a flight number overlap. I then checked both flts and found that flight abc air carrier X (den-phl) was taxiing to the gate the same time flight abc air carrier X (phl-btv) was taxiing to take off. I sent a message to both flts warning them of the situation, and ti told them to verify their call sign when talking to ATC. I tried calling our ramp control in phl, but received a busy signal 4 times. At XA06, flight abc air carrier X (den-phl) terminated at the gate. At XA10 flight abc air carrier X was airborne. Had the computers caught this overlap earlier, the flts could have been stubbed to have different flight numbers.
Original NASA ASRS Text
Title: 2 ACFT WITH THE SAME FLT NUMBER WERE ON THE GND AT PHL AT THE SAME TIME, ONE ARRIVING, THE OTHER DEPARTING.
Narrative: FLT ABC ACR X (DEN-PHL) WAS ON THE GND IN PHL THE SAME TIME FLT ABC ACR X (PHL-BDL) WAS TAXIING OUT FOR TKOF. ATC DELAYS DUE TO WX CAUSED FLT ABC ACR X (DEN-PHL) TO BE OVER 1 HR LATE ARRIVING PHL. I STARTED MY SHIFT AT XA00 AND WITHIN THE FIRST MIN ON DUTY, I RECEIVED A MESSAGE OF A FLT NUMBER OVERLAP. I THEN CHKED BOTH FLTS AND FOUND THAT FLT ABC ACR X (DEN-PHL) WAS TAXIING TO THE GATE THE SAME TIME FLT ABC ACR X (PHL-BTV) WAS TAXIING TO TAKE OFF. I SENT A MESSAGE TO BOTH FLTS WARNING THEM OF THE SIT, AND TI TOLD THEM TO VERIFY THEIR CALL SIGN WHEN TALKING TO ATC. I TRIED CALLING OUR RAMP CTL IN PHL, BUT RECEIVED A BUSY SIGNAL 4 TIMES. AT XA06, FLT ABC ACR X (DEN-PHL) TERMINATED AT THE GATE. AT XA10 FLT ABC ACR X WAS AIRBORNE. HAD THE COMPUTERS CAUGHT THIS OVERLAP EARLIER, THE FLTS COULD HAVE BEEN STUBBED TO HAVE DIFFERENT FLT NUMBERS.
