Narrative:
After clearing the active runway at iad, we were to taxi to the midfield ramp. Access to this ramp is obtained through the proper clearance from iad midfield ramp control. I was monitoring ground on the #1 radio and I thought my first officer had obtained the midfield clearance on the #2 radio. We taxied just inside the midfield ramp area when I realized we didn't have a clearance. I immediately stopped the aircraft and obtained the proper clearance. Luckily there was no traffic or congestion into and out of the midfield ramp. I had believed that the first officer had obtained the clearance on the #2 radio. I normally verify clearance into the ramp but the first officer was in the middle of a passenger announcement. To prevent this from happening in the future, I would recommend that both pilots verify clrncs into ramps, across runways, etc. If the other pilot can't verify the clearance, the aircraft should be stopped until everything is figured out.

Title: A TAXIING J3200 INTRUDES ON THE MIDFIELD RAMP AREA WITHOUT BENEFIT OF CLRNC FROM THAT CTLR. THE FO WAS ON PA AND FAILED TO COORD WITH THE CAPT.
Narrative: AFTER CLRING THE ACTIVE RWY AT IAD, WE WERE TO TAXI TO THE MIDFIELD RAMP. ACCESS TO THIS RAMP IS OBTAINED THROUGH THE PROPER CLRNC FROM IAD MIDFIELD RAMP CTL. I WAS MONITORING GND ON THE #1 RADIO AND I THOUGHT MY FO HAD OBTAINED THE MIDFIELD CLRNC ON THE #2 RADIO. WE TAXIED JUST INSIDE THE MIDFIELD RAMP AREA WHEN I REALIZED WE DIDN'T HAVE A CLRNC. I IMMEDIATELY STOPPED THE ACFT AND OBTAINED THE PROPER CLRNC. LUCKILY THERE WAS NO TFC OR CONGESTION INTO AND OUT OF THE MIDFIELD RAMP. I HAD BELIEVED THAT THE FO HAD OBTAINED THE CLRNC ON THE #2 RADIO. I NORMALLY VERIFY CLRNC INTO THE RAMP BUT THE FO WAS IN THE MIDDLE OF A PAX ANNOUNCEMENT. TO PREVENT THIS FROM HAPPENING IN THE FUTURE, I WOULD RECOMMEND THAT BOTH PLTS VERIFY CLRNCS INTO RAMPS, ACROSS RWYS, ETC. IF THE OTHER PLT CAN'T VERIFY THE CLRNC, THE ACFT SHOULD BE STOPPED UNTIL EVERYTHING IS FIGURED OUT.
