Narrative:

On the morning of 12/tue/01, we were scheduled for a XA00 am flight from ZZZ to ZZZ1. We performed our preflight duties, I preflight the aircraft, the captain obtains WX, files flight plans and pertinent information. Upon review of WX and NOTAMS, nothing is printed or in our NOTAM book of the restr airspace around ZZZ3. Our printed information from a commercial airline service and ZZZ2 state nothing about the restr airspace around ZZZ3. Our flight department called ZZZ1. For arrival and departure reservations and nothing was stated about the restr airspace around ZZZ3. FBO was also notified. Our flight was as normal as could be, VFR, clear, and smooth. After landing, we tried to receive clear once delivery at ZZZ4 which was our final destination for the day. We were asked if we had a tn number or waiver which we believed our arrival or departure reservation number would be. We found our it was not. We believed we had all the pertinent information for the safety of flight. NOTAMS from ZZZ and a commercial airline service had been checked along with printed fdc NOTAMS in our office before we departed. We have an excellent professional flight department. We would not knowingly fly to ZZZ1 had we not thought we had all the authorization to do so. If the NOTAM had been more available as to a standard NOTAM, such as our means of obtaining WX, and NOTAMS I feel we would have not proceeded. We proceeded believing we were authorized.
