Narrative:

At XA50 on dec/wed/03 I was flying traffic watch and over richmond, ca. I called norcal 120.9, gave position report and asked for advisories. Route was to be highway 80 south, bay bridge then route alpha through sfo class B airspace. No squawk code was given and I remained on code 1200. After crossing the bay bridge, I requested a bravo clearance and was cleared into bravo. At hospital curve, I asked if a squawk code was needed to enter bravo. Norcal on 120.9 said current squawk was ok (1200) and 'you are cleared into bravo.' I continued down highway 101 as usual toward sfo and was given 2 aircraft TA's as I passed sfo airport. When I reached san carlos airport at 2000 ft, I asked to terminate advisories. Norcal asked for my position and I said abeam san carlos. Norcal came back and said, 'radar services terminated, squawk 1200.' I then called palo alto tower and requested transition highway 101 south. Tower said 'identify.' I did, and he said 'transition approved' and to copy sfo tower phone number and call them when I got on the ground. They gave me the administration number, so I did not talk to sfo tower. I then called palo alto tower and he said he talked to sfo tower and it was norcal's mistake and not to worry.
