Stockton approach handed me off to bay approach 135.4, or they meant to. In put in 134.5 (also a bay approach frequency). When I checked in the controller acknowledged me. Did not correct the frequency error and I continued in to oak. The communications on the frequency seemed odd for the sector, but I didn't catch it. On 3 mi final, with no handoff and no chance to cut in on the frequency, I changed to tower. They asked me to call -- and only then did I put together the error with the weird handling I got from approach. I use 134.5 in the morning on departure. I don't know if I input the frequency wrong or was given it incorrectly. Having 2 frequencys that similar in the same facility is confusing. I have heard others confuse them, too -- controllers included.

Title: PLT IN A BE99 ON SCK APCH IS CHANGED TO O90 APCH AND THE FREQS, 135 PT 4 AND 134 PT 5, ARE MIXED UP.
Narrative: STOCKTON APCH HANDED ME OFF TO BAY APCH 135.4, OR THEY MEANT TO. IN PUT IN 134.5 (ALSO A BAY APCH FREQ). WHEN I CHKED IN THE CTLR ACKNOWLEDGED ME. DID NOT CORRECT THE FREQ ERROR AND I CONTINUED IN TO OAK. THE COMS ON THE FREQ SEEMED ODD FOR THE SECTOR, BUT I DIDN'T CATCH IT. ON 3 MI FINAL, WITH NO HDOF AND NO CHANCE TO CUT IN ON THE FREQ, I CHANGED TO TWR. THEY ASKED ME TO CALL -- AND ONLY THEN DID I PUT TOGETHER THE ERROR WITH THE WEIRD HANDLING I GOT FROM APCH. I USE 134.5 IN THE MORNING ON DEP. I DON'T KNOW IF I INPUT THE FREQ WRONG OR WAS GIVEN IT INCORRECTLY. HAVING 2 FREQS THAT SIMILAR IN THE SAME FACILITY IS CONFUSING. I HAVE HEARD OTHERS CONFUSE THEM, TOO -- CTLRS INCLUDED.
