It is definitely some sort of routing used by a company that operates payphones. My friend called from a payphone right around the corner (in St. Louis) and this number came up on caller i.d.
Someone called on my cell phone from this number at 4:26PM. I called back and got a message that it was disconnected. Do not know who could call me from California.
It's a payphone & it's not necessarily in the 415 area code. My boyfriend called me on his way back to sacto from nevada & the 415 area code came up but I know he was somewhere between nevada & sac because I had just called him in nevada within the past hour or so. Mystery Solved!
I think this is the number for the payphone @ the Burson Market on hwy.12 between Lodi @ Valley Springs, Ca. It only SAYS it's in San Fransisco, don't know why.
