When I returned the call, I recieved an automated response saying that it was a leading provider of fundraising services for "nonprofit organizations, liberal arts institutions, and private colleges, etc." I have received several calls like this recently all with different phone numbers including area codes.  I'm pretty sure it isn't a scam but I have never answered when they call and they never leave messages.  I hope this helped!

Called at 4:31 pm PT on 19-July-2011.  Was not available.  No msg left on ans machine.  Caller ID shows "San Francisco CA" (415 area code is SF).  We don't know anyone in SF.  Been receiving a lot of fundraising calls in past 3 months from various numbers, no doubt computer generated numbers so they can't be traced.  These people are crazy to think that we would provide anything for unknown and unwanted solicitations.

i'm a hs senior and i've also been receiving a lot of calls from college organizations
which i never answer
so i'm assuming this is another one

My son is a senior and this number and similar numbers call our house daily and never leave a msg.

I am a senior and I'm pretty sure its a college number. I have been sending out applications and getting random calls from different institutions.
