This *is* Facebook's auto-call that confirms your details with a recorded message, giving you a code to enter to verify your identity. If you set up a business page or something similar, you are required to verify your identity. If you received a call and didn't set a page up, it's likely that someone entered a wrong number on Facebook by mistake.
If you are getting a call from this number that isn't related to Facebook, then yes, someone is spoofing the number and scamming you.
Were you trying to sign into your Facebook at the moment of the call? I get an automatic call from FB (coming from this number) whenever i try to sign in my FB from a new computer or after i cleared the history. If you weren't signing in, someone else might have been trying to break into your acct
This was a message from FACEBOOK verifying they have determined I am who I say I am in order to verify my facebook business page. I requested the verification.
