I received a call from this number I do not know this number at all

Got an incredibly cryptic, automated voicemail from this number at 12:17 am my local time.  It turns out it was in Arabic and said: "Yahoo Inquiry Code 4-3-6-9-1-7" after I ran it through Google Translate a bunch of times.  Not sure if some Arab fat-fingered his phone number trying to log into his Yahoo! account or if my number is being used for some no good-ery in the Middle East, but it's creepy as heck.
