This number called the office yesterday after I left. I suspect it might be another number for "Local Maps" verification.
Also, it could be related to following numbers:
http://800notes.com/Phone.aspx/1-575-613-7462/2 -- Another number in the same block
http://800notes.com/Phone.aspx/1-605-496-0703/2 -- Used the exact same caller id
Called me yet again with this spoof number. The last time was back in September. These jerks think anyone will answer by recycling the spoof numbers. They're idiots.
