The 725 area code will be in southern Nevada in 2014. Right now, it is not a valid area code. Any call coming in from 725 is a fake call. Do not volunteer ANY information to a caller from area code 725 (for the rest of 2013).
These jerks keep calling but down have any message. If you try to call them back you can't connect to them. Need to find out who these as*ho*es are and shut them down.
