This is a company in Portland, Oregon that has computerized auto-dialers that dial all possible cell numbers. Actual working cell phone numbers are difficult for telemarketers to obtain. This company obtains working cell numbers and sells them for a premium price to telemarketers. If the random blast call is answered, it is assumed that this is a working cell number and it is then sold to telemarketers. IF YOU WANT YOUR CELL NUMBER TO REMAIN STRICTLY PRIVATE, never answer any call if you do not recognize it!!!
