I have yet to hear of phone companies doing that, they might, but I haven't heard of it. They also have VERY strict PUC And FCC guidelines for maintaining the integrity of their customers accounts. so idk. But FWIW Telemarketers are not stupid, they pay people some very smart people, and sometimes the marketeers just dial every number in sequence using an auto dialer, except those in the do not call list, until they get someone to answer. They just go down the list starting at 000-0001, 000-0002 etc etc et al, for example and eventually reach your number. Your number is not unique like a finger print is to you. several people have already had your number before you. that is maybe why you also get some wrong number looking for a certain person. Your best bet is when a telemarketer call comes thru pick up ant tell them to put you on a do not call list. If they keep calling then you call your phone company and tell them. Try to make use o fthe anonymous call rejection, call block, and Do Not Disturb Registry that the government set up. anytime you get a new number, always go back to the site and re-register the new number. If calls get excessively bad then you might want to consider a phone number change, or buy a hardware caller id blocker at a local electronics retailer.
