I bought a list from List giant that over 25% deactivated phone numbers and over 15% of the people on the list had been dead for over 10 years 70% of the list didn't fall within the search parameters that I specifically paid for. In addition to this wildly inaccurate information they promised that they had run their information against the do not call list. You can probably see where this is going already. Surprise over 30% of the records where on the national do not call list.
