We have the entire telephone directory change history from mid 2002 to the present.
We can tell you exactly when disconnected records were disconnected. Using this information, we can determine the probable age of your database and the average monthly churn on your listings.
Stop spending money on bad listings. Every month, approximately one million of the 115 million national telephone listings change. By eliminating disconnected listings from your campaigns, you're saving yourself expensive direct marketing costs to both non-callable and non-deliverable listings.
While every marketer knows that NCOA data is fairly accurate, it can be outdated. At best, NCOA data is 30 days old, at worst, it's months out of date. Source derived telco data like M1 data is updated almost as soon as changes occur. Ask us today for a custom comparison of your existing data file against our historical data.
