Compiled data is as accurate as the original sources used to gather it. Current information on consumers, businesses, or executives is merely transposed from the most recent sources and is assumed accurate according to those sources. Because of this, list compilers do not guarantee accuracy of the data or usage results from it. Average turnaround time to receive, process, fulfill, ship, and deliver a list order is seven to ten working days. Lists can be rented for one time use, two time use, or one-year unlimited use.
Some formats automatically require that lists be purchased for one-year unlimited use.
There are hundreds of separate files stored at an outside order fulfillment center. The fulfillment center would actually have to schedule computer processing time, have a computer operator retrieve the particular file archive tape from the tape library, load the tape onto the computer, program the job requirements based upon the prospect's customer specifications, and produce an order in the exact format requested. Portions of simultaneous produced orders for other clients may be copied and faxed to prospective clients provided that the file and the specifications are the exact same as requested. The typical list industry minimum order is 5,000 names.
