B2E's Telephone Append program assigns a confidence level to each record, based on the match between our and your national demographic files. Clients may select a maximum confidence level to meet their needs.  Matching items can include first name or first initial, middle initial, street name, house or apartment number, and zip code. To be considered a match, records must match last name (or phonetic last name) and the city. Does your prospect list only contain phone numbers without addresses?  Did your direct marketing campaign start with telemarketing and now you want to follow-up with a direct mail piece?  Simply give us your list of customer or prospect phone numbers; we can do a reverse telephone append and return the address and occupant name for direct mail purposes.   Ensure your customers receive the mailing you sent. By simply having a customer telephone number, we are able to locate as detailed of a mailing address as you prefer.
