Due to the increasing amount of telephone numbers, telephone companies are adding many new area code/exchange combinations. Over 10,000 Area Code/exchange combinations are added to or changed annually. To improve your connection rate with your customers or prospects, it is recommended that you update your Area Codes prior to launching your telemarketing campaign.  Dirmark provides you the most comprehensive system available to keep your customers or prospect list up to date. We do this by matching the exchange and zip code combinations on your file to our database and verifying that the Area Code is correct. If the combination is deemed incorrect, the correct Area Code is then appended.

Business Telephone Append matches your customer or prospect file to our multi-sourced Business Megabase.  Charges only apply when phone is appended.
