If you prefer not to run US domestic delivery address verification through the Internet using Dial-A-ZIP, you can run address verification from the US Postal Service Address Management System (AMS) database that you install onto your hard drive from a DVD. This process uses the same USPS data that Dial-A-ZIP uses through Internet access. The use of the AMS database, which you install from a DVD, requires a subscription.
