What counts as a US Secondary Address data result?


There are two ways to use your results with US Secondary Address Data. The first way is to request a count of all the secondary addresses at a primary location. For example, if an apartment building has 100 units and you request the count, Smarty would return the count of 100 units, which would be considered one result. The second result type returns a list of all complete addresses with complete secondary components. In this case, 100 results would be used.

What happens when my US Secondary Address data subscription runs out?


When you purchase US Secondary Address Data, you'll select auto-renew in your account. We charge your card or invoice you for a new batch of results and renew your subscription starting on the current date. We do this so the service is always available for you.

How accurate is Smarty's US Secondary Address data?


US Secondary Address Data uses Smarty's US Rooftop Geocoding to ensure you get the most accurate response possible. With the joint force of geocoding and secondary address data, you gain access to the SmartyKey™. The SmartyKey is a persistent, unique identifier assigned to every address that never changes despite frequent changes in street names and other address components.
