Database Interface API
This API provides for XML or JSON responses for all three resolution levels we offer to subscribers.
The most economical service for companies wanting to improve efficiency while maintaining affordability. City and town names with sales tax detail are provided for every locality within a ZIP code, giving the operator the ability to choose the jurisdiction they want. ZIP Code API
A very high level of jurisdictional certainty at an affordable price. Sometimes referred to as the 9-digit ZIP code, the first 5 digits determine a delivery area, such as a town and state, and the additional 4 digits target the location to within one side of a street within a range of addresses, such as 100 to 120 East Main St. ZIP+4 API
The most accurate sales tax jurisdiction granularity for companies needing precision data. Spot-On™ validates U.S. postal address and converts street address into latitude and longitude coordinates (also known as geocoding) to provide the highest level of resolution available. Spot-On™ API
The ZIP Code API, ZIP+4 API, and Spot-On™ API pages have code samples for .XML or .JSON responses, allowing unlimited testing with addresses found within the ZIP code range from 90001 to 90999. If you would like to perform testing outside of that range, please call 866-492-8494 or e-mail us to request a free limited-time account.
