CASS Field Descriptions An output record will contain the following:
A subset of Verify fields, with the following exception:
- For on-premises CASS, the AVC and AQI fields will be populated by a default value “Z00-Z00-Z0-000” and “Z” respectively. Customers should use the CASS output fields DPVConfirmedIndicator, DPVFootnotes, and ResultsString to determine the quality and accuracy of processed record. Loqate Cloud CASS customers will see the AVC populated.
- By design, under some conditions the CASS engine will return fields from the input address that are not from the CASS lookup, but retained from the input. In these cases, the input address includes additional information that is not in the USPS reference dataset, and not verified, but which is important for correct delivery (for example, “deliver to front desk”).
Please feel free to reach out to Loqate Support if you have any questions.
The table below displays the CASS fields currently available in the Loqate API.
