Otherwise the API response will be an empty array. invalid The API will return detailed output for both valid and invalid addresses. To find out if the address is valid, check the dpv_match_code. Values of Y, S, or D indicate a valid address. enhanced The API will return detailed output based on a more aggressive matching mechanism. It also includes a more comprehensive address dataset beyond just the postal address data. Requires a US Core license or a US Rooftop Geocoding license. Note: A freeform address, that we can’t find a match for, will respond with an empty array, “[]”. Notes: (1) The invalid setting is not compatible with freeform address input.

(2) When submitting addresses in components, setting match to invalid will prevent the API from finding valid matches for ambiguous address input.
