There are different ways you can implement this API, depending on how you want to capture your addresses. Select the best option below, and we'll point you in the right direction.
Our Typedown search type is designed to allow the user to enter the most general address elements first and, once that has been found, move on to more specific parts of the address. The suggestion list is updated a short period after the user stops typing (this period is currently 300 milliseconds). The user can drill down through a series of results to select the required address. Suggestions can be refined as the user types.
Our Intuitive search type is designed to provide accurate suggestions in real-time, that continually update as the user types. The user should provide the address elements in the order that they would appear on an envelope.
Our Singleline search type is designed to find an exact or close matching address based on two or three key address elements, entered by the user in the order as they would appear on an envelope. The suggestions can refined with additional input from the user before they select an address from the list.
Our Verification search type is designed to verify complete addresses. The user supplies a complete address, as it would appear on an envelope, in single or multiple address fields and our solution returns a fully formatted address and a level of confidence.
Our CASS search type is designed to CASS® validate and standardize complete address input with Delivery Point Validation and perform LACSLink™ processing.

Our Keyfinder search type is designed to use a search key to find the corresponding address. For example, the user enters a gas or electrical meter number, a Unique Property Reference Number (UPRN) or a Unique Delivery Point Reference Number (UDPRN) and our service will respond with the corresponding address.
Our lookup search type is designed to use a postcode to find the corresponding address.
