Abstract: A cleanse engine receives address data from an application as the address data is entered into the application. The cleanse engine parses the address data as the data is received from the application. The cleanse engine performs a final address validation to validate a final address when sufficient parsed address data is available and returns the final address to the application. The cleanse engine sends the parsed address data to a search engine when insufficient parsed address data is available to perform the final address validation. When the parsed address data is sent to the search engine, the search engine queries reference data and returns a list of search results to the cleanse engine. The cleanse engine standardizes the list of search results from the search engine and sends the list of search results to the application.
