The method in which you are access data from us (bulk or API) determines how you will parse addresses.
If you are using the API, then we have built-in address parsing which will attempt to parse, standardize, and reconcile the submitted address to an address in our database. Typically we see between a 70-80% match rate across most of our clients using our API. If you are accessing our data via bulk export file delivery, then it would be up to you to build a system that can match your addresses against the properties we've supplied. We can help with some recommendations if required.
