The street address can be entered free-form and the closest match will be returned. This means that you could enter in a partial address (ex. '5280 Alkire') and the closest full address will be returned (ex. '5280 S. Alkire St., Littleton, CO 80127, United States'). This is done using the Google Maps service, so it takes into account your current public IP address when returning its best guess.
When validating the address, audio|acacia will return back with a formatted address and map. If the formatted address and map are wrong, you should go back and try being more specific.
If you are receiving an invalid address error, it may be because you are not providing a specific enough address (e.x. 'Basement') or that the address is unknown at this time. If you still receive an error, you should contact Support.
