Previously, for performance reasons, house number (or unit number in the case of US Address - Single House Subaddress style) was not used in suggestions' capability. The implications of this is that, while house numbers are displayed in generated suggestions, they are not validated until a Geocoding request is sent. Therefore, if the house number typed by the user does not exist, it will be displayed in suggestions but will not be returned from Geocoding results. A best practice when creating a custom locator with suggestions enabled is to create a Composite Locator with at least a Street Address or Point Address locator and a separate Street Name locator. Doing so will ensure that if the house number doesn't exist in the Street Address or Point Address locator, you'll get a fallback match to Street Name. Please note that the the maximum number of participating address locators in a composite locator is 30, but it is recommended not to use more than 10, otherwise geocoding may be significantly slower. I hope this sheds a light on this issue and gives the users a little more flexibility in reducing the ghost addresses being generated in the suggestions drop-down list until we address this issue permanently. Thank you,
