Hi, since this question got added to the FAQ, addition text has been inserted into the middle of the answer:
Starting in late 2012, Waze enabled the adding of house numbers, or address data to the Waze Map Editor. The form of this is to select a segment and specify the starting and ending address numbers for that segment. This would allow Waze to figure out the actual address location by spreading the addresses evenly along the segment. This isn't optimal, but does allow Waze to resolve more address lookups internally rather than rely exclusively on external providers. In even later 2012, Waze took this system offline to work on a new system that will use pinpoints for addresses instead of address ranges. Beta testing of the feature started in January 2013 for the NA Server & February 2013 for the ROTW Server.
This paragraph appears to be misplaced, and honestly makes the whole answer confusing as its really irrelevant to the question.
I offer two suggestions for changing it:
1 - Delete the paragraph
2 - Delete the paragraph and add this line to the end of the answer "The Waze map editor currently allows for the placement and adjustment of addresses on streets, and while it is a good idea to update this address information for accuracy, it is not currently being used by Waze for navigation."
