Did you see the rumours in the final posts of some of those threads that Waze is changing the way the house number search order works? I emphasise rumour only!

Also Kaiglynn you could try using "Residential Place Points" to add your townhouse numbers and see if that works?

I don't think it is possible to add those numbers at all then.

No I think that it does work if Google Maps has no data. The rumoured update just shifts the order in which the app will look for a result. This doesn't change my view that if the Google Map data is good then there doesn't seem much point also adding it to the Waze map. (same for lots of the point places people add to the map)

No I don't think you can do that.
