[[File:HN_Interpolation.png|200px|thumb|right]]On road segments where Waze house numbers exist, Waze will approximate the position of 'missing' House Numbers. In the example image shown to the right, the end unit townhomes have the Waze house numbers marked, Waze will therefore approximate the location of the unmarked house numbers, roughly shown in blue.
Interpolation/extrapolation is fairly simple:
** Need to have a primary or alternate city name on the particular road segment
** Need to have at least two house numbers on affected side of the particular road segment
