== Changing or Merging an Entire City Name ==
Using mass editing tools to change a city name on all segments is strongly discouraged
. The mass editing tools can lead to errors and loss of data. The correct procedure is to contact your Region Coordinator with the old city name, new city name and a permalink of the center of the area. The coordinator will then ask Waze to make the correction in their database. A side benefit is any polygon with the old city name will be removed at the same time . Merging two cities should also be handled the same way.
