  • Geocoding accuracy is dependant on geographic coverage that change from one country to another. ViaMichelin improves continuously this coverage.
  • Number of results cannot exceed 50.
  • returned locid have no meaning outside ViaMichelin services. They are not portable among other geodata suppliers. They should not be considered sustainable over time.
