regionCode property

CLDR region code of the country/region.

This field may be used in two ways: 1) If telecommute preference is not set, this field is used address ambiguity of the user-input address. For example, "Liverpool" may refer to "Liverpool, NY, US" or "Liverpool, UK". This region code biases the address resolution toward a specific country or territory. If this field is not set, address resolution is biased toward the United States by default. 2) If telecommute preference is set to TELECOMMUTE_ALLOWED, the telecommute location filter will be limited to the region specified in this field. If this field is not set, the telecommute job locations will not be limited. See https://unicode-org.github.io/cldr-staging/charts/latest/supplemental/territory_information.html for details. Example: "CH" for Switzerland.
