A label for the place or location at which a person or organization may be reached. This class is used primarily for mailing addresses, but includes an optional County property which is often needed for statistical reporting or pricing purposes. Note that it doesn’t include a State code, as this code is added in a US-specific subtype. This is done because states or provinces for other countries will be identified in using different value-sets, if at all. The state code in the US Mailing Address sub-type is bound to a particular value set, the province code in the Canadian Mailing Address sub-type is bound to a different value set, while the Other Country Mailing Address simply contain as string for the jurisdiction. "An address expressed using postal conventions (as opposed to GPS or other location definition formats). This data type may be used to convey addresses for use in delivering mail as well as for visiting locations which might not be valid for mail delivery. There are a variety of postal address formats defined around the world." - HL7 FHIR, Address.
