The regionCode read-only attribute of the PaymentAddress interface returns a one-, two-, or three-alphanumeric code (DOMString) representing the region of the address (e.g., "CA" for California, or "11" for Lisbon, Portugal).
The code is derived from the ISO 3166-2 standard, which defines codes for identifying the subdivisions (e.g., states, provinces, autonomous regions, etc.) of all countries in the world.
If the browser can't determine the region code, or the country doesn't use regions for postal addresses, it returns an empty string.
var regionCode = paymentAddress.regionCode;
A DOMString indicating the one to three character alphanumeric code representing the region portion of the address. This should correspond to region, but should be the ISO 3166--2 standard's region code. The string is empty if the region code couldn't be determined, isn't needed for the address's country, or was not provided.
