This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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.


const paymentRegionCode = paymentAddress.regionCode;
