A string specifying the top-level administrative subdivision within the country in which the address is located. This region has different names in different countries, such as: state, province, oblast, prefecture, or county.

Usage notes

In some countries, like Belgium, it's uncommon for people to provide a region as part of their postal address. In such cases, the browser returns an empty string as the value of region. However, the address should still be acceptable to use for its intended purpose (e.g., to ship a product). However, always verify addresses to make sure what the user provides is usable.
