What are the possible values for the country string

We are trying to determine the possible string values that can be returned in an address object’s country field. We found the following in the constants API and are wondering if these are the only possible values.

jurisdiction:
‘england-wales’ : “England/Wales”
‘wales’ : "Wales "
‘scotland’ : “Scotland”
‘northern-ireland’ : “Northern Ireland”
‘european-union’ : “European Union”
‘united-kingdom’ : “United Kingdom”
‘england’ : “England”
‘noneu’ : “Foreign (Non E.U.)”

This is the apprvoved list you need to use when incorporating companies: Nationalities and countries for company filings - GOV.UK. However this was only introduced a couple of years ago. Prior to that I think it used standard ISO country codes: ISO - ISO 3166 — Country Codes

I expect that some time in the past when it was just paper forms it was just free text and there may not have been any validation.

There is a post on another forum that suggests at some point the data on hand was going to be “cleansed”. I’m not sure if that ever happened or will ever happen. There will be records where the country listed no longer exists on the official list and can’t be mapped one-to-one etc.

Jurisdiction (the enumeration you posted above) is a different beast.
