Is there a listing for country codes included in the SafeGraph dataset?

#safegraphdata Is there a listing for country codes included in the SafeGraph dataset? I am trying to identify which countries are included (i.e. visitor_country_of_origin) aside from the US, Mexico, and Canada.

According to the docs they are ISO 3166-1 alpha codes. Places | SafeGraph Docs

Seamus is correct, the codes are ISO3166-1 alpha codes, but as far as I am aware, the only countries included are the US and Canada (CA), for both the places and patterns dataset
