Hi @tanst_844288 ,
Unfortunately, the answer is no. The person column doesn't have a Country property.
But you could use Office365Users connector to get their countries.
AddColumns(LIST214,"Test_Country",Office365Users.SearchUser({searchTerm:ThisRecord.Test_Person.Email}).Country)
//LIST214 is the name of my list. Test_Person is the person column .
In other words, you could get the country by using the unique email .
Then you could use Distinct function to get unique countries array.
But before that, you should make sure to set each user's country information.
Their information is stored in azure AD.
Best Regards,
