I wish I could block all calls from UK. Since brexit all spam calls that comes through are from there sadly

So true! Area codes (and first three digits) used to indicate where you were. Now, more often than not, they indicate where you bought your first cell phone, i.e. where you lived around the year 2000 for us oldsters.

It was closer to 50% for me since there were two (overlaid) exchanges in my neighborhood. I still remember about a dozen phone numbers of friends from when I was growing up.
