There are similar problems with phone numbers. Google's libphonenumber,
for example, will tell you that +1 855 266 7269 is in the US. It's not,
it's Canadian. It appears that for any NANP "area code" that isn't
assigned to a particular place libphonenumber just says "it's in the US"
instead of "it's in one of the NANP countries".

They appear to have a similar bug with Russia/Kazakhstan.
