Simply the number of countries it allows you to travel to, without a visa. An American or a UK passport lets you enter 147 countries without a visa – at best, you’ll automatically get a Visa on Arrival. This is how the firm’s Passport Index website has ranked passports based on a ‘Visa Free Score’.
