What We Found

The claim that the United States is the only country that allows mail-in voting is false. Numerous countries around the world utilize various forms of mail-in or postal voting systems, with many allowing all citizens to vote by mail.

Evidence

The assertion that the United States is the only country in the world that uses mail-in voting is factually incorrect. According to data from the International Institute for Democracy and Electoral Assistance (International IDEA), at least 34 countries or territories allow some form of mail-in voting. Of these, approximately 12 countries—including Canada, Germany, New Zealand, and South Korea—permit all citizens to vote by mail in their elections. While the specific implementation, security measures, and accessibility of mail-in voting vary significantly between nations, the existence of these systems in other countries directly contradicts the claim that the U.S. is unique in this practice.

What's Missing or Misleading

The claim ignores the widespread international use of postal voting systems and fails to acknowledge that many other democracies have long-standing, established procedures for mail-in ballots.
