Do European Countries Really Ban Mail-In Voting? What the Data Shows

As debates surrounding election administration and ballot access continue to polarize American politics, commentators and politicians frequently look abroad for comparison. A common talking point, repeated by former President Donald Trump and various conservative commentators, claims that "almost all" European countries have banned mail-in voting due to fears of fraud. To evaluate this claim, it is necessary to look past the political rhetoric and analyze the actual electoral laws of European democracies.

The data reveals a highly fragmented landscape: while some major European nations do restrict or prohibit domestic mail-in voting for residents, others rely on it as their primary voting channel. Furthermore, the broader administrative context—specifically universal voter ID and state-run automatic voter registration—makes direct comparisons between European and American voting systems highly misleading.

The Historical Precedent: Where Postal Voting is Restricted

The talking point's strongest piece of evidence is France. In 1975, France passed Law 75-1239, which abolished postal voting for resident citizens [1]. The ban was enacted by the French National Assembly following severe instances of electoral fraud in Corsica, where local political machines were found to have bought, stolen, or fabricated postal ballots [1]. Since then, resident French citizens have been required to vote in person at their designated polling station. To accommodate voters who cannot attend in person, France allows "proxy voting" (vote par procuration), where a voter can authorize another registered voter in their municipality to cast their ballot in person on their behalf [1].

Similarly, Italy does not allow resident citizens to vote by mail. All voting within Italy must be done in person, typically using paper ballots stamped at the polling station. Other nations, such as Belgium, the Netherlands, and Romania, restrict postal voting to citizens living abroad, requiring in-country residents to vote in person or via proxy [5].

Crucially, even the countries that ban or restrict domestic postal voting still allow their citizens living abroad to vote by mail or via secure internet voting to ensure they are not disenfranchised [5]. For example, France permits remote internet and postal voting for its citizens abroad in national assembly and presidential elections, illustrating that remote voting is not viewed as inherently unsecurable.

Where Mail-In Voting is the Standard

Contradicting the assertion of a universal European ban, several of the continent's most stable and populous democracies use postal voting extensively, often on demand without requiring a specific excuse.

Germany: Postal voting (Briefwahl) was introduced in 1957 to ensure that elderly, disabled, or traveling citizens could exercise their right to vote [2]. Since 2008, German voters have been able to request a postal ballot without providing any reason. Rather than being banned, the practice has grown rapidly. In the 2021 federal Bundestag election, according to the German Federal Returning Officer (Die Bundeswahlleiterin), a record 47.3% of all ballots cast were submitted by mail, up from 28.6% in 2017 [2].

Switzerland: In Switzerland, postal voting is the dominant voting method. The Swiss Federal Chancellery standardized postal voting across all cantons by 2006 [3]. Today, voters in cantons like Zurich and Geneva automatically receive their ballots and voting materials by mail before every election or referendum. Voters can choose to return their ballots by post, drop them in a local mailbox, or vote in person. According to Swiss government statistics, over 90% of Swiss voters choose to cast their ballots by mail rather than visiting a polling station in person [3].

United Kingdom: In Great Britain, postal voting on demand has been legal since the Representation of the People Act of 2000 took effect in 2001 [4]. Voters do not need to provide an excuse to receive a postal ballot. In the 2024 general election, the UK Electoral Commission reported that approximately 20% of all votes were cast by mail, a stable proportion that has helped manage polling station lines [4].

Austria: Austria introduced nationwide postal voting (Briefwahl) in 2007 [7]. Any Austrian citizen can request a voting card (Wahlkarte) to vote by mail in presidential, parliamentary, and European elections. Approximately 15% to 20% of the Austrian electorate routinely utilizes postal voting [7].

The Full Picture: Systemic and Administrative Nuance

To fully understand the divergence in voting laws between the United States and Europe, one must examine the institutional structures that underpin their respective systems. The debate cannot be reduced to simple "access" versus "security" without accounting for two critical differences: voter registration and national identity cards.

1. State-Led Automatic Voter Registration: In the United States, voter registration is largely the responsibility of the individual, requiring citizens to navigate state-specific rules, deadlines, and forms. In contrast, almost all European countries utilize a system of automatic, state-led voter registration [5]. Municipalities maintain continuous population registers. When a citizen turns 18 or moves to a new address, their registration is updated automatically based on tax or residency records. Consequently, the registration hurdles that spark intense debate in the U.S. do not exist in Europe; eligible citizens are automatically registered and sent polling information.

2. National Identity Cards: In the U.S., the requirement to show photo identification at the polls is highly contentious, as an estimated 7 to 29 million citizens lack a valid government-issued photo ID, such as a driver's license [9]. In Europe, however, voter ID is standard and uncontroversial because almost all European countries issue standard national identity cards to all citizens, often for free or at a nominal fee [5]. Because every citizen has ready access to a standardized, government-issued photo ID, showing identification at the polling place is viewed as a routine administrative step rather than a barrier to access.

3. Security and Mail-in Protocols: European countries that allow postal voting maintain strict protocols to prevent fraud. For instance, in the United Kingdom, postal voters must provide a sample signature and date of birth when applying for a postal vote, which are then compared using automated software against the identifiers submitted on the ballot return envelope [4]. In Spain, a voter must show a national identity card in person at a post office both when requesting a postal ballot and when sending the completed ballot back [6]. These security protocols are designed to address the vulnerabilities of remote voting without banning the practice entirely.

Conclusion

The claim that European countries ban mail-in voting is a selective reading of electoral history. While France did outlaw domestic postal voting in 1975 following localized fraud, and Italy restricts the practice to citizens abroad, Europe is far from having a unified ban. Major democracies—including Germany, Switzerland, the United Kingdom, and Austria—allow postal voting on demand, with Switzerland conducting nearly its entire electoral process through the mail.

Ultimately, the comparison between U.S. and European voting laws reveals that the two systems operate under fundamentally different frameworks. Europe's standard requirement for voter ID is paired with a state-run registration system and universal access to government identity documents. When analyzing ballot security, the data suggests that European nations have chosen diverse paths: some have restricted mail-in voting in favor of in-person or proxy voting, while others have successfully secured and expanded postal voting to make participation as convenient as possible.
