Starting from May 12, the official start of the campaign period, until the day before the election on June 2, anyone who is eligible to campaign may conduct electioneering by any means not restricted under the Public Official Election Act (hereinafter referred to as the "Act").

Campaign Methods Permitted for Candidates:

1. Printed Materials and Installations

The National Election Commission (NEC) will post candidate election posters in approximately 80,000 designated locations nationwide and distribute around 26 million booklet-type election bulletins and 25 million leaflet-type election bulletins to all households. The top 10 policies and pledges of each candidate can also be found on the NEC’s Policy and Pledge Platform (https://policy.nec.go.kr).

Candidates, their spouses (or one person designated by the candidate if there is no spouse), lineal ascendants or descendants, and election staff such as election campaign managers and workers who accompany the candidate may distribute the candidate’s name cards. Candidates may also prepare and distribute a written pledge document outlining their policies and implementation plans through themselves, their families, campaign managers, liaison office heads, campaign staff, and financial managers.

Candidates may hang banners within the constituency up to twice the number of towns (eup/myeon/dong) in the district. However, political parties may not promote their policies or positions on political issues using facilities during the campaign period. Thus, any banners posted by parties must be removed by May 11.

2. Public Speeches and Debates

Candidates and their campaign managers, liaison office heads, or campaign workers (hereinafter “the candidate group”), or any person designated from among those eligible to campaign, may hold speeches or debates at public locations from 7 a.m. to 11 p.m. The candidate group may also make temporary speeches at indoor events organized by others.

However, amplifying equipment for public speeches and debates may only be used from 7 a.m. to 9 p.m., and recording devices may only display visuals without audio until 11 p.m.

3. Use of Media and Online Platforms

Candidates (including their nominating parties) may advertise their party’s platform, candidate’s views, and related matters in daily newspapers, on internet news websites, and via television and radio. Candidates and their designated speakers may also deliver broadcast speeches on TV and radio.

Candidates may send campaign-related text messages—including images, voice, video, and multimedia content—through automated broadcasting systems or via service providers by email. However, the number of such messages sent by automatic broadcasting methods, including those sent as a preliminary candidate, must not exceed eight.

Electioneering Methods and Guidelines for Voters:

Eligible voters may campaign—except on election day—by verbally or by phone urging support for a specific political party or candidate. Election campaigning using the internet, email, text messages, and social media is allowed at all times, including on election day.

However, starting 90 days before the election, no one may produce, edit, distribute, screen, or post deepfake videos for campaigning purposes. Furthermore, sharing or forwarding content on social media that defames a candidate or contains false information may constitute a legal violation, so voters should exercise caution.

During the campaign period, voters may engage in electioneering by producing or purchasing small items (within 25cm in length, width, and height) at their own expense. They may also volunteer for a candidate’s campaign. However, no one may demand or receive compensation or reimbursement for such voluntary campaign activities.

The National Election Commission urged all participants to follow the law to ensure a fair and clean election, with candidates competing based on policies and voters making informed decisions based on platforms and qualifications.
