South Korea Recording Laws: One-Party Consent Rules and Penalties (2026)

How Recording Consent Works in South Korea

South Korea is a one-party consent jurisdiction. If you are a participant in a conversation, you can record it without telling or getting permission from anyone else in that conversation. This applies to phone calls, in-person meetings, video calls, and any other form of direct communication.

The governing statute is the Protection of Communications Secrets Act (통신비밀보호법), often abbreviated as PCSA. First enacted in 1993 and amended multiple times since, the PCSA draws a sharp legal line between two categories of recording: participant recording (legal) and third-party recording (criminal).

This distinction matters for everyone in South Korea, from employees documenting workplace disputes to businesses recording customer calls. Understanding where that line falls, and what happens when you cross it, is essential.

The Protection of Communications Secrets Act (PCSA)

The PCSA is the primary law governing wiretapping, electronic surveillance, and conversation recording in South Korea. It establishes what kinds of surveillance require judicial authorization, what kinds of recording are flatly prohibited, and what penalties apply to violations.

Article 3: The Core Prohibition

Article 3 of the PCSA sets the foundation. It provides that no person shall censor any mail, wiretap any telecommunications, or record or listen to any conversation between others that is not made public, except as authorized by the PCSA itself, the Criminal Procedure Act, or the Military Court Act.

The critical phrase is "conversation between others" (타인간의 대화). The prohibition targets recordings of conversations the recorder is not part of. If you are sitting in a room secretly recording two colleagues talking to each other while you remain silent and uninvolved, you are recording a "conversation between others." That is what the law prohibits.

If you are actively participating in the conversation, the prohibition does not apply. You are not recording a conversation "between others." You are recording your own conversation.

Article 14: Electronic and Mechanical Device Restrictions

Article 14 reinforces the prohibition with specific reference to technology. It states that no person shall record a conversation between others that is not open to the public, or listen to it, through the use of electronic or mechanical devices.

This provision targets hidden microphones, bugging devices, intercepted phone lines, and similar surveillance tools used to capture conversations the operator has no part in. It does not restrict a participant from using their own phone or recording device during a conversation they are genuinely part of.

Government Wiretapping Authorization

The PCSA also governs when law enforcement and intelligence agencies may conduct wiretaps. Court authorization is required in most cases, with defined procedures for requesting and reviewing surveillance orders. The January 2025 amendment (Act No. 20735), which took effect on August 1, 2025, strengthened the legal framework around government access to communications data, reinforcing judicial oversight of state surveillance.

Supreme Court Precedent on Participant Recording

The Supreme Court of South Korea has addressed participant recording directly, and its rulings have solidified the one-party consent framework.

The 2002 Ruling: Participant Recording Is Not a Crime

In a landmark October 2002 decision, the Supreme Court held that it is not illegal for a party to a phone call to record the conversation secretly without the other party's knowledge. The court reasoned that because the PCSA prohibits recording conversations "between others," a participant who records their own conversation falls outside the scope of the prohibition.

This ruling established the baseline rule: if you are in the conversation, recording it does not violate the PCSA. The same analysis applies regardless of the number of participants. In a group conversation of five people, any one of those five may record without the consent of the other four.

The 2024 Admissibility Ruling: Privacy Limits

In January 2024, the Supreme Court issued a more nuanced decision involving a parent who placed a recording device in their child's backpack to capture a teacher's remarks in a classroom. The court ruled the recording inadmissible.

The reasoning: the parent was not a participant in the classroom conversation. The teacher's remarks were directed at students, not at the parent. Because the parent was a third party, the recording fell under the Article 3 prohibition on recording "conversations between others." Even though the parent's intent was to document suspected child abuse, the recording lacked evidentiary value under the PCSA.

This ruling demonstrated that good intentions do not override the participant requirement. The law asks a simple question: were you in the conversation? If not, the recording is illegal regardless of your reasons for making it.

Admissibility of Legal Recordings

Recordings made lawfully by a conversation participant are generally admissible as evidence in South Korean courts. In civil proceedings, courts have broad discretion to accept participant recordings under the principle of free deliberation (자유심증주의). In criminal cases, the Criminal Procedure Act (Article 308-2) excludes evidence obtained in violation of due process, so an illegally obtained recording would be barred. A lawfully obtained participant recording, however, clears this threshold.

One important qualification: the Supreme Court has indicated that even a lawfully obtained recording could be denied admissibility if it significantly invades personal privacy or dignity. This is a narrow exception, but it signals that courts will weigh privacy interests even when the recording itself was technically legal.

The Failed 2022 All-Party Consent Bill

South Korea's one-party consent framework has not gone unchallenged. In August 2022, Rep. Yoon Sang-hyun of the ruling People Power Party introduced a bill that would have required consent from all parties before a conversation could be recorded.

What the Bill Proposed

The initial version of the bill imposed penalties of 1 to 10 years in prison for recording any conversation without the consent of all participants. This would have effectively converted South Korea from a one-party consent jurisdiction to an all-party consent jurisdiction, criminalizing the very act of participant recording that the Supreme Court had declared lawful.

Yoon had a personal stake in the debate. He had previously been embarrassed when a recorded phone call containing inflammatory remarks was leaked publicly.

Public Backlash

The bill triggered immediate and strong public opposition. A Realmeter poll of 503 adults found that 64.1% opposed the bill, while only 23.6% supported it. Opposition was especially strong among younger respondents and those identifying as politically liberal or neutral.

Critics argued the bill would strip vulnerable people of a crucial self-protection tool. Labor rights advocates pointed to cases where secretly recorded conversations had exposed workplace bullying, wage theft, and verbal abuse by employers. Victims' rights groups warned that requiring all-party consent would make it nearly impossible to document harassment, since asking a perpetrator for permission to record defeats the purpose.

Moon Sung-ho, the spokesperson for the People Power Party itself, publicly criticized the bill on social media, calling it "a dangerous law" and questioning whether it protected victims or criminals.

Withdrawal

Facing sustained opposition from the public, legal experts, and members of his own party, Yoon attempted to revise the bill. The revised version proposed fines instead of imprisonment and included exemptions for whistleblowing and corruption reporting. But the damage was done. By December 20, 2022, the bill was withdrawn entirely.

As of 2026, no similar legislation has been reintroduced. South Korea remains a one-party consent jurisdiction.

Phone Call Recording Rules

Recording phone calls in South Korea follows the same one-party framework that governs all conversation recording.

Personal Calls

If you are a party to a phone call, you may record it without telling the other person. This applies to calls made on mobile phones, landlines, and internet-based calling apps like KakaoTalk, LINE, or any VoIP platform. No notification tone, beep, or verbal disclosure is required.

Business and Call Center Calls

Businesses that record customer calls operate under the one-party consent rule for the recording itself. Because the business is a party to the call, the PCSA permits the recording.

However, the Personal Information Protection Act (PIPA) introduces additional requirements for businesses. Voice recordings contain personal data, and PIPA requires businesses to have a valid legal basis for collecting and processing that data. In practice, most South Korean call centers play an automated disclosure at the start of the call informing the customer that the conversation will be recorded. This is driven by PIPA data protection requirements rather than by PCSA consent requirements.

Businesses must also comply with PIPA rules on data retention, access rights, and purpose limitation. Recordings cannot be kept indefinitely and must be stored securely.

In-Person Recording

Face-to-face conversation recording follows the same one-party rule. If you are physically present and participating in a conversation, you may record it.

This covers meetings, negotiations, interviews, and any other scenario where you are an active participant. You do not need to announce that you are recording, place your recording device in plain sight, or obtain anyone's agreement.

The critical factor remains participation. If you leave a recording device running in a conference room and then exit before the conversation begins, you are no longer a participant when the recording captures the discussion. That turns you into a third party, and the recording becomes illegal.

Workplace Recording

Workplace recording is one of the most common real-world applications of South Korea's one-party consent rule, and it is an area where the law has significant practical impact.

Employees Recording Employers

An employee who participates in a conversation with a supervisor, HR representative, or colleague may lawfully record that conversation. This includes performance reviews, disciplinary meetings, salary negotiations, and informal discussions. South Korean labor courts have accepted participant recordings as evidence in disputes over wrongful termination, harassment, and unpaid wages.

The 2022 recording ban bill drew its strongest opposition from workplace contexts. Labor advocates argued that employees are often the weaker party in employment relationships, and that the ability to document conversations without advance warning is one of the few effective tools available to workers facing mistreatment.

Employer Monitoring of Employees

Employers may install CCTV cameras in the workplace, but PIPA requires that employees be informed in advance. Secret surveillance without notice is not permitted except as part of a law enforcement investigation authorized under separate legal authority.

If a CCTV system records audio in addition to video, the more stringent PCSA conversation recording rules apply. An employer who captures audio of employee conversations without being a participant in those conversations risks violating Article 3.

CCTV footage must be stored for a limited period. PIPA recommends a maximum of 30 days unless longer retention is justified by a specific legal, business, or security need.

Recording in Public Places

Recording in public spaces in South Korea is generally permitted. Streets, parks, and other open areas are treated as environments where there is a reduced expectation of privacy.

Photographing or filming in public does not, by itself, violate the PCSA. The law's conversation recording provisions target private, non-public conversations. A conversation held openly in a public park, loud enough for passersby to hear, is not afforded the same protection as a whispered conversation in a private office.

However, South Korea has strict laws against illegal filming of persons (몰래카메라, or "molka"). The Act on Special Cases Concerning the Punishment of Sexual Crimes criminalizes filming another person's body without their consent in a manner that could cause sexual humiliation. Penalties include up to 7 years in prison or fines up to 50 million won. This law addresses a different concern from conversation recording, but it is an important boundary on public recording behavior.

PIPA: Data Protection for Voice Recordings

The Personal Information Protection Act (개인정보보호법, or PIPA), enforced by the Personal Information Protection Commission (PIPC), is South Korea's comprehensive data privacy law. It applies to any organization or individual that processes personal data, and voice recordings fall squarely within its scope.

Voice Recordings as Personal Data

PIPA defines personal data as any information that identifies or can identify a natural person. A voice recording of a recognizable individual qualifies. This means that collecting, storing, sharing, or otherwise processing voice recordings triggers PIPA obligations.

Consent and Legal Basis

Before processing personal data, PIPA requires a valid legal basis. The most common bases include:

• Consent from the data subject, which must be specific, informed, and freely given.
• Contractual necessity, where the processing is required to perform a contract.
• Legal obligation, where processing is mandated by law.
• Legitimate interest, added in the 2023 PIPA amendments, allowing processing where the controller's legitimate interest outweighs the data subject's rights.

For businesses that record customer calls, the PCSA permits the recording on one-party consent grounds, but PIPA requires a separate justification for storing and processing the recorded data.

PIPA Penalties

PIPA violations carry serious consequences. Criminal penalties include up to 5 years in prison or fines up to 50 million won for serious offenses such as providing personal information to third parties without consent. Administrative fines can reach 5% of relevant revenue, and the March 2026 amendments (effective September 2026) will raise the ceiling to 10% of total turnover for repeat serious violations or incidents affecting 10 million or more data subjects.

The PIPC has ramped up enforcement in recent years, and businesses that collect voice recordings without documented consent, proper notice, or defined retention periods face real regulatory risk.

Penalties for Illegal Recording in South Korea

The penalty structure under the PCSA is severe by international standards.

Violation	Law	Penalty
Recording a conversation between others (third-party recording)	PCSA Article 16	1 to 10 years imprisonment; suspension of qualifications up to 5 years
Wiretapping telecommunications without authorization	PCSA Article 16	1 to 10 years imprisonment; suspension of qualifications up to 5 years
Disclosing or leaking contents of illegally recorded conversations	PCSA Article 16	Criminal punishment (imprisonment or fines)
Illegal filming of a person (molka)	Act on Special Cases Concerning Sexual Crimes	Up to 7 years imprisonment or fine up to 50 million won
Processing voice data without legal basis under PIPA	PIPA	Up to 5 years imprisonment or fine up to 50 million won
Employer installing secret audio surveillance	PCSA + PIPA	Criminal and administrative penalties

The 1 to 10 year prison range for third-party recording is notably harsh. It places the offense in the same penalty bracket as serious violent crimes, reflecting the weight South Korean law places on communications privacy.

Business Compliance Checklist

Organizations operating in South Korea that record conversations or handle voice data should take the following steps.

Confirm your participant status. The PCSA permits recording only when the recorder is a genuine participant. A business recording customer calls through its employees satisfies this requirement. A business deploying hidden listening devices to capture conversations it is not part of does not.

Establish a PIPA legal basis. Even though the PCSA allows participant recording, PIPA requires a documented legal basis for collecting and processing the resulting personal data. Identify whether you rely on consent, contractual necessity, legal obligation, or legitimate interest.

Provide notice to customers and employees. Best practice in South Korea is to inform individuals that a recording is being made, even when one-party consent makes notification legally unnecessary under the PCSA. Notice supports PIPA transparency obligations and reduces dispute risk.

Define retention periods. Recordings must not be kept longer than necessary for their stated purpose. Establish clear retention policies and automate deletion when the retention period expires.

Restrict access. Limit access to stored recordings to personnel with a documented business need. Maintain logs of who accesses recordings and when.

Train employees. Staff who handle recordings should understand what constitutes lawful recording, the prohibition on sharing recordings of others, and the data protection obligations under PIPA.

Prepare for data subject requests. PIPA gives individuals the right to access, correct, and delete their personal data, including voice recordings. Build processes to respond to these requests within the legally required timeframe.
