Switzerland Recording Laws: All-Party Consent Rules and Penalties (2026)

How Switzerland's Recording Consent Standard Works

Switzerland is one of the strictest countries in the world when it comes to recording conversations. The law does not merely require notice or the consent of one party. It demands the express permission of every single participant before any recording takes place.

What makes the Swiss approach unusual is its treatment of participants. In many countries, a person who is part of a conversation may record it freely. Not in Switzerland. Under Art. 179ter of the Swiss Criminal Code (Schweizerisches Strafgesetzbuch, or StGB), even a direct participant commits an offense by recording without everyone else's agreement.

This all-party consent requirement applies across the board: phone calls, in-person meetings, video conferences, and voice messages. The law draws no distinction between analog and digital communication methods. If it is a private conversation and you record it without universal consent, you face criminal liability.

The framework rests on three core provisions of the StGB, supplemented by the revised Federal Act on Data Protection (nFADP) that took effect on September 1, 2023. Together, these statutes create overlapping criminal and regulatory exposure for unauthorized recording.

Art. 179bis StGB: Eavesdropping on and Recording Others' Conversations

Article 179bis targets outsiders. It prohibits any person from using a listening device to eavesdrop on a private conversation between other people, or from recording such a conversation on any recording device, without the permission of all participants.

The provision covers three distinct offenses:

1. Eavesdropping or recording. Using any device to listen in on or capture a non-public conversation that you are not part of.
2. Exploiting unlawfully obtained information. Making use of facts that you know, or should reasonably assume, came to your attention through an act of illegal eavesdropping or recording.
3. Storing or distributing illegal recordings. Keeping a recording that you know was made unlawfully, or making it available to others.

Penalty Under Art. 179bis

The penalty is a custodial sentence of up to three years or a monetary penalty. This is the harshest sentence among the recording-related provisions in the StGB. Prosecution requires a formal complaint from the affected party (Antragsdelikt).

Art. 179bis was inserted into the Criminal Code on December 20, 1968, and entered into force on May 1, 1969. Its language has proven durable because it references "listening devices" and "recording devices" broadly, covering modern technology without requiring amendments.

Art. 179ter StGB: Unauthorized Recording of Your Own Conversations

Article 179ter is the provision that sets Switzerland apart from most of the world. It makes it a criminal offense for a participant in a private conversation to record that conversation without the consent of the other participants.

In practical terms: if you are on a phone call with someone and you press record without telling them, you are committing a crime under Swiss law. The same applies to in-person conversations, video calls, and any other private exchange.

The article covers two offenses:

1. Participant recording without consent. Recording a private conversation you are part of on any recording device without the permission of the other participants.
2. Handling unlawful recordings. Storing, using, making available, or disclosing the contents of a recording that you know or should assume was made in violation of paragraph 1.

Penalty Under Art. 179ter

The penalty is a custodial sentence of up to one year or a monetary penalty, on complaint. The lower maximum sentence compared to Art. 179bis reflects the distinction Swiss law draws between a participant who records and an outsider who eavesdrops. Both are crimes, but eavesdropping by a third party is treated as the more serious offense.

Why This Matters for Foreigners and Travelers

People from one-party consent countries regularly assume they can record their own calls and meetings. In the United States, the United Kingdom, Canada, and most of the European Union, a participant generally has that right. Switzerland is an explicit exception. Ignorance of the law does not function as a defense. Anyone conducting business with Swiss counterparts or traveling to Switzerland should understand this distinction before hitting record.

Art. 179quinquies StGB: The Narrow Exceptions

Article 179quinquies provides the only statutory exceptions to the all-party consent requirement. These exceptions are tightly drawn and cover two specific situations.

Exception 1: Emergency, Rescue, and Security Services

Recording is permitted without consent when conversations involve emergency services, rescue services, or security services. Calls to police, fire departments, ambulance dispatch, and similar crisis lines may be recorded by those services without obtaining individual consent from callers.

This exception carries no restrictions on use. Emergency services may retain, review, and use the recordings as needed for their operational and investigative purposes.

Exception 2: Routine Bulk Business Transactions

Recording is permitted when telephone conversations concern orders, contracts, reservations, and similar business transactions that occur in high volume with time pressure. The Federal Data Protection and Information Commissioner (FDPIC) and Swiss courts have emphasized that this exception is narrow.

Conversations that qualify include:

• Telephone ordering services processing purchase orders
• Reservation services handling hotel, restaurant, or travel bookings
• Financial trading desks recording transaction instructions (subject to additional FINMA requirements)

Conversations that do not qualify:

• Customer complaints
• Complex contract negotiations
• Advisory or consulting calls
• Sales calls that go beyond routine order-taking
• Employee evaluations or disciplinary conversations

Purpose Limitation on Business Recordings

Even when the bulk business exception applies, recordings may only be used to secure evidence of the transaction. Using them for marketing analysis, employee training, quality monitoring, or disclosure to third parties is not covered by the exception and may violate both the StGB and the nFADP.

The nFADP: Switzerland's Revised Data Protection Law

The revised Federal Act on Data Protection (nFADP, or revDSG in German) replaced Switzerland's 1992 data protection law on September 1, 2023. While the StGB provisions address the criminal act of recording, the nFADP governs the processing of personal data that recordings contain.

A voice recording is personal data under the nFADP. Processing it, which includes collecting, storing, using, disclosing, or destroying it, must comply with the law's requirements.

Key nFADP Requirements for Recordings

Consent standards. When consent is the legal basis for processing, it must be freely given, informed, and specific. For recordings that contain sensitive personal data (such as health information, religious views, or biometric voice patterns), express consent is required.

Transparency. Anyone whose voice is recorded must be informed about the purpose of the recording, how it will be used, who will have access to it, and how long it will be stored. This obligation exists independently of the StGB consent requirement.

Data minimization. Recordings should capture only what is necessary for the stated purpose. Blanket recording of all calls or meetings without a justified basis violates the proportionality principle.

Data subject rights. Individuals have the right to request access to recordings of their voice, demand correction of inaccurate information, and require deletion when there is no legal basis for continued storage.

nFADP Penalties

The nFADP introduces criminal penalties of up to CHF 250,000 (approximately USD 280,000 or EUR 260,000 as of early 2026). This represents a dramatic increase from the previous maximum of CHF 10,000 under the old law.

A critical distinction from the EU's GDPR: Swiss data protection fines target individuals, not companies. The person directly responsible for the violation faces the fine. This means a compliance officer, department head, or executive who authorizes unlawful recording practices can be personally prosecuted.

There is a limited exception. When a fine would not exceed CHF 50,000 and identifying the responsible individual would require disproportionate investigative effort, the fine may be imposed on the company instead.

Prosecution requires willful (intentional) conduct. Negligent violations are not subject to criminal sanctions under the nFADP, though they may still trigger civil liability.

The FDPIC: Who Enforces the Rules

The Federal Data Protection and Information Commissioner (FDPIC, or EDOB in German) is Switzerland's independent supervisory authority for data protection. The FDPIC oversees compliance with the nFADP and publishes guidance on recording-related topics.

The FDPIC can investigate potential violations, issue binding orders requiring organizations to change their practices, and refer matters for criminal prosecution. However, the FDPIC does not directly impose fines. Criminal prosecutions under the nFADP are handled by cantonal law enforcement authorities.

The FDPIC maintains detailed guidance documents on its website (edoeb.admin.ch) covering specific recording scenarios, including workplace telephone monitoring and video surveillance. These guidance documents, while not legally binding in the way statutes are, reflect the FDPIC's enforcement priorities and interpretive positions.

Phone Calls vs. In-Person Conversations

The all-party consent requirement applies equally to telephone and in-person conversations, but practical considerations differ.

Phone Calls

Recording a phone call without the consent of every person on the line violates Art. 179ter (if you are a participant) or Art. 179bis (if you are an outsider intercepting the call). The Art. 179quinquies exceptions for emergency services and bulk business transactions apply only to telephone conversations.

For cross-border calls, the applicable law generally follows the location of the recording device. If you are physically in Switzerland and record a call with someone in another country, Swiss law applies to your act of recording.

In-Person Conversations

Recording a face-to-face conversation, whether at a meeting, dinner, or casual encounter, follows the same rules. All participants must consent before recording begins. Hidden microphones, concealed phones set to record, or wearable recording devices all fall within the scope of Art. 179bis and 179ter.

The exceptions under Art. 179quinquies do not apply to in-person conversations. Those exceptions are drafted with telephone communications in mind.

Video Recording

Art. 179quater of the StGB separately addresses visual recording. It prohibits the observation with cameras or the photographing and filming of facts belonging to someone's private domain. The penalty mirrors Art. 179bis: up to three years in prison or a monetary penalty. Video recordings that also capture audio trigger both 179quater and the audio recording provisions simultaneously.

Workplace Recording Rules

Switzerland places significant restrictions on workplace recording and monitoring.

Employer Monitoring of Phone Calls

Employers may not listen to or record employees' private phone calls under any circumstances. Doing so violates personality rights under the Swiss Code of Obligations (Obligationenrecht, OR) and may constitute a criminal offense under the StGB.

For business calls, employers may implement monitoring, but only with the consent of all participants and after providing clear advance notice to employees. The FDPIC has published specific guidance on this topic, requiring employers to:

• Inform employees in writing about the monitoring system in use
• Explain how the system operates
• Clarify the distinction between private and business calls
• State what employment sanctions may follow from violations
• Specify data retention periods (maximum 6 months for technical metadata)

Employee-Initiated Recording

An employee who secretly records a conversation with a supervisor, colleague, or client in Switzerland commits a criminal offense under Art. 179ter. This applies even when the employee believes they need evidence of harassment, discrimination, or other wrongdoing.

Swiss courts have addressed the tension between the recording prohibition and the need for evidence. The general rule is that recordings made in violation of Art. 179bis or 179ter are inadmissible as evidence. A narrow exception exists in criminal proceedings: illegally obtained recordings may be admitted if they are indispensable to investigating a serious crime carrying at least three years of imprisonment.

Video Surveillance in the Workplace

CCTV and video monitoring of workplaces must comply with both data protection law and the prohibition on employee health and behavior monitoring under Art. 328b of the Code of Obligations. Cameras may not be installed for the purpose of monitoring employee performance. When surveillance is justified for security purposes, employees must be informed, and the recording area must be minimized.

Recording in Public Spaces

The StGB provisions protect private (non-public) conversations. A conversation is considered non-public when participants conduct it with a reasonable expectation that it cannot be overheard by the general public without technical assistance.

Conversations held in truly public settings, where anyone passing by could overhear them, may fall outside the scope of Art. 179bis and 179ter. However, the line is not always clear. A conversation between two people at a quiet corner table in a restaurant may still qualify as non-public. A whispered exchange on a busy street could also be protected.

The Swiss Federal Supreme Court (Bundesgericht) has interpreted "non-public" broadly. The test is whether the participants had a reasonable expectation of privacy, not whether they were in a nominally public or private space.

Public CCTV Surveillance

Private individuals and businesses are generally not permitted to operate CCTV systems that monitor public property. The FDPIC's position is clear: preserving security in public areas is a police function, not a private one.

Limited exceptions exist when monitoring private property incidentally captures small portions of public space, such as a security camera covering an ATM that also captures a section of sidewalk. Storage of such recordings is typically limited to 24 to 72 hours unless a specific incident justifies longer retention.

Cantonal Considerations

Swiss criminal law, including the StGB provisions on recording, is federal law that applies uniformly across all 26 cantons. There are no cantonal variations in the definition of the offenses or in the maximum penalties.

However, cantonal authorities handle prosecution. Each canton has its own prosecution office (Staatsanwaltschaft) and courts. Procedural details, including how complaints are filed and processed, follow cantonal criminal procedure to the extent not governed by the federal Swiss Criminal Procedure Code (StPO).

Some cantons also maintain supplementary police regulations that address surveillance and recording in specific contexts, such as monitoring at public events or recording by private security firms. These do not override the federal StGB rules but may impose additional administrative requirements.

Business Compliance: What Companies Need to Know

Organizations operating in or dealing with Switzerland should build their compliance programs around the intersection of the StGB and the nFADP.

Call Recording Compliance

Step 1: Determine whether an exception applies. Only genuine bulk business transactions (orders, reservations, standardized contracts) qualify under Art. 179quinquies. Most customer service, consulting, and advisory calls do not.

Step 2: Obtain all-party consent. For any call that does not fall within a 179quinquies exception, play a clear notification at the start of the call and obtain affirmative consent from every participant before recording begins. Consent must be specific: the caller must understand that the conversation will be recorded, what the recording will be used for, and who will have access to it.

Step 3: Provide an opt-out. If a participant declines to be recorded, the call must proceed without recording. Refusing service because a customer will not consent to recording raises significant legal risk.

Step 4: Limit use and retention. Recordings may only be used for the stated purpose. Retention periods should be defined and enforced. The nFADP's data minimization principle prohibits indefinite storage without justification.

Step 5: Document everything. Maintain records of consent mechanisms, retention policies, access controls, and any data subject requests related to recordings.

Meeting and Video Conference Recording

The same principles apply to in-person meetings and video conferences. A company that records internal meetings must obtain the consent of every participant. For video conferences using platforms like Zoom, Teams, or Webex, the built-in recording notification is a starting point, but Swiss law requires actual consent, not just notice. Participants must have the opportunity to object before recording begins.

Cross-Border Considerations

Swiss recording rules apply when the recording takes place in Switzerland, regardless of where the other participants are located. A multinational company with offices in Switzerland must apply Swiss rules to any recording initiated from a Swiss location, even if the other participants are in countries with more permissive laws.

Conversely, when a person outside Switzerland records a call with someone in Switzerland, the recording may be lawful under the recorder's local law but could still give rise to claims under Swiss civil law if the recording is later used in a way that affects the Swiss participant.

Penalties Summary

The following penalties apply under current Swiss law:

Offense	Statute	Maximum Penalty
Eavesdropping on or recording others' conversations	Art. 179bis StGB	Up to 3 years in prison or monetary penalty
Recording your own conversation without consent	Art. 179ter StGB	Up to 1 year in prison or monetary penalty
Visual recording of private domain	Art. 179quater StGB	Up to 3 years in prison or monetary penalty
Violating nFADP data protection rules	nFADP Arts. 60-61	Up to CHF 250,000 fine (individual)
Workplace personality rights violation	OR Art. 328b	Civil damages

All StGB recording offenses are prosecuted on complaint (Antragsdelikt). The affected person must file a criminal complaint within three months of learning the identity of the offender. The limitation period ranges from three to seven years depending on the specific offense.

Recent Developments

The nFADP's entry into force on September 1, 2023, was the most significant recent change affecting recording practices. The 25-fold increase in maximum fines (from CHF 10,000 to CHF 250,000) and the shift to individual liability fundamentally changed the risk calculus for organizations and their employees.

Switzerland has also been debating broader surveillance powers. Proposed changes to the Ordinance on the Surveillance of Post and Telecommunications (VUPF) drew significant opposition from technology companies and privacy advocates. Critics argued that expanded state surveillance capabilities would undermine Switzerland's reputation for privacy protection. The government has indicated it will revise the proposed changes in response to public feedback.

The FDPIC continues to issue updated guidance on specific recording scenarios, and enforcement activity under the nFADP is expected to increase as the law matures and precedent develops.
