Wisconsin Phone Call Recording Laws: Consent Rules for All Call Types (2026)

Wisconsin is a one-party consent state, meaning you may legally record any phone call you are a party to without notifying the other participants. Wis. Stat. 968.31 governs this rule and applies to landline calls, cell calls, and VoIP conversations alike.

Recording phone calls in Wisconsin is straightforward under the state's one-party consent law. Wis. Stat. 968.31 allows you to record any telephone call, video call, or VoIP conversation you participate in without telling the other party. This applies to personal calls, business calls, and calls with government agencies.

This guide covers every aspect of phone call recording in Wisconsin, including interstate calls, business call recording, VoIP and video conferencing, and the penalties for illegal interception.

The Basic Rule: One-Party Consent

How It Applies to Phone Calls

Under Wis. Stat. 968.31(2)(b), it is legal to intercept a wire, electronic, or oral communication if one party to the communication consents. For phone calls, this means:

• You can record any call you are on. You are the consenting party.
• You do not need to announce you are recording. No verbal notice, beep tone, or written agreement is required.
• You cannot record other people's calls. Installing software or hardware to intercept calls between other people is illegal.
• Your intent matters. You cannot record for the purpose of committing a criminal or tortious act.

Types of Calls Covered

Wisconsin's one-party consent rule applies to all forms of telephone communication:

Recording Personal Phone Calls

Everyday Scenarios

Wisconsin residents commonly record personal phone calls for many practical reasons:

• Customer service calls. Recording calls with insurance companies, utility providers, banks, and other businesses helps preserve details of promises, agreements, or disputes.
• Calls with contractors or service providers. If a plumber, electrician, or contractor makes verbal promises about pricing or timelines, a recording provides documentation.
• Calls with government agencies. Recording calls with the Wisconsin Department of Revenue, DMV, or other state agencies can help you keep an accurate record of instructions or decisions.
• Legal consultations. You can record calls with your own attorney (though attorneys may have their own policies about recording).
• Personal disputes. Recording threatening or harassing phone calls can provide evidence for a restraining order or criminal complaint.

Recording Apps and Tools

Several methods exist for recording phone calls on your personal device:

• Built-in phone recording features. Some Android phones include native call recording functionality.
• Third-party recording apps. Apps available for both iOS and Android can record calls, though iOS restrictions may limit some functionality.
• External recording devices. Standalone digital voice recorders with phone adapters can capture both sides of a conversation.
• VoIP service features. Many VoIP services include built-in recording options.

Regardless of the method you use, ensure the recording captures both sides of the conversation clearly for it to be useful as evidence.

Recording Business Phone Calls

Employer Rights and Obligations

Wisconsin businesses can record phone calls under the one-party consent rule. Common business uses include:

• Quality assurance. Monitoring customer service calls to evaluate employee performance.
• Training. Using recorded calls as training materials for new employees.
• Compliance. Recording calls to ensure regulatory compliance in industries like financial services, healthcare, and insurance.
• Dispute resolution. Preserving records of verbal agreements, orders, and customer complaints.
• Legal protection. Documenting conversations that may be relevant to potential litigation.

Best Practices for Business Call Recording

While Wisconsin law does not require businesses to announce call recording, many businesses choose to provide notice for several reasons:

• Interstate compliance. If the business receives calls from two-party consent states, providing notice ensures compliance with the stricter law.
• Customer trust. Informing callers builds trust and transparency.
• Regulatory requirements. Certain industries (such as financial services under SEC and FINRA rules) may have separate recording notification requirements.

Common methods of providing notice include:

• Automated announcement at the beginning of the call ("This call may be recorded for quality assurance and training purposes")
• Written disclosure in contracts or terms of service
• Website privacy policy disclosures

The Business Extension Exception

Federal law under 18 U.S.C. 2510(5)(a) includes an exception for telephone equipment used "in the ordinary course of business." This allows businesses to monitor calls on their own phone systems when done for legitimate business purposes. This exception works alongside Wisconsin's one-party consent rule to give businesses broad authority to record business calls.

Interstate Phone Call Recording

The Interstate Call Problem

One of the most important considerations for Wisconsin residents is what happens when you call someone in a state with stricter recording laws. When a call crosses state lines, the recording laws of both states may apply.

States With Stricter Laws

If you are calling someone in any of these states, the stricter all-party consent law typically applies:

The Illinois Border Issue

Because Wisconsin shares a long border with Illinois, the interstate recording issue comes up frequently. Illinois is an all-party consent state under 720 ILCS 5/14-2, which means recording a call with someone in Illinois without their knowledge could violate Illinois law, even if you are calling from Wisconsin.

Best practice for Wisconsin-Illinois calls: Inform the Illinois party that you are recording, or get their explicit consent before beginning the recording.

Which State's Law Controls?

There is no definitive federal rule about which state's law applies to interstate calls. Courts have taken different approaches:

• Some courts apply the law of the state where the recording is made
• Some courts apply the law of the state where the non-consenting party is located
• Some courts apply the stricter of the two states' laws

The safest approach is always to comply with the stricter state's requirements when making interstate calls.

VoIP and Video Call Recording

How Wisconsin Law Applies to VoIP

VoIP (Voice over Internet Protocol) calls are treated the same as traditional phone calls under Wisconsin law. Wis. Stat. 968.27 defines "electronic communication" broadly enough to encompass VoIP transmissions. The one-party consent rule applies.

This covers calls made through:

• Zoom
• Microsoft Teams
• Google Meet
• Skype
• WhatsApp
• FaceTime (audio)
• Discord
• Slack calls
• Any other internet-based calling platform

Video Conferencing With Multiple Participants

When recording a video conference with participants from multiple states, the recording laws of all participants' states may apply. If any participant is in a two-party consent state, you should either:

• Announce at the beginning of the call that the session will be recorded
• Use the platform's built-in recording notification (Zoom, Teams, and Meet all notify participants when recording begins)
• Obtain consent from all participants before activating recording

Most business video conferencing platforms now include automatic notification features that alert all participants when recording is active. Using these features helps ensure compliance across state lines.

Platform-Specific Recording Features

Most major video conferencing platforms have built-in recording features:

• Zoom notifies all participants when recording starts and provides a consent prompt for cloud recordings
• Microsoft Teams displays a recording banner visible to all participants
• Google Meet announces when recording begins and requires the host to start recording
• Webex provides recording notifications and can restrict recording to hosts only

Using these built-in features provides an additional layer of compliance because all participants receive notice.

Federal Law and Phone Call Recording

The Federal Wiretap Act

The federal Wiretap Act (18 U.S.C. 2511) follows a one-party consent standard, consistent with Wisconsin law. Under federal law, it is legal to intercept a wire, oral, or electronic communication if one party to the communication consents, unless the interception is for the purpose of committing a criminal or tortious act.

Federal penalties for illegal wiretapping include up to five years in prison. Civil remedies under 18 U.S.C. 2520 provide statutory damages of $10,000 per violation, actual damages, punitive damages, and attorney fees.

FCC Regulations

The Federal Communications Commission (FCC) has issued guidance on phone call recording. Note: 47 C.F.R. § 64.501, which formerly required carriers to inform customers of call recording, was removed from the Code of Federal Regulations in 2017 and is no longer in force. The FCC's current call-recording guidance (FCC 24-24) governs beep-tone and disclosure requirements at the carrier level and does not override Wisconsin's one-party consent law for individual callers or businesses.

Penalties for Illegal Phone Call Recording

Criminal Penalties

Illegally intercepting phone calls in Wisconsin is a Class H felony under Wis. Stat. 968.31:

Civil Liability

Under Wis. Stat. 968.31(2m), victims of illegal phone call interception can sue for actual damages (minimum $100 per day or $1,000, whichever is higher), punitive damages, and attorney fees.

Using Phone Call Recordings as Evidence

Admissibility in Wisconsin Courts

Phone call recordings made legally under one-party consent are generally admissible in Wisconsin courts. To use a recording as evidence:

• Authenticate the recording by testifying about when, where, and how it was made
• Demonstrate that the recording has not been altered
• Show that the recording is relevant to the matter at issue
• Be prepared to address hearsay objections (many exceptions apply to recorded statements)

Preserving Phone Call Recordings

For maximum evidentiary value:

1. Save the original file without editing
2. Note the date, time, and participants immediately after the call
3. Back up the recording to cloud storage and a separate device
4. Do not share the recording on social media before legal proceedings
5. Keep a log of all recorded calls with dates and summaries
