Is it legal to record phone calls in Idaho?
Yes, generally. Idaho is a one-party consent state: you may record a phone call you take part in without telling the other person, because your own consent satisfies the rule. Recording calls you are not part of is illegal. When the other person may be in an all-party consent state like California or Florida, disclose the recording anyway.
What Idaho law says
Idaho follows one-party consent for phone calls, consistent with the federal Wiretap Act: as long as one participant — and you count — consents, the recording is lawful. The rule covers conversations you participate in; intercepting other people’s calls remains a crime. Bear in mind the rule protects you within Idaho — interstate calls can implicate stricter states’ laws, which is why professionals default to disclosure.
Idaho is a one-party consent state: you may record or intercept a wire, electronic, or oral communication if you are a party to it or have the prior consent of at least one participant. Secretly recording calls you are not part of is a felony. Oral communications are protected only when the speaker has a reasonable expectation of privacy.
"It is lawful under this chapter for a person not acting under color of law to intercept a wire, electronic, or oral communication where such person is a party to the communication or where one (1) of the parties to the communication has given prior consent to such interception unless such communication is intercepted for the purpose of committing any criminal or tortious act in violation of the constitution or laws of the United States or of the state of Idaho." — Idaho Code § 18-6702(2)(d)
Idaho's § 18-6702(2)(d) mirrors federal one-party consent under 18 U.S.C. § 2511(2)(d). A recording lawful under Idaho law is generally lawful under federal law too, and vice versa for participant recordings. Federal law does not preempt Idaho's felony penalties or civil remedies for illegal interception, and Idaho's constitution can impose additional limits on government surveillance beyond the federal floor.
Idaho's rule is straightforward one-party consent under § 18-6702(2)(d). If you are on the call, your own consent is enough — no announcement, beep, or permission from the other side is required. A third party may record with one participant's prior consent, which is why confidential informants and investigators routinely wear wires. Consent need not be in writing. The act only covers oral communications made with a reasonable expectation of privacy, so conversations in public where privacy is not reasonable fall outside the statute entirely. Idaho separately criminalizes disclosing or using a communication you know was illegally intercepted (§ 18-6702(2)(c)), so passing along someone else's illegal recording carries its own felony exposure. The Idaho Supreme Court has held that pen registers and trap-and-trace devices can constitute searches under the state constitution, tightening law-enforcement procedures but not changing the private one-party rule for participants.
| Consent rule for phone calls | One-party consent |
| Recording calls you're part of | Allowed — your own consent is sufficient. |
| Calls with people in other states | The stricter state's rule may apply — when in doubt, disclose. |
What breaking the law costs in Idaho
Illegal interception, recording, or disclosure is a felony punishable by up to five years in prison and a fine up to $5,000. Video voyeurism under § 18-6609 carries up to five years and a $50,000 fine when committed for sexual gratification in areas with a reasonable expectation of privacy.
Yes — § 18-6709 provides a private right of action for actual and punitive damages, plus attorney fees and costs. Liquidated damages are at least $100 per day of violation or $1,000, whichever is greater.
Exceptions worth knowing
- One-party consent: any party to the communication, or anyone with one participant's prior consent (§ 18-6702(2)(d))
- Oral communications with no reasonable expectation of privacy
- Law enforcement interception under court order or statutory emergency authority
- Communication common carriers and service providers acting in the normal course of business (§ 18-6702(2)(a))
- Law enforcement, fire, or ambulance employees who are parties to a communication and record incoming calls in the scope of employment (§ 18-6702(2)(g))
How Idaho courts have ruled
Statutes set the rule; cases show how it plays out when a recording ends up in front of a judge. These are real, decided cases under Idaho law.
What happened: Police installed a pen register on a suspect's phone line and used the information to obtain wiretap orders; Thompson moved to suppress recordings made from the wiretap.
The ruling: The Supreme Court held that using a pen register is a search under Article I, § 17 of the Idaho Constitution, suppressed the pen-register evidence, and found no probable cause for the wiretap orders without it.
What happened: Plaintiffs sued after their cordless telephone conversation was intercepted and published; they argued cordless calls are protected wire communications under the Idaho interception act.
The ruling: The court analyzed whether cordless-phone transmissions qualify as protected wire communications under § 18-6701 and addressed the scope of civil liability for interception and disclosure.
What happened: A father recorded a telephone conversation between his ex-wife and their child; the trial court excluded the recording under Idaho's Communications Security Act.
The ruling: The Supreme Court affirmed exclusion, holding the father did not establish vicarious consent on behalf of the child because he lacked an objectively reasonable good-faith belief the recording was necessary to protect the child.
What happened: Law enforcement used pen registers and other surveillance during a drug investigation; the defendant challenged whether the intercepts complied with Idaho's Communications Security Act.
The ruling: The Court of Appeals applied §§ 18-6701–18-6705 and held that evidence obtained through unauthorized interception must be suppressed under Idaho law.
Personal calls vs. business calls in Idaho
Recording personal calls
You can record your own phone calls in Idaho without telling the other person. Documenting an harassing ex, a landlord, or a scammer by recording calls you are on is standard practice and lawful under § 18-6702(2)(d). You cannot tap someone else's line, hide a recorder in their home, or intercept calls between other people without one party's consent — that is a felony with up to five years and civil damages of at least $1,000. If someone gives you an illegally recorded call, disclosing it can be its own crime under § 18-6702(2)(c).
Recording business calls
Idaho businesses may record customer calls when an employee is a party and consents — no announcement is legally required for purely intra-Idaho calls, though disclosure is still best practice. Outbound call centers must still comply with all-party states when dialing California, Washington, or other strict jurisdictions. Employers should not monitor private employee conversations in break rooms or restrooms; the video voyeurism and privacy statutes carry far heavier penalties than ordinary call recording.
Calls that cross state lines
Idaho has no leading appellate decision on which state's law governs cross-border calls. A recorder in Idaho is protected at home, but calling into an all-party state without everyone's consent can still create criminal and civil exposure in that state. Follow the strictest rule on any interstate line.
The safe way to record in Idaho
Whatever the local rule, one habit covers every situation: say the call is being recorded at the start. Consent is then on the recording itself, and cross-border calls stop being a legal puzzle. Callmark can play "This call may be recorded" automatically on your calls, so the disclosure never depends on your memory.

Common questions
Yes. As a participant in the call, your consent satisfies Idaho’s one-party rule. Disclosure is still wise whenever the other party might be in an all-party consent state.
Courts have applied different states' laws to interstate calls, and you often can't verify where a mobile number is. The practical rule: assume the strictest state applies and disclose the recording.
In most states, continuing a call after a clear "this call may be recorded" announcement is treated as implied consent — the same mechanism customer-service lines rely on.
Yes. Idaho Code § 18-6702(2)(d) allows a party to record without notifying the other participants. Your own consent is sufficient.
Yes, if you are not a party and lack any participant's consent. Illegal interception is a felony carrying up to five years and $5,000, plus civil liability of at least $1,000.
Generally yes, if the speakers have no reasonable expectation of privacy. The interception act only protects oral communications made under circumstances justifying a privacy expectation.
Yes, when the employer or a consenting employee is a party to the call. Secretly intercepting employee calls that no consenting participant is on remains illegal.
A one-party participant recording is generally admissible if properly authenticated. Recordings made without any party's consent are inadmissible and expose the recorder to felony prosecution.
