Is it legal to record phone calls in California?
Only with everyone’s consent. California is an all-party consent state: every participant in a phone call must consent to being recorded. The standard mechanism is a clear announcement — a party who stays on the line after hearing “this call may be recorded” is generally treated as having consented.
What California law says
California is one of roughly a dozen US states that require all parties’ consent to record a phone call. Recording without consent can carry criminal penalties and civil liability, so the practice to adopt is simple: announce the recording at the start of every call, or use a tool that announces it for you. California’s Invasion of Privacy Act (CIPA) is the strictest and most litigated recording statute in the country, covering “confidential communications.”
California requires the consent of every party before recording a phone call. Section 632 prohibits recording any "confidential communication" without all parties' consent, and section 632.7 separately prohibits recording any call involving a cellular or cordless phone — no confidentiality showing required. The California Supreme Court has confirmed that section 632.7 binds the people on the call, not just outside eavesdroppers, making California one of the strictest recording states in the country.
"Every person who, intentionally and without the consent of all parties to a confidential communication, by means of any electronic amplifying or recording device, eavesdrops upon or records the confidential communication, whether the communication is carried on among the parties in the presence of one another or by means of a telegraph, telephone, or other device, except a radio, shall be punished by a fine not exceeding two thousand five hundred dollars ($2,500), or imprisonment in the county jail not exceeding one year, or in the state prison, or by both that fine and imprisonment." — Cal. Penal Code § 632(a)
Federal law under 18 U.S.C. § 2511(2)(d) permits recording a call when one party consents — a lower bar than California's all-party rule. But the federal Wiretap Act does not preempt stricter state law: a recording lawful under federal one-party principles can still violate CIPA and expose the recorder to California criminal penalties, $5,000-per-call civil damages under § 637.2, and suppression of the recording as evidence. Businesses operating nationally cannot rely on federal one-party consent as a shield when calling California residents.
All parties must consent, and consent can be express or implied from clear notice: if a caller hears "this call may be recorded" and stays on the line, continuing the conversation is treated as consent — this announcement mechanism is how virtually every California business complies. Under section 632, only "confidential communications" are protected, and in Flanagan v. Flanagan the Supreme Court set a low bar: a communication is confidential whenever a party has an objectively reasonable expectation the conversation is not being overheard or recorded, regardless of whether its content is secret. Section 632.7 sweeps even wider for any call in which one end is a cell phone or cordless phone — which today is nearly every call — prohibiting nonconsensual recording without any confidentiality requirement, and Smith v. LoanMe held it applies to parties to the call, not just third-party interceptors. Communications made in public gatherings, in open court or public proceedings, or in circumstances where the parties should reasonably expect to be overheard fall outside section 632's protection. Recording announcements at the very start of the call matter: notice given after the recording has begun protects only what follows.
| Consent rule for phone calls | All-party consent |
| Recording calls you're part of | Only with every participant’s consent — announce the recording. |
| Calls with people in other states | The stricter state's rule may apply — when in doubt, disclose. |
What breaking the law costs in California
Violating section 632 or 632.7 is punishable by a fine of up to $2,500 per violation and/or up to one year in county jail (it can be charged as a misdemeanor or, in some circumstances, with state-prison exposure). Repeat offenders face fines of up to $10,000 per violation.
Yes — section 637.2 gives anyone injured by a violation a private right of action for the greater of $5,000 per violation or three times actual damages, and expressly says the plaintiff need not have suffered any actual damage. Injunctive relief is available, and the per-violation math is why California call-recording class actions are so common. Illegally recorded conversations are also inadmissible as evidence under section 632(d), except in prosecutions for the violation itself or for crimes covered by section 633.5.
Exceptions worth knowing
- Announced recording: notice at the outset plus the caller's decision to continue constitutes consent
- Crime-evidence exception (§ 633.5): one party may secretly record to gather evidence of extortion, kidnapping, bribery, a felony involving violence (including human trafficking), harassing calls under § 653m, or domestic violence — and such recordings are admissible in prosecutions for those crimes
- Law enforcement acting within the scope of existing legal authority (§ 633)
- Communications with no reasonable expectation of privacy — public gatherings, public proceedings, or circumstances where being overheard is reasonably expected (§ 632(c)); note § 632.7 can still cover cell and cordless calls
How California 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 California law.
What happened: Brokers in Salomon Smith Barney's Atlanta office routinely recorded phone calls with their California clients without telling them — legal under Georgia's one-party rule, illegal under California's.
The ruling: The court held California law applies to calls made into California, allowing the clients' claims to proceed for injunctive relief, though it declined to impose damages for past conduct given the firm's reliance on Georgia law.
What happened: A lender recorded an 18-second call it placed to a borrower's husband, who answered on a cordless phone; the only notice was a "beep" three seconds in, and he sued under section 632.7. The Court of Appeal had held section 632.7 restricts only third-party eavesdroppers, not participants.
The ruling: The Supreme Court reversed, holding section 632.7 prohibits parties as well as nonparties from recording cellular or cordless phone calls without all parties' consent.
What happened: In a family feud over a wealthy father's estate, his wife used a voice-activated recorder installed in the home to secretly tape phone calls between the father and his son; a jury found most of the calls confidential and awarded $5,000 per call plus punitive damages.
The ruling: The Supreme Court held a conversation is "confidential" under section 632 whenever a party has an objectively reasonable expectation that it is not being overheard or recorded — rejecting the stricter view that the content itself must be intended as secret.
What happened: A lender's supervisors secretly monitored calls between its own employees and borrowers; the trial court held a company cannot "eavesdrop" on its own employees' calls because the two employees counted as one person.
The ruling: The Court of Appeal reversed, holding section 632 applies even when the unannounced listener works for the same company as the known participant, though whether callers reasonably expected privacy is a question of fact.
What happened: A class of consumers sued a debt collector for recording collection calls to Californians without all-party consent, seeking statutory damages under CIPA.
The ruling: The Court of Appeal held that each nonconsensual recording of a call to a California resident is a separate violation subject to statutory damages, fueling the wave of CIPA class actions against out-of-state callers.
What happened: An attorney secretly recorded telephone conversations with opposing counsel and a witness during a fee dispute, then sought to use the tapes in disciplinary proceedings.
The ruling: The court held the recordings violated section 632 and were inadmissible; the attorney faced professional discipline for the illegal interception.
Personal calls vs. business calls in California
Recording personal calls
Secretly recording your own calls is generally illegal in California, even for sympathetic reasons: Flanagan shows a family member paying statutory damages per recorded call, and Smith v. LoanMe confirms participants are covered. If you want a usable recording of a call with an ex, a landlord, or a business, say you are recording at the start and let the other person's decision to continue serve as consent. The major carve-out is section 633.5: if you are gathering evidence of extortion, kidnapping, bribery, a violent felony, harassing phone calls, or domestic violence committed by the other party, you may record secretly, and the recording is admissible in a prosecution for that crime — a narrow but important protection for people documenting threats or abuse. Outside that exception, an illegal recording is inadmissible in court and can itself cost you $5,000 per call in civil damages plus criminal exposure.
Recording business calls
Every business call touching California should begin with a recording disclosure — the familiar "this call may be recorded" line — because continuing after notice constitutes consent, and skipping it invites class actions seeking $5,000 per call under section 637.2. That applies to inbound and outbound calls, and Kight v. CashCall extends it to silent supervisor monitoring, not just recording. Out-of-state companies get no pass: Kearney holds California law governs calls with Californians even when the company's home state allows one-party recording. Employers may record customer-facing calls after disclosure, but secretly monitoring employees' calls — including by their own managers — violates CIPA where the participants reasonably expected privacy.
Calls that cross state lines
California is the leading state on cross-border recording law. In Kearney v. Salomon Smith Barney, the California Supreme Court held that when a call crosses state lines into California, California's all-party-consent rule applies — an out-of-state business recording under its home state's one-party rule can be enjoined and, for conduct after Kearney, held liable. The practical consequence nationwide: anyone who might be calling a California number should obtain all-party consent.
The safe way to record in California
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
Only if everyone on the call consents. An announcement at the start of the call, followed by the other party staying on the line, is the standard way consent is established in California.
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.
In defined situations, yes. Penal Code § 633.5 lets one party secretly record a communication to obtain evidence of extortion, kidnapping, bribery, a felony involving violence, harassing calls under § 653m, or domestic violence, and the recording is admissible in a prosecution for those crimes. For anything short of those categories — ordinary arguments, custody disputes, contract fights — secret recording remains illegal.
It is unsettled. California regulators have historically treated periodic beep tones as one form of notice, and in Smith v. LoanMe the trial court thought a beep sufficed — but the Supreme Court decided the case on other grounds and never ruled on it. A clear verbal announcement at the start of the call is the only approach courts have consistently treated as adequate notice.
California law can still reach you. Under Kearney v. Salomon Smith Barney, California courts apply the all-party-consent rule to calls made to people in California, whatever the law of the state you are calling from. Businesses and individuals who record interstate calls should follow the strictest state on the line.
Generally no. Section 632(d) makes evidence obtained in violation of the statute inadmissible in judicial and administrative proceedings, except in a prosecution of the illegal recording itself or where the § 633.5 crime-evidence exception applies. The recording can still be used against the person who made it.
Only with notice. Employers may record or monitor customer calls when all participants have been informed — the standard disclosure covers both the customer and the employee. Kight v. CashCall holds that secret monitoring by a supervisor can violate § 632 even though the supervisor and employee work for the same company.
