California Telemarketing and Text Laws: A Map for Businesses
California layers its own telemarketing rules on top of the federal Telephone Consumer Protection Act: a near-ban on text ads, a state Do Not Call law with brand-wide stop requests, live-voice and AI-disclosure rules for recorded-message dialers, and a consumer protection rule for prerecorded calls. Most of them aren’t enforced through per-call damages suits. For businesses calling or texting Californians, the TCPA still drives litigation exposure, and the state rules shape what a defense looks like.
California’s Do Not Call law
California adopted the national Do Not Call Registry as its own list. Its statute opens by declaring “a compelling state interest to protect the privacy of residential or wireless telephone subscribers who wish to avoid unsolicited and unwanted telephone solicitations,” under Business and Professions Code § 17590. Cell phones are covered by name, so the argument some federal courts have accepted, that federal Do Not Call rules reach only landlines, doesn’t carry over to the state statute.
Two features are stricter than federal law. Written permission to call a registered number can’t come from fine print: an express agreement “does not include any consent or permission included in any contract of adhesion,” under § 17592. And a stop request follows the brand. The statute makes “that instruction shall be binding on the entity with which the subscriber has the established business relationship, with any entity that has the shared brand name, and all other entities that share that brand name.” Companies running several entities under one brand need one suppression list, not several.
The private remedy is limited. A person who receives a prohibited call “may bring a civil action in small claims court for an injunction or order to prevent further violations,” under § 17593, and can seek a penalty of up to $1,000 only if calls continue within 30 days after the order is served. Public prosecutors can seek larger civil penalties. The statute also gives a defense where a violation was accidental and contrary to the company’s own policies and training.
Text-message advertising
Business and Professions Code § 17538.41 provides that “no person, entity conducting business, candidate, or political committee in this state shall transmit, or cause to be transmitted, a text message advertisement to a mobile telephony services handset.” The main exception covers businesses and campaigns with an existing relationship with the recipient that offer an opt-out.
Enforcement runs through public channels. The Legislature’s summary says “Existing law enforces these prohibitions pursuant to the provisions related to unfair competition and makes a violation of these provisions a misdemeanor,” according to the Legislative Counsel’s Digest for AB 1865. That bill would have added a private claim for “Five hundred dollars ($500) per text message advertisement, actual damages, or statutory damages, whichever amount is greater” and a ban on text ads between 9 p.m. and 9 a.m. even with consent. The Appropriations Committee held it on May 14, 2026, according to the bill history.
I’d treat AB 1865 as a preview, not a dead letter. A private right of action for text ads would turn California into one of the most active states for text litigation overnight, and companies that already confine sends to daytime hours will have far less to unwind if it returns.
Recorded-message dialers
California calls them automatic dialing-announcing devices. Two rules matter most. First, hours: “A person shall not operate an automatic dialing-announcing device in this state to place a call that is received by a telephone in this state during the hours between 9 p.m. and 9 a.m. California time,” under Public Utilities Code § 2872. Second, a live voice first: the device “may be operated only after an unrecorded, natural voice announcement has been made to the person called by the person calling,” under § 2874, and since 2025 that announcement must “Inform the person called if the prerecorded message uses an artificial voice.”
These rules sit under the Public Utilities Commission’s jurisdiction. They don’t apply to dialers that don’t dial randomly or sequentially and are used only to reach existing customers or people who asked for the call.
Prerecorded calls under the CLRA
The Consumers Legal Remedies Act lists as unlawful “Disseminating an unsolicited prerecorded message by telephone without an unrecorded, natural voice first informing the person answering the telephone of the name of the caller or the organization being represented,” under Civil Code § 1770(a)(22). It exempts messages to people with an established relationship, calls to collect an existing obligation, and calls the recipient requested. Plaintiffs sometimes plead it alongside a TCPA recorded-voice claim.
Collection calls and the Rosenthal Act
California’s debt collection statute reaches further than federal law. It defines a debt collector as “any person who, in the ordinary course of business, regularly, on behalf of that person or others, engages in debt collection,” under Civil Code § 1788.2, which covers creditors collecting their own debts. It bars “Causing a telephone to ring repeatedly or continuously to annoy the person called,” under § 1788.11. Collection robocall cases in California often pair a Rosenthal claim with a TCPA claim.

Getting a California calling program in order
- Preserve call and text logs for California numbers, including the consent record behind each one, and put them on hold as soon as a claim or regulator inquiry arrives.
- Merge suppression lists across every entity that shares a brand, since a California stop request reaches all of them.
- Keep the Registry scrub records for California campaigns and the dates of each version used.
- Collect dialer settings, recorded-message scripts, and the live-introduction script, including any AI-voice disclosure.
- Talk to a lawyer before responding to a demand letter, a small claims filing, or a prosecutor’s inquiry.

California compliance questions, answered
Does California’s Do Not Call law allow per-call damages?
No. A consumer can seek a small claims injunction, and a penalty of up to $1,000 only if calls continue after the order is served. Larger civil penalties are available to the Attorney General, district attorneys, and city attorneys. The per-call exposure for most companies still comes from the federal TCPA.
Can a consumer sue us for statutory damages over a California text ad?
Not under the text-ad statute as it stands, which is enforced through unfair competition law and criminal prosecution. AB 1865 would have created a $500-per-text private claim, but it stalled in committee in May 2026. Federal TCPA claims over the same texts remain possible.
Do California’s dialer rules cover live agents?
No. The hours and live-introduction rules apply to automatic dialing-announcing devices, which play recorded messages. A live agent calling a California number is governed by the federal telemarketing rules and California’s Do Not Call statute, not the dialer article. AI voices are treated as recorded messages for the disclosure rule. If those calls are recorded, our post on California call-recording claims covers the consent rules.
Is a single brand-wide suppression list really necessary?
For California numbers, yes. The state statute makes a stop request binding on every entity that shares the brand name. A customer who opts out from one affiliate and hears from another is exactly the scenario the statute was written to stop.
