Quick answer: California Penal Code § 653m makes it a misdemeanor to use a telephone or electronic communication device to harass another person in either of two ways. Under subdivision (a), it is a crime to contact someone with intent to annoy and to use obscene language, or to threaten injury to the person, their property, or a member of their family. Under subdivision (b), it is a crime to make repeated calls or repeated electronic contacts with intent to annoy or harass, whether or not anyone answers. The law covers calls, texts, emails, and social media messages. It does not apply to contacts made in good faith. The maximum penalty is generally six months in county jail and a $1,000 fine. The usual defenses are a legitimate purpose for the contact, lack of intent to annoy or harass, and lack of proof of who sent the messages.
| Subdivision (a) | Subdivision (b) | |
|---|---|---|
| Conduct | A call or electronic contact in which the person uses obscene language, or threatens to injure the recipient, the recipient’s property, or a family member | Repeated calls, repeated electronic contacts, or a combination |
| Intent | Intent to annoy | Intent to annoy or harass |
| Number of contacts | One is enough | More than one |
| Must anyone answer? | The language must be addressed to or about the other person | No. The offense is complete “whether or not conversation ensues.” |
| Exception | Contacts made in good faith | Contacts made in good faith or during the ordinary course and scope of business |
| Classification | Misdemeanor | Misdemeanor |
In this statute, “obscene” is not limited to the constitutional definition of obscenity used for pornography laws. In People v. Hernandez (1991) 231 Cal.App.3d 1376, the Court of Appeal read the term in its ordinary sense: language that is offensive to accepted standards of decency. Crude sexual references and vulgar insults aimed at the listener have been treated as qualifying when coupled with intent to annoy.
Section 653m does not specify its own punishment, so the general misdemeanor statute applies (Penal Code § 19):
A criminal court can also issue a criminal protective order while the case is pending. Although § 653m is a low-level misdemeanor, a conviction appears on background checks and can be cited in later restraining order, custody, and licensing proceedings. Each separate course of contact, and each victim, can be charged as a separate count.
| Statute | What must be proven | Level |
|---|---|---|
| Penal Code § 653m | Intent to annoy or harass, plus obscene or threatening language, or repeated contact | Misdemeanor |
| Penal Code § 646.9 (stalking) | Repeated following or harassment, plus a credible threat intended to cause reasonable fear | Wobbler or felony |
| Penal Code § 422 (criminal threats) | A threat of death or great bodily injury, intended as a threat, causing sustained fear | Wobbler and a strike as a felony |
| Penal Code § 653.2 | Electronically distributing personal information to incite harassment by others | Misdemeanor |
| Penal Code § 647(j)(4) | Distributing intimate images without consent, causing serious emotional distress | Misdemeanor |
| Penal Code § 273.6 | Knowing violation of a protective order | Misdemeanor in most cases |
| Penal Code § 136.1 | Attempting to dissuade a victim or witness from reporting or testifying | Wobbler or felony |
Prosecutors sometimes file § 653m as a lesser alternative to stalking or criminal threats, and it is a common negotiated resolution when the evidence of a credible threat is weak.
Conduct described in § 653m shows up in restraining order law in three ways.
The standards differ. A § 653m conviction requires proof beyond a reasonable doubt. A domestic violence restraining order requires a preponderance of the evidence, and a civil harassment order requires clear and convincing evidence. A person can avoid criminal charges and still face a multi-year restraining order based on the same messages. And statements made in the restraining order case can be used in the criminal case. See burden of proof in restraining order cases and restraining order hearings with a pending criminal case.
The statute excludes contacts made in good faith. Calls and messages about custody exchanges, a child’s medical needs, shared bills, return of property, a real business matter, or a pending legal case have a legitimate purpose. The defense shows the purpose through the content of the messages themselves and the surrounding circumstances.
Intent is usually inferred from volume, timing, and content, and it can be rebutted the same way. Messages sent in distress, in an attempt to reconcile, or in response to the other person’s own messages do not necessarily show an intent to annoy. The full thread, including what the complaining witness wrote, is often the best defense evidence.
For subdivision (a), ordinary profanity used in an argument is different from obscene language directed at a person with intent to annoy, and an ambiguous or conditional statement may not be a threat to inflict injury.
For subdivision (b), a single message, or a handful spread over a long period for different reasons, may not qualify.
The prosecution must prove who sent the messages. A phone number, username, or email address can be shared, borrowed, spoofed, or created by someone else. Carrier records, device data, and account logs can confirm or contradict the accusation. Screenshots offered without the underlying data can be challenged on authentication.
Evidence that the recipient was calling and messaging in return, or invited the contact, undercuts both the intent element and the claim of harassment. This is not a defense once a restraining order prohibits contact.
The statute targets harassing conduct, not ideas. Communications on matters of legitimate concern that are not obscene, not threatening, and not repeated for the purpose of harassment are outside its scope.
Because § 653m is a misdemeanor that is not excluded from court-initiated diversion under Penal Code § 1001.95, a judge may have discretion to divert the case and dismiss it on completion of conditions. Some prosecuting agencies also resolve these cases through an office hearing without filing charges.
| Conduct | Likely analysis |
|---|---|
| Thirty calls between midnight and 3 a.m. after a breakup, most unanswered | Repeated contact from which intent to annoy or harass can be inferred. Subdivision (b). |
| One voicemail with vulgar sexual insults | Obscene language addressed to the person. Subdivision (a), if intent to annoy is shown. |
| One text: “I’ll slash your tires” | A threat to property. Subdivision (a). |
| Daily texts to a co-parent about pickup times and school forms | Good faith contact with a legitimate purpose. Not a violation. |
| A contractor calling repeatedly about an unpaid invoice during business hours | Ordinary course of business. Not a violation, absent threats or obscene language. |
| Messages from a newly created anonymous account | Depends on proof of who controlled the account |
| Two people trading insults by text for an hour | Mutual argument. Intent to annoy by one side alone is hard to prove. |
Examples are illustrative. Charging decisions depend on all of the evidence.
The statute of limitations for a misdemeanor is generally one year, so older messages may fall outside what can be charged even if they are offered as background.
It prohibits two things: contacting another person by telephone or electronic communication device with intent to annoy and using obscene language or threatening injury to the person, their property, or their family; and making repeated calls or electronic contacts to another person with intent to annoy or harass.
It is a misdemeanor. The maximum penalty is generally up to six months in county jail, a fine of up to $1,000, or both. The court may also order counseling as a condition of probation.
The statute does not set a number. Repeated means more than once, and in practice prosecutors look at volume, timing, content, and whether the sender was told to stop.
No. Under the repeated-contact provision, the offense is complete whether or not a conversation takes place.
Yes. The statute covers contact by an electronic communication device, which includes cell phones, computers, and similar devices, so texts, emails, and direct messages can be charged.
Section 653m does not apply to calls or electronic contacts made in good faith, and the repeated-contact provision also excludes contacts made during the ordinary course and scope of business. Contact with a real and legitimate purpose, such as arranging a custody exchange or resolving a bill, is not a crime even if it is unwelcome.
Stalking under Penal Code 646.9 requires a credible threat made with intent to place the person in reasonable fear for their safety, and it can be a felony. Section 653m requires only intent to annoy or harass and is always a misdemeanor.
If a restraining order prohibits contact, each call or message can be charged as a violation of that order under Penal Code 273.6, in addition to or instead of section 653m. A violation of a restraining order usually carries heavier penalties.
The offense may be treated as committed either where the calls or messages were sent or where they were received, so a case can be filed in the recipient’s county.
Yes, depending on the facts. Cases are dismissed when the prosecution cannot prove who sent the messages or the required intent, when the contact had a legitimate purpose, or through diversion or informal resolution, which some courts allow for this offense.
