Telephone harassment in Illinois is a criminal offense under 720 ILCS 5/26.5, prosecuted as a Class B misdemeanor for a first offense and escalating to a Class A misdemeanor or a Class 4 felony when specific aggravating factors are present. A first conviction carries up to six months in jail and a fine of up to $1,500; a felony conviction carries one to three years in prison. The statute reaches obscene, threatening, or repeated calls placed with intent to harass, and a parallel provision covers texts, emails, and social media messages.
What Illinois Law Calls Telephone Harassment
Under 720 ILCS 5/26.5-2, a phone call becomes criminal harassment when the caller uses it for one of these purposes:
- Making any comment, request, or suggestion that is obscene or indecent with intent to offend.
- Placing a call with intent to abuse, threaten, or harass the person on the other end, whether or not a conversation actually happens.
- Causing someone’s phone to ring repeatedly with intent to harass.
- Making repeated calls in which conversation does occur, solely to harass.
- Calling, or getting someone else to call, a child under 13 for the purpose of harassing that child, when the caller is at least 16.
- Knowingly letting a phone under your control be used for any of the above.
Intent runs through every category. An annoying or unwelcome call is not, by itself, a crime. The caller must have acted with the purpose to offend, threaten, abuse, or harass. Prosecutors piece intent together from what was said, when it was said, how often the calls came, and the history between the parties. A single 3 a.m. call with threatening language reads very differently from a misdial.
Text, Email, and Social Media Messages
Illinois treats electronic messages under a parallel statute, 720 ILCS 5/26.5-1, that mirrors the telephone provisions and covers texts, emails, direct messages, and any transfer of data over a wire, radio, or electromagnetic system. The prohibited conduct is largely the same, with a few additions tailored to digital technology:
- Interrupting someone’s phone or electronic communication service with intent to harass.
- Sending files or messages designed to prevent the recipient from using their phone or device.
- Threatening injury by electronic message to the recipient, their property, or a family or household member.
The same protection for children under 13 and the same rule about knowingly letting your device be used for harassment apply here too.
Penalties for a First and Second Offense
A first offense of telephone harassment or electronic communications harassment is a Class B misdemeanor: up to six months in jail and a fine of up to $1,500.1Illinois General Assembly. 730 ILCS 5/5-4.5-60 – Class B Misdemeanor Courts can also impose probation, community service, or counseling instead of jail, and first-time offenders with no record often receive those alternatives.
A second or subsequent conviction jumps to a Class A misdemeanor, which carries up to 364 days in jail and a fine of up to $2,500.2Illinois General Assembly. 730 ILCS 5/5-4.5-55 – Class A Misdemeanor Repeat offenders also face mandatory minimums: at least 14 days in jail or, in counties with a public service program, 240 hours of community service.3Illinois General Assembly. HB5320 96th General Assembly – 720 ILCS 135/2 Sentence Those minimums leave little room for leniency once there’s a prior harassment conviction on the record.
When the Charge Becomes a Felony
Certain aggravating circumstances elevate telephone or electronic harassment to a Class 4 felony, punishable by one to three years in prison.4Illinois General Assembly. 730 ILCS 5/5-4.5-45 – Class 4 Felony The felony triggers are specific:
- Three or more prior violations of telephone harassment, electronic communications harassment, or any similar offense in any state within the last 10 years.
- Any prior harassment conviction involving the same victim, or a member of the victim’s family or household, including out-of-state convictions.
- Committing the offense while on bail, probation, mandatory supervised release, or under an order of protection prohibiting contact with the victim.
- Threatening to kill the victim or any member of the victim’s family or household during the offense.
- A forcible felony conviction within the last 10 years, such as robbery, aggravated battery, or sexual assault.
- An adult offender (18 or older) targeting a victim under 18.
The second trigger catches people off guard. A single prior harassment conviction involving the same victim, even a Class B misdemeanor, makes the next incident a felony. That applies regardless of how much time has passed, and out-of-state convictions count.3Illinois General Assembly. HB5320 96th General Assembly – 720 ILCS 135/2 Sentence
Related Charges Prosecutors Often Add
Harassing calls rarely arrive as a single charge. When the conduct fits a broader pattern, prosecutors reach for stalking or cyberstalking, which carry heavier penalties on a first offense.
Stalking under 720 ILCS 5/12-7.3 is a Class 4 felony (one to three years), and a second conviction is a Class 3 felony (two to five years).5Illinois General Assembly. 720 ILCS 5/12-7.3 – Stalking The statute explicitly includes electronic communications, so a course of harassing calls or texts that would place a reasonable person in fear can support the charge. Cyberstalking under 720 ILCS 5/12-7.5 tracks the same structure: Class 4 on a first conviction, Class 3 on a second.6Illinois General Assembly. 720 ILCS 5/12-7.5 – Cyberstalking
Aggravated stalking under 720 ILCS 5/12-7.4 applies when the stalking conduct causes bodily harm, involves confining the victim, or violates an existing protective order. It is a Class 3 felony on a first conviction and a Class 2 felony (three to seven years) on a second.7Illinois General Assembly. 720 ILCS 5/12-7.4 – Aggravated Stalking Threatening calls placed while violating a restraining order exposes the caller to far more than a harassment charge.
Federal law comes in when calls or messages cross state lines. Under 18 U.S.C. ยง 2261A, it is a federal offense to use an interactive computer service or any facility of interstate commerce to engage in conduct that places another person in reasonable fear of death or serious bodily injury, or that causes or would reasonably be expected to cause substantial emotional distress.8Office of the Law Revision Counsel. 18 U.S. Code 2261A – Stalking The government must show the defendant acted with intent to kill, injure, harass, or intimidate, and that the conduct produced one of those results. Federal penalties can go well beyond what Illinois carries.
Defending Against a Harassment Charge
Because intent is central, the strongest defense is usually showing the accused didn’t act with the purpose to threaten, abuse, or harass. Calls made for a legitimate reason, such as following up on a debt, resolving a business dispute, or coordinating shared parenting, can negate the intent element even when the recipient found them unwelcome. Lawful debt collection calls that comply with federal and state regulations sit outside the statute, as do political and advocacy calls that stay within telecommunications law.
Challenging the evidence is another common route. Phone records may be incomplete or ambiguous about who actually placed a call. Voicemails and text messages can lack the context that gives them their meaning. Prosecutors carry the burden of proving guilt beyond a reasonable doubt, and raising real questions about the accuracy or interpretation of the evidence can be enough to defeat a case.
The First Amendment and True Threats
The First Amendment protects offensive, unpopular, and disturbing speech, but not “true threats.” In Counterman v. Colorado (2023), the U.S. Supreme Court held that the government must prove the defendant had some subjective understanding that the statements were threatening. Recklessness is enough: the defendant must have consciously disregarded a substantial risk that the communications would be viewed as threatening violence.9Supreme Court of the United States. Counterman v. Colorado, 600 U.S. 66 (2023) The prosecution does not have to prove the defendant specifically intended the recipient to feel threatened.
That standard sets a constitutional floor for Illinois harassment prosecutions. A defendant who genuinely didn’t realize a message could read as a threat has a viable First Amendment defense. Someone who knew their late-night calls were terrifying the recipient and kept calling meets the recklessness threshold without difficulty.
If You’re the One Being Harassed
Victims in Illinois have two tracks: a court order that prohibits further contact, and, separately, a civil lawsuit for money damages.
Orders of Protection
When the harasser is a family member, household member, spouse, or dating partner, the victim can petition for an order of protection under the Illinois Domestic Violence Act (750 ILCS 60). Courts can grant an emergency order without notice to the respondent, providing immediate protection.10Office of the Illinois Attorney General. Orders of Protection A plenary order follows a hearing where both sides present evidence and can last up to two years. Remedies include no-contact provisions, exclusive possession of a shared residence, firearm prohibitions, and mandated counseling.11Illinois General Assembly. 750 ILCS 60/214 – Order of Protection, Remedies
Stalking No Contact Orders
Many people being harassed by phone don’t have a domestic or dating relationship with the harasser. A coworker, a stranger, or a former friend falls outside the Domestic Violence Act. Those victims can petition for a Stalking No Contact Order under 740 ILCS 21, which was written for stalking victims outside the domestic violence framework.12Illinois General Assembly. 740 ILCS 21 – Stalking No Contact Order Act The petition can be filed in any civil court, including online, on a preponderance-of-the-evidence standard. Emergency orders are available when waiting for a hearing would put the victim at risk.
What Happens if the Order Is Violated
Violating a protective order is a separate criminal offense. Courts impose escalating penalties: at least 24 hours in jail for a first violation and 48 hours for a second.13Illinois General Assembly. 725 ILCS 5/112A-23 – Violation of Order of Protection A violation can bring additional harassment or stalking charges, and committing telephone harassment while subject to a protective order automatically elevates the underlying charge to a Class 4 felony.
Civil Lawsuits
Criminal charges are not the only exposure a harasser faces. Victims can file civil lawsuits for damages, and the two tracks run independently. A civil case can succeed even if no criminal charges are filed or if the defendant is acquitted, because the civil burden of proof is lower.
The usual claim is intentional infliction of emotional distress. The victim must prove the conduct was extreme and outrageous, that the defendant acted intentionally or recklessly, and that the conduct caused severe emotional distress. Persistent threatening calls, especially combined with other intimidating behavior, regularly clear the outrageousness threshold in Illinois courts. Damages can cover therapy costs, lost wages tied to the psychological impact, and the emotional harm itself. Defamation claims may also be available when the harasser made false statements that damaged the victim’s reputation.
What a Conviction Follows You With
Jail time and fines are the visible penalties, but a harassment conviction has a longer tail. Even a Class B misdemeanor appears on background checks and can affect employment, particularly in fields that require licensing, security clearances, or positions of trust. Healthcare, education, finance, and law enforcement employers routinely screen for offenses involving threatening or abusive behavior.
A felony conviction is heavier. Beyond the prison sentence, it can bring loss of voting rights during incarceration, disqualification from certain professional licenses, and a permanent felony record that affects housing and employment for years. Illinois offers paths to expungement and sealing in some circumstances, but the process is slow and does not reach every offense category. Anyone facing a harassment charge, even at the misdemeanor level, has reason to treat it as more than a minor case.
