If someone keeps calling you, it can be harassment, but repetition alone is not what makes it illegal. Under federal law, phone calls cross into criminal harassment when the caller acts with the intent to threaten, abuse, or annoy you, or causes your phone to ring repeatedly for no purpose other than to distress you. The same conduct can also trigger civil lawsuits, protection orders, and automatic penalties against businesses and debt collectors who ignore the rules.
When Repeated Calls Become Harassment
A single unwanted call is almost never illegal. What matters is the pattern plus the caller’s intent. Federal law makes it a crime to make repeated phone calls solely to harass a specific person, or to cause someone’s phone to ring continuously with the intent to harass.1Office of the Law Revision Counsel. 47 USC 223 – Obscene or Harassing Telephone Calls in the District of Columbia or in Interstate or Foreign Communications The statute also reaches calls placed anonymously when the purpose is to abuse, threaten, or harass.
Prosecutors and courts look at the full picture: how many calls, how close together, the time of day, what was said or not said, and whether the caller had any legitimate reason to reach you. A dozen calls in one evening from an ex-partner who has nothing new to say looks very different from a dozen calls over several weeks from a contractor trying to schedule work. Intent is what separates annoying behavior from criminal conduct.
Silent Calls and Hang-Ups Still Count
You do not need an actual conversation for calls to qualify as harassment. The federal statute specifically covers calls made “whether or not conversation or communication ensues” when the caller hides their identity and intends to harass.1Office of the Law Revision Counsel. 47 USC 223 – Obscene or Harassing Telephone Calls in the District of Columbia or in Interstate or Foreign Communications Calling and hanging up, letting the phone ring without answering, and staying silent on the line all fall within the statute when the intent is to harass. The practical challenge is proving who placed the calls, which is where documentation matters.
What the Caller Can Face
Federal telephone harassment carries real consequences. A conviction under 47 U.S.C. § 223 for making harassing interstate calls can bring up to two years in federal prison, a fine, or both.1Office of the Law Revision Counsel. 47 USC 223 – Obscene or Harassing Telephone Calls in the District of Columbia or in Interstate or Foreign Communications That reach covers repeated calls made solely to harass, anonymous calls intended to threaten or abuse, and calls that cause a phone to ring continuously with harassing intent.
When the behavior escalates into a pattern that causes fear of serious harm or substantial emotional distress, it can also qualify as federal stalking under 18 U.S.C. § 2261A. That statute covers anyone who uses electronic communications or phone services to engage in a course of conduct that places another person in reasonable fear of death or serious injury, or that causes or would be expected to cause substantial emotional distress.2Office of the Law Revision Counsel. 18 USC 2261A – Stalking Federal stalking penalties are significantly harsher than those for basic telephone harassment and scale with the severity of harm. Every state also has its own criminal harassment and stalking laws, many with additional penalties.
Civil Liability
Beyond criminal prosecution, a person who subjects you to extreme and outrageous phone harassment may face a civil lawsuit for intentional infliction of emotional distress. You would need to show the caller’s behavior went beyond the bounds of decency and caused you severe emotional harm. The bar is high, but sustained campaigns of threatening or terrifying calls have cleared it, and winning can produce monetary damages for your distress and related losses.
Different Rules for Businesses and Debt Collectors
When the unwanted calls come from a company rather than an individual, a different and often more powerful set of laws applies, because violations trigger automatic per-call penalties.
Telemarketers and Robocalls
The Telephone Consumer Protection Act restricts how and when businesses can call you. Sales callers cannot call before 8 a.m. or after 9 p.m. in your time zone, and they must get your written consent before placing automated robocalls or sending prerecorded messages to your cell phone.3Federal Trade Commission. Complying with the Telemarketing Sales Rule If a company violates these rules, you can sue in state court and recover $500 for each illegal call, or up to $1,500 per call if the violation was knowing or willful.4Federal Communications Commission. Telephone Consumer Protection Act 47 USC 227 Those numbers add up quickly against a company that has been calling repeatedly.
Debt Collectors
Debt collectors operate under additional restrictions from the Fair Debt Collection Practices Act. Collectors cannot call at unusual or inconvenient times, and the law presumes that calls before 8 a.m. or after 9 p.m. are off-limits. If a collector knows your employer disapproves of personal calls at work, they cannot contact you there either.5Consumer Financial Protection Bureau. When and How Often Can a Debt Collector Call Me on the Phone
The CFPB’s Debt Collection Rule sets a concrete frequency limit. A collector is presumed to be harassing you if they call more than seven times within a seven-day period about a particular debt, or if they call within seven days after already having a phone conversation with you about that same debt.5Consumer Financial Protection Bureau. When and How Often Can a Debt Collector Call Me on the Phone The word “presumed” is important. It means the collector bears the burden of proving the calls were not harassing, rather than you having to prove they were.
Your most powerful tool against a debt collector is a written cease-communication request. Once you notify a collector in writing that you want them to stop contacting you, the FDCPA requires them to stop. The only exceptions let the collector confirm they are ending collection, or tell you that they or the creditor intend to pursue a specific legal remedy like a lawsuit.6Federal Trade Commission. Fair Debt Collection Practices Act Text Send the letter by certified mail so you have proof of delivery. Stopping the calls does not erase the underlying debt.
Spoofed Numbers
Harassing calls often come from numbers that look local or legitimate but are actually faked. Federal law makes it illegal to transmit misleading or inaccurate caller ID information with the intent to defraud, cause harm, or wrongfully obtain anything of value. Violations of the Truth in Caller ID Act can bring penalties of up to $10,000 per violation, capped at $1,000,000 for a single act of continuing violations.7Federal Register. Implementation of the Truth in Caller ID Act of 2009 The FCC has also required phone carriers to authenticate caller ID and offer call-blocking tools, which the agency has pushed them to provide at no additional cost.8Federal Communications Commission. Combating Spoofed Robocalls with Caller ID Authentication If your carrier is not screening suspected spoofed calls, ask what blocking services they offer.
Document Every Call
Good documentation is what separates a complaint from a case. If you ever need a protection order, a police report, or a lawsuit, the strength of your evidence drives the outcome. Start a log and update it after every unwanted call. For each one, record:
- The date and exact time, including the time zone if you travel.
- The caller’s number as it appeared on your screen, even if you suspect it was spoofed.
- The duration of the call.
- What happened: whether the caller spoke, stayed silent, left a voicemail, or hung up.
- What was said, written down as close to verbatim as you can manage immediately afterward.
Take screenshots of your call history regularly. Save every voicemail and text message, and back them up somewhere the caller cannot access. If calls come through messaging apps, screenshot those logs too.
Recording Calls
A recording captures evidence that a written log cannot. Federal law allows you to record a phone call as long as you are a party to the conversation and you consent to the recording.9Office of the Law Revision Counsel. 18 USC 2511 – Interception and Disclosure of Wire, Oral, or Electronic Communications But roughly a dozen states require every party on the call to consent before recording is legal. If you live in one of those states, or the caller is in one, recording without full consent could expose you to liability. Check your state’s rule before you hit record.
How to Make the Calls Stop
The most effective response combines immediate self-help with formal reporting, and escalates as needed.
Tell the Caller to Stop, Once
Clearly tell the caller not to contact you again. Do it once, note the exact date and time you said it, and do not engage further. This matters legally because it eliminates any argument that the caller thought the calls were welcome. For debt collectors, put the request in writing and send it by certified mail to trigger the FDCPA’s mandatory cease-communication requirement.6Federal Trade Commission. Fair Debt Collection Practices Act Text
Block and Filter
Block the caller on your phone. If the calls come from a rotating set of numbers, ask your carrier about their blocking and filtering services. Most major carriers offer them, often free. Your phone’s built-in settings can also silence calls from unknown numbers, though that approach may filter out calls you actually want.
Register on the Do Not Call List
If the problem is unwanted sales calls, register your number with the National Do Not Call Registry at DoNotCall.gov or by calling 1-888-382-1222 from the phone you want to register. Registration is free, never expires, and the FTC removes a number only if it gets disconnected and reassigned.10Federal Trade Commission. National Do Not Call Registry FAQs The registry stops sales calls from legitimate companies that follow the law. It does not stop political calls, charitable solicitations, surveys, debt collection calls, or illegal robocallers who ignore the rules entirely.
Get a Protection Order
When a known person will not stop calling despite being told to, a civil protection order (sometimes called a restraining order) can legally prohibit them from contacting you by phone or any other method. Violating that order is a separate criminal offense, which gives law enforcement a clear basis to arrest the caller if they continue. For a persistent individual harasser, this is often the single most effective tool, because it turns every future call into an independent crime.
Report to Law Enforcement and Agencies
If the calls are threatening or you fear for your safety, go to your local police with your call log, saved voicemails, screenshots, and any recordings. For harassing telemarketing or robocalls, file a complaint with the FCC through its consumer complaint center.11FCC Complaints. Unwanted Calls/Texts – Phone For debt collector violations, report the collector to the Consumer Financial Protection Bureau, the Federal Trade Commission, and your state attorney general.12Federal Trade Commission. Debt Collection FAQs A single complaint may not trigger immediate action, but agencies use the data to build enforcement cases against repeat offenders.
File a Private Lawsuit
For TCPA violations by businesses, you do not have to wait for the government to act. You can sue in state court for $500 per illegal call, or up to $1,500 per call if the violations were willful.4Federal Communications Commission. Telephone Consumer Protection Act 47 USC 227 Attorneys who handle these cases often work on contingency because the per-call damages add up quickly against a company that has been calling repeatedly. For an individual harasser, a civil suit for intentional infliction of emotional distress is possible when the conduct has been severe enough to cause serious psychological harm.
