Harassing calls are different from ordinary spam. Repeated abuse, threats, intimidation, or calls meant to disturb you should be blocked, documented, and reported when they continue.
Does this affect you?
Use this for iPhone, Android, or landline harassment in the United States, including threatening voicemails, repeated calls, or contact from someone who refuses to stop.
Block the caller
This reduces immediate disruption.
- On iPhone, open Phone > Recents, tap the information icon next to the number, and choose Block this Caller.
- On Android, open Phone > Recents, tap and hold the number, and choose Block number or Block/report spam.
- If calls come from many numbers, enable Silence Unknown Callers on iPhone or your carrier’s spam-blocking service.
- If harassment also happens by text, block the contact in Messages.
- If calls are threatening or persistent, keep documenting even after blocking.
Document and report
Evidence matters if police, carriers, or courts need to act.
- Keep a log with date, time, number, and what was said.
- Save voicemails and screenshots. Do not delete evidence.
- Contact your phone carrier and ask about reporting harassment or unwanted calls.
- File a complaint with the FCC at consumercomplaints.fcc.gov if robocalls, spoofing, or telemarketing violations are involved.
- Contact local police if calls include threats of violence, stalking behavior, or harassment by someone you know. Bring the call log and saved voicemails.
- If the caller is violating a restraining or protective order, tell your attorney or the court.
More control
Reports build a record
Carrier and FCC reports may not stop calls immediately, but repeated reports help establish a pattern.
Changing numbers is a last resort
Most carriers can change your number, sometimes free for harassment cases, but it is disruptive. Try blocking, reporting, and screening first when safe.
Mention spoofing patterns
If numbers rotate but follow the same pattern, such as similar area codes or last digits, include that detail in reports.
Treat safety concerns as urgent
If a call makes you feel physically unsafe, contact local police or emergency services instead of waiting on a carrier response.
