The fastest way to block a telemarketer call

When a telemarketer calls, let it ring to voicemail, then open the Phone app, find the number in your recent calls list, tap the info icon (the small circle with an "i"), scroll down, and tap Block this Caller. That number will never ring your phone again — the call goes straight to voicemail, and you won't see a notification.

If you answer by accident, you can block them mid-call: tap the red phone icon to hang up, then when ready tap Recents at the bottom of the Phone app, find that call at the top of the list, tap the info icon, and select Block this Caller.

Blocked numbers can still leave voicemails, but you won't hear them ring. If you want to hear what they left, you can listen in the Voicemail tab — but most telemarketers hang up without leaving a message.

Key Takeaways

  • Block individual numbers through the Phone app's Recents list by tapping the info icon and selecting Block this Caller.
  • Unknown callers can be silenced automatically by turning on Silence Unknown Callers in Settings > Phone, which sends calls from numbers not in your contacts straight to voicemail.
  • Do Not Disturb can be set to allow calls only from your contacts, blocking all others including telemarketers, though this affects all incoming calls.
  • Reporting numbers to the FTC through their website creates a record that helps law enforcement track illegal calling patterns.

Silence all unknown numbers at once

If you get telemarketer calls constantly, the fastest solution is to silence every number that isn't in your contacts. Open Settings, tap Phone, scroll down, and turn on Silence Unknown Callers. From that moment on, any call from a number you haven't saved goes straight to voicemail with no ring or notification.

This stops most telemarketer calls without you having to block them one at a time. The downside: if someone you know calls from an unfamiliar number — a doctor's office, a friend borrowing a phone, a business you called back — you won't see it come in. You'll only find it in your Voicemail tab later.

If that's too aggressive, you can turn it off anytime by going back to Settings > Phone and toggling it off. Many people turn it on during work hours and off at night, or keep it on permanently and check voicemail once a day.

Use Do Not Disturb to block calls from non-contacts

Do Not Disturb is a broader tool that silences calls, texts, and notifications from everyone except people in your contacts. Open Settings, tap Focus, then tap Do Not Disturb. Tap Add at the bottom, then choose Calls and set it to Allow Calls From: Contacts.

Once you turn on Do Not Disturb, telemarketer calls won't ring or light up your screen. You can set it to turn on automatically at certain times — for example, every evening after 6 p.m. — by tapping Add Schedule and choosing your hours.

The difference between Do Not Disturb and Silence Unknown Callers is control: Do Not Disturb lets you set schedules and exceptions, while Silence Unknown Callers is always on or always off. Do Not Disturb also silences texts and notifications, which Silence Unknown Callers does not.

Report numbers to stop them from calling others

Blocking a number protects you, but reporting it helps stop the caller from reaching anyone else. When you get a telemarketer call, open the Phone app, find the number in Recents, tap the info icon, scroll all the way down, and tap Report as Junk. This tells Apple the number is spam.

For illegal robocalls or scams, you can also report to the Federal Trade Commission at reportfraud.ftc.gov. The FTC doesn't contact you back, but it tracks patterns across thousands of reports and shares them with law enforcement. If you report the same number multiple times from different people, it becomes evidence of an illegal calling campaign.

Reporting takes 30 seconds and costs nothing. It won't stop that specific caller from trying again, but it creates a record that can lead to enforcement action against the company behind the calls.

What to do if a telemarketer keeps calling from different numbers

Some telemarketer operations use software that generates new numbers for each call, making it impossible to block them one at a time. If you're getting calls from dozens of different numbers claiming to be from the same company, Silence Unknown Callers is your only real defense — blocking individually won't work.

Turn on Silence Unknown Callers and check your voicemail once a day. If any of those calls are from someone you actually need to hear from, they'll leave a message and you can call them back. Legitimate callers almost always leave voicemail; telemarketers almost never do.

If the calls are from a scam or illegal operation, report a few of the numbers to the FTC. Include the company name they claim to be from, even if you don't believe it — that information helps investigators identify the actual operation behind the calls.

Blocking vs. reporting: what's the difference

Blocking stops a specific number from reaching you. It's when ready, it's permanent until you unblock, and it only affects your phone. Reporting tells Apple or the FTC that a number is spam or a scam, which helps them track patterns and take action against the caller.

You should do both when you can. Block the number so it stops ringing your phone, then report it so the company gets flagged in Apple's spam database or the FTC's fraud records. Reporting takes 10 extra seconds and doesn't change anything on your phone — it just adds your report to thousands of others that help identify illegal operations.

Frequently Asked Questions

Can a blocked caller still reach me if they call from a different number?

Yes. Blocking stops one specific phone number, not a person or company. If a telemarketer calls from 555-0100 and you block it, they can call from 555-0101 tomorrow and you'll see it ring. This is why Silence Unknown Callers is more effective against persistent telemarketers — it blocks all numbers you haven't saved, not just one.

Will the blocked caller know they're blocked?

No. The call goes to your voicemail, and from their end it looks like a normal voicemail pickup. They won't hear a message saying they're blocked. Some may leave a voicemail, but you won't be notified — you'll only see it if you check the Voicemail tab.

What happens if I block someone by accident?

Open the Phone app, tap Recents, find the number, tap the info icon, scroll down, and tap Unblock this Caller. They can reach you normally again when ready. You can also manage all blocked numbers in Settings > Phone > Blocked Contacts.

Does blocking a number stop text messages from that number?

Yes. Blocking a number blocks calls, texts, and FaceTime from that number. Messages from blocked numbers go to a separate folder in the Messages app that you can check if needed, but you won't get a notification.

Is there a way to block all calls except my contacts?

Yes, using Do Not Disturb set to allow calls only from Contacts. This is more aggressive than Silence Unknown Callers because it also silences texts and notifications, but it's the most complete way to block all non-contact calls. You can turn it on and off as needed or set it to turn on automatically at certain times.
