How to Silence Unknown Callers on WhatsApp

Unexpected WhatsApp calls can be distracting, especially when they come from numbers you do not recognise. WhatsApp includes a privacy setting that prevents calls from unknown people from ringing, while still keeping a record of those calls in case one was legitimate.

This guide explains how to silence unknown callers on WhatsApp for Android and iPhone, what the setting does, what it does not block, and how to handle repeated or suspicious callers safely.

What Silence Unknown Callers does

When Silence unknown callers is enabled, WhatsApp calls from unknown people do not ring on your phone. According to WhatsApp, the calls still appear in the Calls list so you can review them later.

The feature is designed to reduce interruptions from spam, scam attempts and unfamiliar callers. It is a screening tool rather than a block:

• The incoming call is silenced instead of ringing normally.
• The call remains visible in WhatsApp’s Calls tab.
• The caller is not automatically blocked or reported.
• Your saved contacts can still call normally.
• You can turn the setting off at any time.

This balance is useful when you want fewer interruptions without completely losing the record of a potentially important call.

How to silence unknown WhatsApp callers on Android

1. Open WhatsApp.
2. Tap the three-dot menu in the upper-right corner.
3. Select Settings.
4. Tap Privacy.
5. Scroll down and choose Calls.
6. Turn on Silence unknown callers.

The change takes effect immediately. You do not need to restart WhatsApp or your phone.

How to silence unknown WhatsApp callers on iPhone

1. Open WhatsApp on your iPhone.
2. Tap Settings at the bottom of the screen.
3. Select Privacy.
4. Tap Calls.
5. Switch on Silence Unknown Callers.

If you cannot see the option, update WhatsApp from the App Store and check again. The menu wording may vary slightly by app version, but the control should be inside Settings > Privacy > Calls.

Where silenced calls appear

A silenced call is not erased. Open WhatsApp and select the Calls tab to see the number, call type and time. This lets you decide whether to ignore the caller, check the number, save it as a contact or return the call.

Do not call back automatically just because the number appears in the list. If you do not recognise it and were not expecting a call, first consider whether the person left a credible message or can be identified through another trusted channel.

Silencing is different from blocking

Silencing unknown callers controls whether unfamiliar calls ring. It does not prevent the same person from sending messages or attempting more calls. Blocking is the stronger option when a particular account is unwanted.

Use silencing when:

• You receive occasional calls from unfamiliar numbers.
• You want unknown calls recorded without being interrupted.
• You may receive legitimate calls from people who are not yet in your contacts.
• You prefer to review calls at a convenient time.

Use blocking when:

• The same account repeatedly contacts you without permission.
• The caller sends spam, threats or suspicious links.
• You know you do not want any further contact from that account.
• The account appears to be impersonating a person or business.

How to block or report an unknown WhatsApp caller

If an unknown account also sends you a message, open that chat and use the available block or report controls. On Android, WhatsApp’s official instructions include opening the chat, tapping the three-dot menu, choosing More, then selecting Block. You can also choose to report the account to WhatsApp.

Blocking stops that account from contacting you through normal WhatsApp calls and messages. Reporting sends recent information about the interaction to WhatsApp for review. Use the report option for suspected spam, scams, harassment or other policy violations—not simply because you do not recognise a legitimate caller.

Should you answer an unknown WhatsApp call?

There is no need to answer a call you were not expecting. A genuine person can usually introduce themselves in a message, leave a voicemail where supported, or contact you through another channel.

Be cautious if the caller:

• Creates urgency or asks you to act immediately.
• Claims your account, delivery, bank or government record has a problem.
• Requests a verification code, password, PIN or screen-sharing session.
• Asks you to install an app or visit an unfamiliar link.
• Offers a prize, job or investment that you did not apply for.
• Pressures you to move money or buy gift cards.

WhatsApp will not need you to share your six-digit registration code in a call. Never reveal authentication codes or passwords, even if the caller knows personal information about you.

Why unknown WhatsApp calls may still appear

The setting is meant to stop ringing, not remove all evidence of the call. Seeing an entry in the Calls tab therefore does not mean the feature failed. The record remains so that you can identify a legitimate missed call.

If the phone still rings, check the following:

Confirm the switch is still enabled

Open WhatsApp > Settings > Privacy > Calls and confirm Silence unknown callers is on. An app reinstall, account change or restored backup may require you to review settings again.

Check whether the number is saved

A saved contact is not treated as unknown. Search your phone’s Contacts app and WhatsApp address book for the number. Remove it only if you no longer want that person treated as a known contact.

Update WhatsApp

Install the latest version from Google Play or the App Store. Avoid unofficial WhatsApp downloads, because they may lack security updates and can put the account at risk.

Restart the app

Close WhatsApp fully and reopen it. If the setting still behaves unexpectedly, restart the phone before changing unrelated notification controls.

Will this silence ordinary phone calls?

No. The WhatsApp setting applies only to calls received inside WhatsApp. It does not change calls made to your mobile number through the normal Phone app, and it does not silence other calling apps.

Android and iPhone have separate tools for filtering regular telephone calls. Configure those in the operating system only if you also want to screen unknown calls outside WhatsApp.

Will it mute unknown WhatsApp messages?

No. Silence Unknown Callers affects calls, not messages. An unfamiliar account may still send a chat message unless you block it or use other WhatsApp safety controls.

WhatsApp also offers a separate option for blocking high volumes of unknown account messages under Settings > Privacy > Advanced on supported versions. That feature is intended for unusually high volumes and is separate from call silencing.

Review related WhatsApp privacy controls

Unknown-call screening works best as part of a wider privacy review. In WhatsApp, go to Settings > Privacy and check:

• Who can see your last seen and online status.
• Who can view your profile photo, About information and status updates.
• Who can add you to groups.
• Whether two-step verification is enabled.
• Your blocked contacts.
• Whether app lock or biometric protection is active.

WhatsApp’s built-in Privacy Checkup brings several of these controls together. Follow our guide to use WhatsApp Privacy Checkup for a broader review. If you need to preserve a conversation before changing accounts or clearing content, see how to export a WhatsApp chat without media.

Frequently asked questions

Do silenced WhatsApp calls still show as missed calls?

They remain visible in WhatsApp’s Calls list, allowing you to review the caller and time later.

Does the caller know I silenced the call?

WhatsApp does not send the caller a special notice saying that you enabled Silence Unknown Callers. From their side, the call may appear unanswered.

Does silencing an unknown caller block them?

No. Silencing prevents the call from ringing but does not block or report the account. Use WhatsApp’s Block option for a specific unwanted caller.

Can saved contacts still call me?

Yes. The setting is intended for unknown callers. Saved contacts should continue to ring normally unless other phone or WhatsApp notification settings silence them.

Can I return a silenced call?

Yes. The call remains in the Calls tab. Before returning it, verify that you recognise the person or were expecting contact.

Can I turn the feature off?

Yes. Return to Settings > Privacy > Calls and switch off Silence unknown callers.

Conclusion

To silence unknown callers on WhatsApp, open Settings > Privacy > Calls and enable Silence unknown callers. Unfamiliar calls will stop ringing but remain visible in the Calls tab. For repeated spam or suspicious contact, block or report the specific account instead of relying on silencing alone.
