Receiving repeated WhatsApp calls from numbers you do not recognise can be distracting and, in some cases, concerning. Spam calls, promotional messages and suspicious callers have become common across communication platforms, making privacy controls increasingly important for smartphone users.
WhatsApp offers a built-in privacy feature called Silence Unknown Callers that can help reduce these interruptions. Once enabled, calls from unknown numbers will no longer ring on your phone. Importantly, the feature does not completely block those calls. They will still appear in WhatsApp's Calls tab, allowing you to review them later and decide whether the caller was genuine.
This feature can be particularly useful for people who frequently receive unwanted calls but do not want to completely block every number that is not saved in their contacts.
What Does Silence Unknown Callers Do on WhatsApp?
The feature is designed to prevent calls from unknown accounts from disturbing you. When an eligible unknown caller tries to reach you through WhatsApp, the incoming call is automatically silenced instead of ringing normally.
The call can still be recorded in your WhatsApp call history. This means you can open the Calls section later, check the number and determine whether you need to return the call.
It provides a middle ground between allowing every incoming WhatsApp call to ring and completely blocking unknown callers.
How to Silence Unknown WhatsApp Calls
You can activate the feature directly through WhatsApp's privacy settings. The process takes only a few steps:
- Open WhatsApp on your smartphone.
- Go to Settings.
- Select Privacy.
- Scroll to and open the Calls section.
- Look for Silence Unknown Callers.
- Turn the option ON.
Once activated, WhatsApp will silence qualifying calls from unknown callers instead of allowing them to ring normally.
The exact appearance or placement of these settings can vary slightly depending on your WhatsApp version and whether you are using Android or iPhone. Keeping WhatsApp updated can help ensure that the latest privacy and security options are available.
Does This Feature Block Unknown Numbers?
No. This is an important distinction.
Turning on Silence Unknown Callers does not work in the same way as blocking a WhatsApp account. The feature primarily prevents unknown incoming calls from ringing and disturbing you.
Information about the call can still appear in the Calls tab. You can therefore review your recent call history and identify the number later.
This can be helpful if the call came from someone genuine whose number you had not saved, such as a delivery representative, business contact or another person trying to reach you for the first time.
What If the Same Unknown Number Keeps Calling?
Silencing unknown calls may reduce interruptions, but it does not necessarily stop someone from attempting to contact you.
If a particular number repeatedly calls you or appears suspicious, WhatsApp provides additional options such as Block and Report.
Blocking prevents the account from contacting you through normal WhatsApp messages and calls. Reporting can also send relevant information to WhatsApp for review, making it useful when you suspect spam, scams or abusive behaviour.
Users should consider blocking or reporting numbers that repeatedly cause problems rather than responding to suspicious callers.
Be Careful With Calls From Unfamiliar Numbers
Unknown WhatsApp calls can sometimes be associated with scams or attempts to obtain personal information. Users should therefore be cautious when answering unexpected calls, particularly when the caller asks for financial information, OTPs, UPI PINs, passwords or other confidential details.
Never share an OTP, banking password, card PIN or UPI PIN with someone simply because they claim to represent a bank, government department, courier company or another organisation.
If a caller makes an urgent financial demand or asks you to install an unfamiliar application, verify the request independently through the organisation's official channel before taking action.
A Simple Privacy Setting That Can Reduce Interruptions
WhatsApp's Silence Unknown Callers feature is useful for users who want fewer interruptions without completely losing visibility of incoming calls from unfamiliar numbers.
The key difference is simple: silencing is not the same as blocking. Unknown calls can be prevented from ringing while their details remain available in the Calls tab for later review.
If you frequently receive unwanted WhatsApp calls, enabling this privacy option can make everyday use of the app quieter and easier to manage. And when a particular caller becomes persistent or suspicious, the Block and Report tools provide an additional layer of control.
