It was a beautiful summer afternoon, and I was out for a walk when my iPhone rang. I glanced at the screen to see who was calling, but to my surprise, the caller ID read “Unknown Caller.”
I hesitated for a moment, wondering who it could be. Should I receive it or let it lend to voicemail? It wasn’t the first time I had received such a call, and I knew I wasn’t alone.
Have you ever experienced the same? Have you ever wondered what it meant when your iPhone displayed “Unknown Caller” as the caller ID? It’s a common dilemma that leaves many iPhone users confused and anxious.
But fear not, as we delve into the mysterious world of “Unknown Caller” on iPhones and explore what it really means. I’ll discuss identifying calls on iPhone, all about unknown caller IDs.
How Calls are Identified on iPhone?
When a call is made, the phone network sends the calling party’s phone number to the receiving party’s network. The receiving party’s phone screen then displays the caller’s phone number using Caller ID technology.
Caller ID retrieves the caller’s name from the CNAM database, which is a database that stores the names and phone numbers of businesses and individuals. This service is usually provided by phone carriers or third-party services.
Phone carriers play a crucial role in identifying callers. They maintain databases of phone numbers, which they use to match incoming calls to subscribers. They also provide CNAM database services to identify callers’ names.
Additionally, they implement various call identification technologies to reduce the number of unwanted and unsolicited calls. Some examples include the SHAKEN/STIR protocol and robocall blocking.
| Method | Description |
|---|---|
| Phone number identification through Caller ID | The phone network shares the caller’s number with the receiver’s network during a call, which displays it on the phone screen using Caller ID technology. |

What is an Unknown Caller id?
Unknown Caller on an iPhone means the recipient can’t see the caller’s phone number or identity. This can be due to the caller blocking their Caller ID, network issues, or spoofing. It’s important to be cautious when answering such calls, as they may not always be unwanted or fraudulent.
Why a caller may appear as unknown
Sometimes, callers may appear as “Unknown” on your iPhone because they have intentionally withheld their number from being displayed. This could be due to privacy concerns or simply because they don’t want you to know who is calling.
Additionally, some phone networks may not be able to display the caller’s information accurately, resulting in the “Unknown” label.
Caller ID blocking
Caller ID blocking is a feature that allows the caller to hide their phone number from being displayed on the recipient’s phone. This is usually done by dialing a code before making the call or by adjusting the phone’s settings.
While this may be helpful in some cases, such as when making anonymous calls for legitimate reasons, it is often associated with telemarketers, scammers, and other unwanted calls.
Spoofing
Spoofing is a technique used by scammers and spammers to manipulate the caller ID information to display a fake number or name. This can be done using various tools and technologies, including VoIP (Voice over Internet Protocol) and robocalling software.
The purpose of spoofing is usually to trick the recipient into answering the call and then scamming them in some way, such as by posing as a representative of a legitimate organization or asking for sensitive information.
How an iPhone Handles Unknown Calls?
When it comes to handling calls from unknown or blocked numbers, iPhones offer several options for managing these calls:
Automatic silence:
This feature allows you to automatically silence all calls from unknown numbers. This means that the call won’t ring and will be sent directly to voicemail without causing any disruption to your day. This feature can be turned on or off in your iPhone settings.
Send unknown callers directly to voicemail:
If you don’t want to completely silence unknown callers, you can choose to send them directly to voicemail. This allows you to screen the call and decide whether or not to respond. You can set this up in your iPhone settings.
Option to allow calls from contacts and repeated calls only:
If you want to receive calls from unknown numbers but only if it’s an emergency, you can choose to allow calls from your contacts or if the same number calls twice within three minutes.
This ensures that you won’t miss any important calls while also filtering out unwanted or spam calls. You can set this up in your iPhone settings under the “Do Not Disturb” section.
Blocking Unknown Callers

How does blocking calls work?
Blocking calls is a feature that allows users to prevent specific phone numbers from calling their phones. When a user blocks a phone number, calls and messages from that number are automatically rejected, and the caller is not able to leave a voicemail.

- Call blocking: This feature is built into most modern smartphones, including the iPhone. Users can manually add phone numbers to their block list, or enable settings to automatically block unknown or hidden callers.

- Third-party call-blocking apps: There are many third-party apps available on the App Store that allow users to block calls and messages from unknown numbers.
Using a third-party app:
Users can download and install third-party apps on their iPhones to block calls from unknown numbers. These apps typically use crowdsourced databases to identify and block spam and scam phone numbers. Some popular third-party call-blocking apps include Truecaller, Hiya, and RoboKiller.
Blocking calls from the Phone app:
The Phone app on the iPhone also has built-in call-blocking features. To block a caller from the Phone app, users can follow these steps:
- Open the Phone app.
- Go to the Recents tab.
- Find the phone number you don’t want to receive calls from and block them and tap the icon of “i” next to it.
- Scroll down and tap “Block this Caller”.
