What does “no caller ID” mean?

Calls that come from an iPhone with “No caller ID” or “Unknown caller” active means that the caller’s phone number is not being transmitted to the recipient’s phone. It can happen for a lot of reasons, such as companies or calling apps blocking caller ID for privacy reasons, while others may do it to conceal their phone number for marketing or other purposes. Some scammers or spammers also use this feature to hide their identities.

In some cases, the call may also be labeled “Blocked” or “Restricted.” When you receive a call from no caller ID, you have the option to accept, decline, or send it to voicemail.

Reasons why someone may want to block calls from unknown numbers

There are many reasons why someone may want to block calls from unknown numbers. These include:

Spam or telemarketing calls

Many people receive unwanted calls from telemarketers or robocalls on a regular basis. Blocking these calls can help reduce the number of unwanted interruptions during the day.


Unknown numbers can also be used by scammers to trap people into giving away personal information or money. Blocking these calls can help protect against potential fraud.

Harassment or stalking

Some individuals may want to block unknown numbers to prevent harassment or unwanted contact from an ex-partner or other person.


Blocking unknown numbers can also be a way to protect one’s privacy. Some people may not want to answer calls from unknown numbers to keep their personal information private.

Avoiding missed calls

Sometimes people may want to block unknown numbers because they are worried about missing an important call from a known contact that may be calling from an unfamiliar number.

Phone number privacy

People may not want to reveal their phone numbers to the caller; blocking unknown numbers can help keep their phone numbers private.

Understanding the iPhone’s built-in call-blocking features

You are lucky if you have an iPhone because it has several built-in call-blocking features that let you restrict calls from specific numbers or contacts. Below are a few of the most commonly used built-in call-blocking features:

Blocked Contacts

This feature allows users to add specific phone numbers or contacts to a blocked list. Once a number is on this list, the user will not receive calls or text messages from that number. To add a contact or number to the blocked list, go to Settings > Phone > Blocked Contacts.

Recent list

Users can also block numbers from the Recents list, which shows all of the recent incoming and outgoing calls on the phone. To block contact from your Recents list, tap the “i” icon which is usually available with the number that you wanna block, and tap “Block this Caller”.

Silence Unknown Callers

This feature, introduced in iOS 13, allows users to silence calls from numbers that are not in their contacts. When this feature is enabled, calls from unknown numbers will go straight to voicemail, and the phone will not ring. You can use this Silence Unknown Callers feature by going to Settings > Phone > Silence Unknown Callers.

Decline Repeated calls

This feature, introduced in iOS 14, allows users to repeatedly decline calls from the same number in a short period. This feature is useful to block robocalls or unwanted calls from scammers. To use this feature, go to Settings > Phone > and turn on the toggle for “Decline Repeated Calls.”

Moreover, It’s worth noting that these built-in call-blocking features do not always block all unwanted calls, and scammers or spammers can use different phone numbers or techniques to get around them. Some users may consider using third-party call-blocking apps for more robust protection.
