Receiving calls from “No Caller ID” or “Unknown” numbers on your iPhone can be frustrating and often indicates a spam call. Thankfully, your iPhone offers built-in features and app options to effectively block these unidentified calls and regain control over who can reach you. This guide will show you how to block no caller ID on your iPhone, ensuring a more peaceful and less interrupted day.
Utilizing Silence Unknown Callers to Block No Caller ID
The most direct way to handle calls from numbers not identified as contacts is by using the “Silence Unknown Callers” feature. Introduced with iOS 13, this function intelligently filters calls from numbers that are not in your contacts, recent outgoing calls, or Siri Suggestions. This is particularly effective for blocking “No Caller ID” calls as these calls inherently originate from numbers not recognized by your phone.
To activate “Silence Unknown Callers,” follow these simple steps:
- Open the Settings app on your iPhone.
- Scroll down and tap on Phone.
- Find and select Silence Unknown Callers.
- Toggle the switch to the On position.
Once enabled, calls from unknown numbers will be automatically silenced and routed directly to voicemail. These calls will still be visible in your recent calls list, allowing you to check voicemails and return calls if necessary. Importantly, calls from saved contacts, numbers you’ve recently called, and numbers found in your emails or messages through Siri Suggestions will still ring through as normal.
It’s worth noting that if you make an emergency call, “Silence Unknown Callers” will be temporarily disabled for 24 hours. This ensures that you can be reached back if needed in emergency situations.
Before turning on this feature, consider if you are expecting calls from numbers not yet in your contacts. While voicemails are still an option, you will not receive real-time notifications for silenced calls.
Employing Third-Party Apps for Enhanced Call Blocking
For a more robust approach to blocking “No Caller ID” and spam calls, you can leverage third-party apps designed for call filtering and identification. These apps often use extensive databases of spam numbers and sophisticated algorithms to identify and block unwanted calls, potentially offering more advanced features than the built-in “Silence Unknown Callers.”
Here’s how to set up a call blocking app on your iPhone:
- Navigate to the App Store on your iPhone.
- Search for and download a reputable call blocking app. Look for apps with high ratings and positive user reviews. Several apps are available, offering varying features and subscription models.
- After installation, go back to Settings and tap on Phone.
- Select Call Blocking & Identification.
- Under “Call Identification Apps,” you will see a list of installed call blocking apps. Enable the app you wish to use by toggling the switch next to it to the On position.
You can activate multiple call blocking apps simultaneously and prioritize their order by tapping “Edit” and dragging them into your preferred sequence. When a call comes in, your iPhone will consult these apps to identify potential spam or “No Caller ID” calls. The app may label the call (e.g., “Spam,” “Telemarketing,” or “Potential Scam”) or even automatically block it based on its settings. No personal call information is shared with third-party app developers during this process.
If you find that a specific number, even if labeled “No Caller ID,” is consistently a spam caller, you also have the option to manually block the number directly in your iPhone’s settings under “Blocked Contacts.”
By using either “Silence Unknown Callers” or a combination of third-party apps, you can significantly reduce the number of disruptive and unwanted “No Caller ID” calls you receive on your iPhone, leading to a more focused and less interrupted mobile experience.
