How to Block No Caller ID Calls on Your Verizon iPhone

Receiving calls labeled as "No Caller ID" can be frustrating and intrusive. Fortunately, there are several methods to block these calls on your Verizon iPhone.

What Are No Caller ID Calls?

"No Caller ID" calls occur when the caller intentionally hides their phone number, making it appear as if the call is coming from an unknown or private number. These calls are often associated with telemarketers, scammers, or robocallers.

How Can I Block No Caller ID Calls on My iPhone?

1. Enable Silence Unknown Callers

iOS offers a built-in feature called "Silence Unknown Callers" that silences calls from numbers not in your contacts, recent calls, or Siri Suggestions. To activate this feature:

  1. Open the Settings app.
  2. Scroll down and tap Phone.
  3. Toggle on Silence Unknown Callers.

This will send calls from unknown numbers directly to voicemail without ringing your phone. However, be aware that legitimate calls from unknown numbers will also be silenced.

2. Use Do Not Disturb Mode

Another method is to use the Do Not Disturb (DND) feature:

  1. Go to Settings > Focus > Do Not Disturb.
  2. Under Allowed Notifications, tap People.
  3. Select All Contacts.

With DND enabled, calls from numbers not in your contacts will be silenced and sent to voicemail. Remember to turn off DND when expecting calls from unknown numbers.

3. Create a Blocked Contact for No Caller ID

You can create a contact with a dummy number to block No Caller ID calls:

  1. Open the Phone app and tap Contacts.
  2. Tap the + icon to add a new contact.
  3. Enter "No Caller ID" as the name and "000-000-0000" as the phone number.
  4. Save the contact and then block it.

This method will block calls from numbers that appear as "No Caller ID."

4. Use Verizon's Call Filter App

Verizon offers a Call Filter app that helps identify and block spam calls:

  • Features:
  • Identify suspected spam calls with alerts.
  • Automatically block high-risk spam calls.
  • Report phone numbers as spam.
  • Adjust spam filter settings anytime.

The app is available for free on the App Store. For enhanced features, Verizon offers a premium version called Call Filter Plus, which includes Caller ID and blocking neighborhoods. Eligible customers get a 15-day trial for Call Filter Plus. After the trial, it costs $3.99 per month, per line. (apps.apple.com)

5. Consider Third-Party Call Blocking Apps

Several third-party apps can help block No Caller ID calls:

  • Hiya: Spam Blocker & Caller ID: Blocks spam calls and messages, providing security against unwanted calls. Some features may require a subscription. (appshunter.io)

  • Truecaller: Premium Caller ID: Identifies unknown numbers and blocks spam calls. Offers a free version with basic features and a premium subscription for full functionality. (appshunter.io)

6. Contact Verizon for Additional Support

If unwanted calls persist, consider reaching out to Verizon's customer support for further assistance. They may offer additional services or guidance to help manage and block unwanted calls.

Conclusion

Blocking No Caller ID calls on your Verizon iPhone can be achieved through built-in features, Verizon's Call Filter app, or third-party applications. Each method has its advantages, so choose the one that best fits your needs to enjoy a more peaceful and secure calling experience.
