‘No Caller ID’ vs. ‘Unknown Caller’: What do these terms mean and what’s the difference?

When you see “No Caller ID” or “Unknown Caller” pop up on your phone screen, it can be a bit unnerving. Who could it be? Is it someone you know, or is it something more suspicious? Let’s dive into what these terms mean and how you can handle them.

What’s No Caller ID?

When your phone shows “No Caller ID,” it means the person calling you has deliberately hidden their information. This could be totally innocent, like when a friend wants to keep their number private. However, it could also be a telemarketer or even a scammer trying to reach you.

Who Uses No Caller ID?

People use No Caller ID for various reasons. Celebrities might want privacy, while telemarketers might use it to avoid direct call-backs. Unfortunately, scammers also exploit this feature to conceal their identity.

How Does No Caller ID Work?

Setting up No Caller ID is pretty straightforward. You can do it for just one call or all calls. For a single call, dial *67 before the number. To hide your caller ID for all calls, you can adjust settings on your phone.

What’s Unknown Caller?

“Unknown Caller” is a bit different from “No Caller ID.” It means your phone service provider doesn’t recognize who’s trying to reach you. This could be due to network issues or settings on your phone carrier’s end.

How to Manage Anonymous Calls:

If you’re wary of answering No Caller ID or Unknown Caller calls, you’re not alone. On iPhones, you can silence these calls to avoid disturbances. Android phones offer options to block unknown callers altogether.


While some No Caller ID or Unknown Caller calls might be harmless, it’s essential to stay cautious, especially with the rise of scams. By understanding these terms and managing your phone settings, you can protect yourself from unwanted calls and maintain your privacy.


1.Are No Caller ID calls always suspicious?

No, not necessarily. While some may be harmless, it’s crucial to remain cautious, especially if you’re not expecting a call from someone without caller ID.

2.Can I block all Unknown Caller calls on my phone?

Yes, on Android phones, you can typically block unknown callers by adjusting settings in your phone app. However, keep in mind that this might affect legitimate calls from numbers not in your contacts.

3.Is it safe to silence Unknown Caller calls on my iPhone?

Silencing Unknown Caller calls can help avoid disturbances, but be mindful of potential missed calls from important contacts. Consider leaving voicemail enabled for unknown callers to ensure you don’t miss any critical messages
