How to Identify Unknown Callers Who Block Their Caller-ID

Ever been woken up by an unknown call, only to see “No Caller ID” on your phone screen? Trust me, I’ve been there. It’s frustrating not knowing who’s on the other end. Is it a family member? A work call? Or—worst case scenario—a scammer? Over the years, I’ve learned a few tricks to track down those anonymous callers, and in this post, I’ll share exactly how you can do it too.

If you’re tired of feeling in the dark about who’s calling you, this article will guide you step-by-step on how to identify callers who block their caller ID. You’re not alone in this—whether it’s a hidden number or someone who’s deliberately concealing their identity, I’ve got you covered.

What is a Blocked Caller ID?

So, first things first—what does it mean when you see “No Caller ID” or “Blocked” on your phone? It’s a way for the person calling you to prevent their phone number from showing up. This could be intentional or just the result of using a particular type of phone system.

For example, businesses or marketing agencies often use private numbers to avoid displaying their phone numbers. On the other hand, some scammers and telemarketers love to hide their identities to dodge callbacks. It can get tricky to figure out who’s behind the mystery call.

Why Should You Care About Unknown Callers?

Now, I know what you’re probably thinking—“Do I need to identify every unknown number?” Well, the answer is, it depends. If you’re like me, you probably get at least a handful of calls from numbers you don’t recognize. Some might be important—like job offers or updates from friends. But often, it’s a scam, and we’ve all been there, getting caught in a nasty situation.

I remember one time, I answered a blocked call thinking it was my doctor’s office calling with test results, but it turned out to be a scammer trying to steal my info. Ever since I’ve been super careful about hidden calls, and I’ve learned how to identify them.

How to Identify Unknown Callers Who Block Their Caller-ID

There are several ways you can track down blocked numbers. I’ve tried most of them, so here’s a mix of my personal tips and expert advice from people in the know.

1. Use a Caller ID App

The easiest way to identify a blocked number is to use apps like Truecaller or Hiya. These apps work by crowdsourcing data, meaning that when someone else receives a call from the same number, the app tags it. When you get a similar call, you’ll have a better chance of identifying it.

I remember installing Truecaller after receiving a barrage of scam calls. It helped me filter out most spam and even identified a few of the unknown numbers as legitimate calls from companies I had signed up with.

2. Reverse Phone Lookup

If you have the number, a reverse phone lookup service like Whitepages or BeenVerified can help you identify the caller. Simply input the number into the search bar, and you’ll get details about the caller. It’s not foolproof, but I’ve had some success with it.

3. Contact Your Phone Service Provider

If the mystery call is bugging you, your phone service provider might be able to help. Many service providers have tools that let you trace the call or log a complaint, especially if you’re dealing with harassment or persistent spam calls.

4. Use 67 to Block Your Caller ID

If you’re on the other side of this and want to block your number when calling someone, you can use the *67 feature (just dial *67 before entering the phone number). Interestingly, this is often used by people who want to remain anonymous, but it could be useful if you’re trying to track who is calling you this way.

5. Report the Call

If you get a call from a number that seems suspicious or harassing, don’t hesitate to report it. Most telecom companies have a procedure for this, and some services (like Truecaller) even let you report scam numbers.

My Experience With These Methods

I used to be stressed out every time I saw a “No Caller ID” on my screen. It felt like there was a whole world of unknown calls coming at me. Over time, though, I started using Truecaller, and it immediately identified several of the unknown calls as spam. It felt like a little victory each time I could block one of those scam numbers.

When I didn’t have an app handy, I’d use the reverse phone lookup services. While it wasn’t always accurate, there were times when I found that the mysterious caller was someone important, like a potential client or an old friend trying to reconnect.

Common Mistakes to Avoid When Handling Blocked Calls

While there are plenty of ways to identify blocked callers, there are also a few pitfalls you should watch out for.

1. Don’t Automatically Answer Every Unknown Call

When I first started answering every blocked call out of curiosity or anxiety, I often found myself wasting time. Not every number is important—some are just automated spam calls.

2. Relying Too Much on Caller ID Apps

I love apps like Truecaller, but they’re not perfect. Some numbers might not be identified right away, or they could be misidentified. Always be cautious.

3. Ignoring Your Carrier’s Tools

If you’re getting tons of blocked calls, don’t forget to check with your service provider. Some providers offer specific features to help you block unknown numbers or report them.
