How Do Callers Hide Their Phone Number?

First, how do these people hide their phone numbers when they call you?

Anyone can hide their number because of the No Caller ID feature. When you make this type of call, you appear as an Unknown Caller. All that it takes is entering a few digits.

Enter *67 before the number that you wish to call. This action will automatically block your caller ID. The number you dial would look like this: *67-555-555-0000.

The No Caller ID feature usually gets used to prevent tracking. However, some people misuse it for harassment and other illegal activities. That’s why you need to learn how to unmask the caller’s number.

The following section shows you how to reveal an unknown caller.


Block Specific Numbers

Once you figure out an unknown caller’s number, you will be able to block them by using your smartphone’s features with ease.

How to Block Specific Numbers on iPhone

Apple iPhone users can easily block calls by following these instructions:

  1. Open the “dialer” on your iPhone and scroll to the number you’d like to block.
  2. Tap the “i” with a circle around it located to the right of the number.
  3. Scroll down and choose “Block Caller.”

Once this happens, the caller will only receive a message stating that you’re not accepting calls or something of that nature.

How to Block Specific Numbers on Android

Android instructions vary depending on make, model, and software version, but the instructions should be pretty similar for most phones.

  1. Launch the phone’s dialer.
  2. Tap on the “phone number” located in the “Recents” tab in your call log.
  3. Click the “i” with a circle around it.
  4. Tap “Block” at the bottom of the screen.
  5. Select “Confirm.”

Although you’ve blocked the number that is calling, the user of that number will never know. They will receive a message similar to a disconnected phone.

2. Answer Correctly

Android phones let you answer calls in different ways. On some devices, you have to swipe up on the answer (or green) button, while others make you swipe right. Try both methods.

If you have a Samsung phone, things are a bit different now. Earlier, one could tap on the answer (or green) button to accept the call. But the functionality has been removed now. So if you are trying to answer the call in the same way, it’s incorrect. You will have to swipe up on the green button.

In case you want the Tap to answer feature back, y

In case you want the Tap to answer feature back, you can do that by going to Settings on your Samsung phone. Then, go to Accessibility > Interaction & Dexterity>Assistant Menu. Turn on the toggle next to off on the next screen. Then, you will find the Single tap to swipe option. Enable it. Now, you can answer calls with a single tap.

Even though you get the feature, enabling the Assi

Even though you get the feature, enabling the Assistant Menu has a drawback as it adds a floating menu icon. To hide that, increase the Transparency of the menu in the settings. Alternatively, long-tap the floating icon and drag it towards the Hide button that appears. It will then stay in your notification panel.

Clue #2: The Number of Rings

If you hear only one ring or no ring at all before your call goes to voicemail, this is a good indication you’re blocked. In this case, the person has used the number blocking feature on their phone. If you call once a day for a few days and get the same result each time, that is strong evidence your number is blocked. If you hear three to five rings before your call routes to voicemail, you’re probably not blocked (yet), however, the person is declining your calls or ignoring them.

Exceptions: If the person you’re calling has the Do Not Disturb feature turned on, your call – and everyone else’s – will be quickly routed to voicemail. You will also get this result when their phone battery is dead or their phone is turned off. Wait a day or two before calling again to see if you get the same result.

Alternate Way to Answer Calls

If the touch buttons do not let you answer calls, you can use the hardware buttons to answer calls. While the Power key lets you end the call, the volume up key can be used to answer calls. The latter feature is limited to some phones only.

To enable physical buttons, go to Settings > Accessibility. You will find the required options. Alternatively, open the Settings for the Phone app. Then, go to Answering and ending calls. Enable the required buttons.

Third-party Apps (Samsung Galaxy)

As you might know, neither Samsung Galaxy nor OnePlus devices don’t have the ability to block numbers of strangers in their built-in native dialers. For such unique phones and tablets the only option is to use a third-party call managing app. We can suggest the Call Blocker by Vlad Lee that can be easily found in the Google Play Store.

All you need to do is:

  • Install the app.
  • Launch it.
  • Give it all required permissions.
  • Go to the Blocking tab.
  • Make sure the Blocking itself is toggled on.
  • Activate the Unknown numbers (Block all numbers except contacts) option: Once you’ve configured the app, all calls from strange numbers will be rejected. 

According to user feedback as of May 2020, this app doesn’t cope with call filtering on OnePlus devices. We’d appreciate if you gave us your feedback concerning the issue in the comments.

Why don’t calls work after changing my Android device name?

Start by unpairing your Android device from your PC. Go to Start  > Settings > Devices > Bluetooth & other devices > Other devices). In your Android device settings (typically under the About your device page), change the name to the one you want. Then, go back to your PC’s Bluetooth settings and pair your phone again to establish the connection with your phone’s updated name.

What You Can Do When Someone Blocks Your Number

While you can’t do anything to have the block on your number removed with their wireless carrier or from their phone, there are a couple of ways to get through or verify your number is, indeed, blocked. If you try one of the options below and get a different result or clue from the list above (provided they don’t answer), take it as evidence that you’ve been blocked.

  • Use *67 to hide your number from their caller ID when you call.
  • Hide your number using the settings in your phone to turn off your caller ID information on outgoing calls.
  • Call them from a friend’s phone or have a friend you trust call them for you.
  • Contact them directly through social media or email and ask if they’ve blocked you.

Another way to circumvent a block is to use a virtual phone number or internet calling service, something you can get with free internet phone call apps.

When a different number is being used to make the outgoing call, the recipient's phone will see that new number, not your real one, thus avoiding the block. 

Repeatedly contacting someone who has taken steps to cut contact, such as blocking your number, could result in accusations of harassment or stalking and serious legal consequences.
