How to Find No Caller ID on iPhone: A Complete Guide

Getting a call from "No Caller ID" on your iPhone can be frustrating, especially if you want to know who’s trying to reach you. These calls hide the caller’s number, making it tricky to call back or identify them. But don’t worry—there are ways to figure out who’s behind these calls.

To find No Caller ID on iPhone, you can use the *69 code to redial the last call, download a caller ID app like Truecaller, or enable settings to manage unknown calls. This guide will walk you through each step clearly how to find no caller ID on iPhone.

What Does “No Caller ID” Mean?

When your iPhone shows “No Caller ID,” it means the person calling has hidden their phone number. This could be for privacy reasons, like a doctor’s office protecting patient information, or sometimes scammers trying to avoid being identified.

These calls appear in your Phone app’s Recents tab, but tapping the “i” next to them won’t show a number or name—just “No Caller ID” or “Unknown.” Knowing this helps you understand why you can’t call them back directly, but there are still ways to find out who they are.

How to Find No Caller ID on iPhone

Let’s dive into the two main methods to identify No Caller ID calls: using the *69 code and installing a caller ID app.

Method 1: Use the *69 Code to Redial the Last Call

One of the easiest ways to try identifying a No Caller ID call is by using a special code called *69. This code works on most iPhones and major carriers like AT&T, T-Mobile, and Verizon in the United States and Canada. It redials the last incoming call, even if the number was hidden, and sometimes reveals the actual phone number.

Here’s how to do it:

  1. Open the Phone App: Go to the Phone app on your iPhone’s home screen.
  2. Go to the Keypad: Tap the “Keypad” tab at the bottom of the screen.
  3. Dial *69: Type *69 (that’s star, then six, then nine).
  4. Press Call: Hit the green call button to redial the last incoming call.
  5. Check the Number: If the call connects, the real phone number may appear on your screen. If you don’t want to talk, quickly press the red “End” button.

Important Notes:

  • This method only works for the most recent call, so act fast after receiving a No Caller ID call.
  • It doesn’t always work, especially if the caller used advanced blocking methods.
  • Success depends on your carrier and the caller’s settings.

If *69 doesn’t reveal the number, don’t worry—there’s another method to try. For more ways to manage calls, see How to Block Spam Calls on iPhone in 2025.

Method 2: Download a Caller ID App

Another effective way to identify No Caller ID calls is by using a caller ID app. Apps like Truecaller compare incoming calls against a large database to show who’s calling, even if the number is hidden. These apps need to be installed before the call comes in, so they won’t work for past calls.

Here’s how to use a caller ID app:

  1. Open the App Store: Find the App Store on your iPhone and tap it.
  2. Search for a Caller ID App: Type “caller ID” in the search bar. Popular options include Truecaller or Hiya.
  3. Download and Install: Choose a trusted app like Truecaller (look for high ratings, like 30,000+ reviews) and install it. Many are free, but some offer premium features.
  4. Set Up the App: Follow the app’s instructions to grant permissions, like access to your calls.
  5. Receive Calls: Once installed, the app will automatically identify incoming calls, showing the caller’s name or marking it as spam if it’s in their database.

Tips for Choosing an App:

  • Pick apps with high ratings and many downloads to ensure reliability.
  • Avoid paying for apps until you’re sure they work for you—many free versions are effective.
  • Apps only identify calls received after installation, not past ones.

Truecaller is a great choice because it also lets you block spam calls. For more on blocking unwanted calls, check out How to see blocked numbers on iPhone.

Managing No Caller ID Calls

If you keep getting No Caller ID calls and want to stop them, your iPhone has built-in tools to help. Here are two ways to manage these calls.

Silence Unknown Callers

This feature sends calls from numbers not in your contacts, including No Caller ID calls, straight to voicemail. It’s a simple way to avoid interruptions.

  1. Open Settings: Tap the Settings app on your iPhone.
  2. Go to Phone: Scroll down and tap “Phone.”
  3. Enable Silence Unknown Callers: Find “Silence Unknown Callers” and toggle it on.

Now, unknown calls won’t ring but will show up in your Recents tab and voicemail. This is perfect if you only want calls from people you know.

Block No Caller ID Calls

If you want to block a specific No Caller ID call:

  1. Open the Phone App: Go to the Recents tab.
  2. Find the Call: Look for the “No Caller ID” entry.
  3. Tap the Info Icon: Tap the “i” next to the call.
  4. Block the Caller: If the option is available, tap “Block this Caller.”

Note that blocking may not always work for No Caller ID calls since the number is hidden, but it’s worth trying for persistent callers.

How to Show Your Own Caller ID

If you’re making calls and they show up as “No Caller ID” on other people’s phones, you might have accidentally turned off your caller ID. Here’s how to fix it:

  1. Go to Settings: Open the Settings app.
  2. Tap Phone: Scroll and select “Phone.”
  3. Check Show My Caller ID: Tap “Show My Caller ID” and make sure the toggle is on.

If the toggle is stuck or spinning, there might be a software issue. Try resetting your network settings:

  1. Go to General: In Settings, tap “General.”
  2. Select Transfer or Reset iPhone: Scroll to the bottom and tap it.
  3. Choose Reset: Tap “Reset,” then “Reset Network Settings.”
  4. Enter Your Passcode: Confirm and wait for the reset to finish.

This resets Wi-Fi, Bluetooth, and cellular settings, so you’ll need to reconnect to networks afterward. For more on network settings, see iPhone Wi-Fi Settings.

Comparison of Methods to Find No Caller ID

Here’s a table to help you decide which method works best for you:

Method Pros Cons
*69 Code Free, quick, works on most carriers, no app needed Only works for the last call, not always reliable, carrier-dependent
Caller ID App (e.g., Truecaller) Identifies callers and spam, reliable for future calls, often free Requires prior installation, may need permissions, won’t work for past calls
Silence Unknown Callers Built-in iPhone feature, no cost, reduces interruptions Sends all unknown calls to voicemail, may miss important calls
Block No Caller ID Free, easy to use for specific calls May not work for all hidden numbers, limited effectiveness

Why Do People Hide Their Caller ID?

People hide their caller ID for various reasons. Some are legitimate, like businesses protecting client privacy or individuals avoiding unwanted callbacks. Others might be telemarketers or scammers trying to trick you into answering. Knowing this can help you decide whether to pursue identifying the caller or simply ignore the call.

Troubleshooting Common Issues

Sometimes, things don’t work as planned. Here are solutions to common problems:

  • *69 Doesn’t Show the Number: If *69 fails, the caller may have used a stronger blocking method, or your carrier doesn’t support it. Try a caller ID app instead.
  • Caller ID App Not Identifying Calls: Ensure the app is installed and permissions are granted before the call. Test with a new call to confirm it’s working.
  • Show My Caller ID Toggle Stuck: Reset network settings as described above. If the issue persists, restart your iPhone or update to the latest iOS version.

FAQ: Common Questions About No Caller ID on iPhone

1. Can I find out who called me with No Caller ID after a long time?

No, neither 69 nor caller ID apps can identify past No Caller ID calls. 69 only works for the most recent call, and apps like Truecaller need to be installed before the call comes in.

2. Is the *69 code free to use?

Yes, dialing *69 is usually free, but check with your carrier to confirm, as some may charge for call return services.

3. Will caller ID apps work for all No Caller ID calls?

Not always. Apps like Truecaller rely on their database, so they may not identify every hidden number, especially if it’s not in their system.

4. How do I stop No Caller ID calls completely?

Enable “Silence Unknown Callers” in Settings > Phone to send these calls to voicemail. You can also block specific calls in the Recents tab, but this may not work for all hidden numbers.

5. Why does my iPhone show my calls as No Caller ID?

Your caller ID might be turned off. Go to Settings > Phone > Show My Caller ID and toggle it on. If it’s stuck, reset network settings.

Final Thoughts

Dealing with No Caller ID calls on your iPhone doesn’t have to be a mystery. By using the 69 code, installing a caller ID app like Truecaller, or managing calls with iPhone settings, you can identify or block these calls easily. Try the 69 method first since it’s quick and free, then consider an app for ongoing protection.

If you want to stop these calls altogether, enable “Silence Unknown Callers” or block them in your Recents tab. With these tools, you’ll have more control over your phone and peace of mind.
