Struggling with mysterious calls? Wondering “How to Find No Caller ID on iPhone”? You’re not alone! Unmasking unknown callers can be crucial for avoiding spam or identifying important contacts.

In this guide, we’ll reveal effective methods to trace these elusive numbers and regain control over your calls. Say goodbye to the frustration of unknown callers and hello to peace of mind!

Let’s jump in and figure out how to unmask these unknown callers!

What Is No Caller ID and How Does It Work?

No caller ID is a feature that lets people hide their phone numbers when making calls. So, instead of seeing the caller’s number on their phone screen, the recipient will either see “No Caller ID,” “Private Number,” or just a space after the previous caller’s number. 

This helps maintain the caller’s privacy by keeping their phone number hidden from the person they’re calling.

How People Can Hide Their Caller IDs on iPhones

Here are a few ways you can hide your caller ID:

Caller ID Blocking Services

Many phone carriers provide services that let their customers block their phone numbers from being shown to the people they call. It’s a built-in feature that users can toggle on or off according to their preferences. 

By enabling this feature, the caller’s phone number will not be displayed on the recipient’s phone when making outgoing calls. This offers users greater control over their privacy and who can see their contact information.

Third-Party Apps

Various apps let users make calls using fake, disposable, or Internet-based numbers, effectively masking their real phone numbers.

Caller ID Spoofing

This means that the number displayed on the recipient’s phone is entirely different from the actual number the call originated from.

While there are legitimate reasons for concealing caller IDs, such as maintaining privacy, this tactic is often abused by scammers, telemarketers, and pranksters who wish to identify unknown numbers to avoid being identified or tracked.

As a result, it can be considered a shady tactic when used for deceptive or malicious purposes.

How to Find No Caller ID on iPhone

Here are some reliable ways to uncover the identities of those annoying no-caller ID callers on your iPhone.

Dial the *69 Code to Track Unknown Caller IDs

The *69 code can help you trace call history to the last incoming call, even if the number was blocked or private. Here’s how it works:

  1. Immediately after receiving a call from an unknown or no-caller ID number, dial *69 on your iPhone’s keypad.
  2. Press the call button, and an automated voice recording will provide you with the caller’s phone number and any additional information available, such as their name and address (if listed in a public directory).
  3. You can then choose to call back the number or take further action as needed.

Keep in mind that some carriers may charge a small fee for using the *69 service, so it’s always wise to check with your provider first.

Dial the *57 Code to Track Unknown Caller IDs

If you’ve received a harassing, threatening, or otherwise concerning call from a no-caller ID number, dialing *57 is your best bet. This code not only traces the call but also alerts your phone company and potentially local law enforcement authorities.

Here’s how to use the *57 code:

  1. After receiving the concerning call, dial *57 on your iPhone’s keypad.
  2. Follow the automated voice prompts, providing any additional information requested.
  3. Your phone company will receive a record of the call, including the audio recording and the caller’s number (if available), which may be forwarded to the appropriate authorities for investigation.

Note that using the *57 service often incurs a charge from your carrier, so it’s essential to use this option judiciously and only when necessary.

Use a Third-Party Service or App

If your iPhone doesn’t offer the 69 or 57 services, or if you’d prefer a more comprehensive solution, consider using a third-party app or online service designed to reveal unknown caller IDs. 

These tools typically perform a reverse phone lookup, scouring public databases, social media platforms, and other online sources to uncover details about the caller’s identity.

Here are some popular options to consider:

  • TrapCall: This app intercepts calls from unknown numbers, redirecting them through its servers to unmask the unknown caller’s number. It also offers features like call blocking, voicemail transcription, and call recording.
  • TrueCaller: This app uses a crowdsourced directory matching incoming calls against a database of known numbers to identify unknown callers and automatically block spam calls.

While these apps offer free basic features, more comprehensive lookup capabilities often require a paid subscription.

How to Block Calls From Unknown Callers on Your iPhone

If you’re primarily interested in avoiding calls from unknown or no-caller ID numbers rather than the person calling or identifying them, you can adjust your iPhone’s settings to silence or block these calls altogether.

Here’s how to silence unknown callers on your iPhone:

  1. Open your Phone Settings app.
  2. Scroll Down and Tap “Phone.”
  3. Select “Silence Unknown Callers”
  4. Toggle on the “Silence Unknown Callers” option.

This silence calls from unknown callers feature will prevent your iPhone from ringing for any incoming calls from numbers not saved in your contact list, although the unknown callers can still leave voicemails.

To take it a step further and to block unknown callers entirely, follow these steps:

  1. Open the Phone app and tap “Contacts.”
  2. Select the “+” icon to add a new contact.
  3. Enter “No Caller ID” or a similar name, and add the phone number you wish to block (if known).
  4. Tap “Block this Caller” and confirm.

Repeat this process for any additional numbers you want to block. Keep in mind that blocking an unknown number of callers may prevent you from receiving legitimate calls from new or unsaved numbers, so use this option judiciously.

Contact Your Phone Service Provider

If all else fails, reach out to your phone service provider’s customer support team. They may offer additional call tracing services or be able to provide you with the caller’s information, even for no-caller or unknown caller ID numbers.

Some phone service providers also allow you to request a detailed call log that includes unmasked phone numbers for all incoming and outgoing calls, which can help identify persistent unknown callers.

While these services often come at an additional cost, they can be invaluable if you’re dealing with a persistent or concerning issue with an unknown caller number or callers.
