What Does No Caller ID Mean?

A No Caller ID call is one where the caller intentionally hides their phone number using built-in phone settings, third-party apps, or carrier services. Unlike calls from an unknown caller—which occur when the network fails to recognize a number—caller ID calls without a visible number are deliberately masked.

You might wonder why people use no caller ID. Well, there are both legitimate and questionable reasons for making calls from unknown numbers. Some common reasons include:

• Privacy Protection – Businesses, journalists, or professionals may use internet telephony and power dialer systems to keep their numbers private.
• Outbound Call Strategy – Some telemarketers and sales teams use workflow automation to contact leads while masking numbers.
• Avoiding Callbacks – Individuals may use no caller ID to prevent missed calls from being returned.
• Spam & Scams – Fraudsters and robocalls often use hidden numbers to evade call filtering and call labeled detection.

How to Call No Caller ID?

Getting calls from a No Caller ID number can be frustrating, especially if you suspect it’s important or just want to know who’s calling. Since these callers intentionally hide their caller information, calling them back isn’t as simple as redialing. However, there are a few effective ways to uncover and return these anonymous calls.

1) Using *69 to Call No Caller ID Back

One of the easiest ways to return a call with No Caller ID is by dialing *69 immediately after missing the call. This service, known as “Last Call Return,” redials the last incoming number, even if it is private. It works on most landlines and some mobile carriers, though availability varies.

You simply need to:

• Dial *69 and tap the call button
• You will receive a voice recording that reveals the last caller ID

If the call is still active, it may connect you directly to the caller. However, this method is not foolproof—if the caller uses advanced call filtering or internet telephony, the number may remain hidden.

💡 Pro Tip: If you receive calls on your iPhone or calls on your Android, check with your carrier to see if *69 is supported.

2) Using Call Tracking and Third-Party Apps

If *69 doesn’t work, third-party apps can help you identify and return calls from hidden numbers.

✅ Reverse Phone Lookup Apps: Applications like Truecaller and Hiya analyze patterns from spam calls and flag anonymous calls. Truecaller offers caller ID services and spam blocking, while Hiya provides real-time spam detection and caller identification.

✅ Call Monitoring Services: Tools such as CallApp integrate with CRM systems to track and store incoming calls, including those labeled as private. CallApp offers caller ID, call blocking, and call recording features, providing background information about incoming or outgoing calls.

✅ Call Recording Apps: While they don’t directly reveal the number, apps like Call Recorder – Automatic Call Recording (ACR) help gather details that may assist in identifying unknown calls by recording conversations for later analysis.

✅ Power Dialer Tools: Business-focused services like PhoneBurner integrate with workflow automation for better call management and number tracking, enhancing efficiency in handling large volumes of calls.

3) Contacting Your Carrier

Many carriers offer call handling features that let you trace or return No Caller ID calls. You can:

📌 Request call tracing services from your provider, which may log the hidden number for legal purposes.

📌Differentiate between blocked and unavailable numbers, as some carriers offer caller ID vs call mean features.

📌Report the calls for investigation if they are harassing or fraudulent.

💡 Did You Know? Some providers allow you to enable call filtering that forces unknown callers to reveal their identity before connecting.

4) Using Call Forwarding or Voicemail Traps

A clever way to capture caller information is by redirecting calls from unknown numbers to a voicemail service or a second number.

🔹 Set up call forward rules that route unwanted calls to another phone with call recording enabled.

🔹 Use a secondary number (via third-party apps) to trick the caller into leaving their real number.

🔹 Some call transfer methods allow for rerouting calls to a service that unmasks blocked numbers.

How to Call From No Caller ID?

Calling from No Caller ID can be useful for privacy, security, or simply maintaining anonymity. If you want to make a call without revealing your phone number to the recipient, there are several ways you can hide your caller ID.

I) Using *67 to Block Your Caller ID

The easiest and most common method to call from No Caller ID is by dialing *67 before entering the phone number.

• How it works: When you dial *67 before the number, it will block your caller information for that specific call.
• Availability: This method works on both iPhones and Android devices and is supported by most mobile carriers.
• Limitations: It only blocks your number for one call. If you make another call, you’ll need to use *67 again.

Example: Dial *67 + phone number, such as *67 123-456-7890. This will ensure your number is hidden from the person you’re calling.

II) Enable Caller ID Block in Your Phone Settings

Another option is to block your caller ID permanently or temporarily by adjusting the settings on your phone.

• For iPhone: Go to Settings > Phone > Show My Caller ID, then toggle the switch to off. This will hide your number for all outgoing calls.
• For Android: Go to Settings > Call > Additional Settings > Caller ID, and select Hide Number.

Note: Some carriers may charge an additional fee for permanently hiding your caller ID, so it’s worth checking with your provider.

III) Using Third-Party Apps for Private Calls

There are several third-party apps that allow you to make calls from a No Caller ID number, offering additional features like text messaging and call recording.

• Burner: Burner allows you to create temporary phone numbers for private calls and texts. It’s ideal for situations where you don’t want to reveal your personal number.
• Hushed: Hushed offers a similar service, providing you with disposable numbers for private or anonymous calls.
• Google Voice: Google Voice lets you make calls from a different number, allowing you to keep your personal number hidden.

IV) Using a VoIP or Internet Telephony Service

If you’re looking for a more tech-savvy approach, you can use a VoIP (Voice over Internet Protocol) service to make calls from a No Caller ID number.

• Examples of VoIP services include Skype, Google Voice, or WhatsApp, where you can hide your number when making outgoing calls.
• How it works?: These services allow you to call without revealing your personal number, as they use internet connections to place calls.

V) Contact Your Carrier for Permanent Caller ID Blocking

If you want to ensure your number is always blocked when making calls, some carriers offer permanent caller ID blocking options. Contact your carrier to inquire about this feature, which can be applied to your entire account.

It works for all outgoing calls, including international calls or call transfers.

What are the Risks of Calling Back No Caller ID Numbers?

Returning a No Caller ID call can expose you to scams, spam, and unnecessary risks. Here’s why you should think twice:

1️⃣ Scam and Fraud Risks

Many hidden calls are linked to online scams, phishing attempts, or caller ID spoofing. Scammers may impersonate banks, government agencies, or tech support to steal personal information.

2️⃣ More Spam and Telemarketing Calls

Calling back confirms your number is active, leading to more spam calls, text messaging spam, and unwanted solicitations.

3️⃣ Costly International Call Charges

Some hidden calls originate from international numbers that charge high fees when you call back, commonly known as Wangiri scams.

4️⃣ Risk of Harassment

Returning a call could expose you to harassment, stalking, or repeat spam calls from aggressive marketers or fraudsters.

5️⃣ Call Tracking and Monitoring

Scammers use call monitoring tools to track your activity, verify your number, and manipulate responses using conversational AI.

Tips For Handling No Caller ID Calls Safely?

• Enable “Silence Unknown Callers” – This feature, available on iPhone and Android, filters out calls from numbers not in your contacts, reducing spam and scam risks.

• Check Who’s Calling Before Answering – Reverse phone lookup apps like Truecaller or Hiya can help identify hidden or suspicious numbers, preventing you from engaging with potential scams.
• Dial *69 to Call Back Safely – Some carriers offer *69 as a callback service, allowing you to return the last No Caller ID call without exposing your number. However, this feature isn’t available on all networks.
• Report and Block Suspicious Calls – Use your phone’s settings to block No Caller ID calls or enable the call filtering provided by your carrier. Reporting these calls helps prevent further spam.
