Effective Methods To Call Private And Keep Your Number Hidden On Any Phone

In an age where privacy is increasingly fragile, knowing how to make a phone call without revealing your number can be essential. Whether you're contacting a business, reaching out to someone cautiously, or protecting yourself from unwanted callbacks, maintaining caller anonymity is a practical skill. Fortunately, modern phones—regardless of brand or operating system—offer multiple ways to hide your identity during outgoing calls. From built-in dialer settings to third-party apps and carrier services, the tools are accessible and often free.

This guide explores proven, reliable methods to call privately across iOS, Android, and traditional landlines. You’ll learn when to use each method, their limitations, and how to ensure your number stays concealed every time.

Understanding Caller ID and Privacy

Caller ID is a standard telecommunication service that transmits the caller’s phone number (and sometimes name) to the recipient’s device. While useful for identifying incoming calls, it also means your number is automatically shared when you make a call—unless you take steps to block it.

Blocking your number doesn’t require advanced technical knowledge. Most mobile carriers support suppression codes, settings toggles, or network-level privacy features. However, effectiveness varies depending on the recipient’s carrier, country regulations, and whether they use call-blocking software.

“While no method guarantees 100% anonymity, combining suppression codes with app-based calling significantly reduces the risk of exposure.” — David Lin, Telecommunications Security Analyst

Method 1: Use Built-In Phone Settings

Both iPhone and Android devices allow users to disable caller ID globally through system settings. This method ensures all outgoing calls are private unless manually overridden.

iOS (iPhone)

Navigate to Settings > Phone > Show My Caller ID. Toggle this setting off. Once disabled, your number will appear as “Private,” “Blocked,” or “Unknown” on the recipient’s phone.

Android (varies by brand)

Open the Phone app > Settings > Supplementary Services > Show My Number. Select “Hide Number” to apply globally. Note: Path may differ slightly between Samsung, Google Pixel, and other manufacturers.

Tip: Test the setting by calling your own voicemail or a trusted contact before relying on it in sensitive situations.

⚠️ Limitation: This setting applies to all calls. If you only want to hide your number occasionally, per-call blocking (see next section) is more flexible.

Method 2: Per-Call Blocking Using Dial Codes

If you prefer selective privacy, temporary suppression codes let you hide your number on a call-by-call basis. These work on most carriers in North America and many international networks.

North American Format (US & Canada)

Before dialing the number, enter *67, then the full 10-digit phone number.

Example: *67 555-123-4567

The recipient will see “Private Caller,” “Blocked,” or “No Caller ID.”

UK and Europe

Use 141 before the number:

Example: 141 020 7946 0000

Australia

Dial 1831 before the number to hide your ID temporarily.

These codes must be entered each time. They do not affect future calls unless reapplied.

Tip: Save frequently called private numbers with the code already prefixed in your contacts (e.g., *67 555-123-4567).

Method 3: Carrier-Level Caller ID Blocking

For permanent privacy, request your carrier to suppress your number by default. This service is often free and applies to all outbound calls.

Contact customer service or log into your account online to enable “Anonymous Call Rejection” or “Caller ID Blocking.” Once activated:

• All outgoing calls will display as private.
• You can unblock temporarily using *82 (in the US) before dialing.
• Emergency services (911) will still receive your number for safety.

This method is ideal for professionals who regularly need privacy, such as investigators, counselors, or journalists.

Method 4: Third-Party Calling Apps

Apps like Google Voice, Burner, and TextNow provide alternative phone numbers for calling and texting. Since these numbers aren't tied directly to your personal line, they offer enhanced privacy.

Google Voice (US Only)

Sign up at voice.google.com using a Gmail account. Choose a local number and use the Google Voice app to make calls. Recipients see your Google Voice number—not your real one.

Burner Apps

Applications like Burner or Hushed create disposable phone numbers. Ideal for short-term needs like online dating, classified ads, or temporary business use.

App	Privacy Level	Cost	Best For
Google Voice	High (separate number)	Free	Long-term private calling
Burner	Very High (disposable)	Paid (subscription)	Temporary anonymity
TextNow	Moderate	Free with ads / Paid ad-free	Casual private calls

“Using a secondary number via apps adds a layer of separation between your identity and communication—critical in today’s data-driven world.” — Lila Chen, Digital Privacy Consultant

Method 5: Landline and VoIP Solutions

Traditional landlines can also hide caller ID using the same *67 prefix. However, many businesses and homes now use VoIP (Voice over IP) services like Vonage, Ooma, or Comcast Digital Voice.

VoIP platforms typically include privacy settings within their web dashboards. Log in to your account and look for options like:

• “Block Outgoing Caller ID”
• “Anonymous Call Settings”
• “Privacy Mode”

Some VoIP systems allow rule-based blocking—hide your number only when calling specific area codes or numbers.

Real-World Scenario: A Journalist Protecting a Source

Sophia, an investigative reporter, needed to contact a whistleblower without exposing her personal cell number. She used Google Voice to create a dedicated reporting line. By routing all communications through this number, she maintained professional boundaries and protected both her identity and her source’s security. When calling from her mobile, the recipient saw only the Google Voice number, which could be deactivated if compromised.

This approach ensured continuity, trust, and operational safety—proving that strategic number management is vital in sensitive roles.

Step-by-Step Guide: How to Make Your First Private Call

1. Determine your goal: Do you want temporary privacy or long-term anonymity?
2. Choose a method: For one-off calls, use *67. For ongoing needs, set up Google Voice or adjust phone settings.
3. Test the method: Call a friend or your voicemail to confirm your number appears as “Private” or “Blocked.”
4. Adjust settings if needed: If the code fails, check with your carrier for regional variations.
5. Document your process: Save preferred methods in notes for future reference.

Common Mistakes That Expose Your Number

• Assuming *67 works everywhere: Some countries and carriers don’t support it.
• Forgetting to re-enable caller ID: After global blocking, important calls (e.g., customer service) may reject blocked numbers.
• Using untrusted calling apps: Some free apps sell user data despite promising privacy.
• Not updating app permissions: Ensure calling apps have microphone access but limit unnecessary data permissions.

FAQ

Will *67 work if the recipient has call-blocking enabled?

It depends. Some spam filters automatically reject calls from private numbers. The recipient may not receive the call at all, or it may go straight to voicemail labeled as “Spam Risk.”

Can I hide my number when sending text messages?

Standard SMS cannot be hidden using *67. However, messaging apps like Signal, WhatsApp, or Google Voice allow number masking since messages route through the internet, not the carrier network.

Are there legal restrictions on hiding my number?

In most countries, blocking your caller ID is legal. However, using it to harass, scam, or defraud others is a criminal offense. Always use privacy tools ethically.

Checklist: Ensuring Your Number Stays Hidden
