How to Make a Private Call? Hide Your Number on iPhone & Android

Written by Aaron Boatin | August 15, 2025

You need to call someone but don't want them to see your number. Maybe you're calling about a job listing and don't want random callbacks. Or you're reaching out to someone you don't know well. Whatever the reason, hiding your caller ID is easier than you think. Here's how do you private call using your iPhone, Android, or landline—with clear steps and honest warnings about what works and what doesn't.

Quick Answer (One-Minute How-To)

Making one private call only:

  • Dial star 67 + number to hide your caller ID for one call (US/Canada)
  • Example: *67-555-123-4567

To hide your number on every call:

  • iPhone: Settings → Phone → Show My Caller ID → Off (if your carrier allows it)
  • Android: Phone app → Caller ID settings → Hide number (wording varies)

To show your number for one call when it's normally hidden:

  • Dial star 82 + number
  • Example: *82-555-123-4567

Are there any limits to this? Yes. It won't work on toll-free numbers or 911. Some people block hidden calls. Your carrier might override these settings. Now let's look at the specifics.

Method 1: Make a Private Call for Just One Call

Use *67 (US/Canada)

Star 67 is the easiest way to block caller id for a single call. It works on almost any phone—iPhone, Android, or landline. When you use star 67, the person you're calling sees "Private," "Unknown," or "No Caller ID" instead of your number.

Here's how to call private using star 67:

  1. Open your phone app
  2. Type *67 before the phone number
  3. Include the area code
  4. Press call

Example: To call 555-123-4567 privately, dial *67-555-123-4567

Does star 67 still work? Yes, but it has limits. It won't hide your number from toll-free numbers (800, 888, 877). Emergency services like 911 will always see your real number. Some businesses and people automatically block calls from hidden numbers.

UK and Other Regions

If you're outside the US and Canada, star 67 probably won't work. In the UK, use the UK 141 code instead. Dial 141 + the phone number to make an anonymous call.

For other countries, contact your phone carrier to learn the local code for blocking caller ID.

Method 2: Hide Your Number on Every Call

Sometimes you want to block caller id permanently instead of dialing star 67 every time. Both iPhone and Android let you hide caller ID on iPhone and hide caller ID on Android through your settings.

Steps for iPhone

To hide your number on all outgoing calls:

  1. Open Settings
  2. Tap Phone
  3. Tap Show My Caller ID
  4. Turn off Show My Caller ID

Now every call you make will appear as "No Caller ID" to the person you're calling.

Important note: Some carriers remove this toggle from iPhone settings. If you don't see the "Show My Caller ID" option, your carrier controls this feature. You'll need to contact them directly to enable permanent caller ID blocking.

Steps for Android

Android phones handle caller ID settings differently depending on your phone manufacturer and carrier. Here's the general path:

  1. Open your Phone app
  2. Look for Settings or three dots menu
  3. Find "Caller ID" or "Additional settings"
  4. Select "Hide number" or "Don't show number"

The exact wording varies by phone. Samsung phones might say "Show caller ID." Google Pixel phones often put this under "Calls" then "Additional settings." If you can't find these Caller ID settings, search for "Caller ID" in your phone's main Settings app.

You Should Ask Your Carrier for Caller ID Blocking

All major phone carriers can apply caller ID blocking at your account level. Call customer service and ask for "caller ID blocking" or "anonymous calling."

This works even when your phone doesn't have the setting built-in.

The downside? You might pay a monthly fee (usually $2-5). The upside? It works reliably and can't be accidentally turned off.

Method 3: Use a Second Number (Best for Ongoing Privacy)

Sometimes blocking caller ID isn't enough. You might want a completely separate number for certain activities. A second phone number app gives you more control and flexibility than star 67.

Popular options include getting a Google Voice number (free) or using a burner number app like Burner or Hushed (paid). These apps give you a real phone number that forwards to your main phone.

Benefits of a second phone number:

  • Works for both calls and text messages
  • You can give this number out freely
  • Easy to change or delete if it gets too much spam
  • Works internationally

The setup is usually quick. Download the app, pick your number, and start using it right away. When people call your second number, your phone rings but shows the second number as the caller.

Unblocking for One Call

Let's say you've set your phone to hide caller ID on every call, but now you need to show your number for one specific call. Maybe you're calling for a delivery or need a callback from customer service.

Use star 82 to show your caller ID for just that call. Here's how to unblock caller id for one call:

  1. Dial *82 before the phone number
  2. Include the area code
  3. Press call

Example: *82-555-123-4567

This temporarily overrides your permanent caller ID blocking setting. Your next call will go back to being private.

What Private Calling Can't Do

Before you start making private calls, understand the limits:

Toll-free and emergency numbers always see your real number. This includes 800, 888, and 877 numbers, plus 911 and other emergency services. This is built into the phone system for safety and business reasons.

Some people and businesses automatically block hidden calls. They won't even ring – the call just fails or goes straight to a "this number doesn't accept private calls" message.

Text messages don't work with star 67. If you want to send anonymous texts, you need a second phone number app or Google Voice number.

Your carrier might override your settings. Some phone companies don't allow permanent caller ID blocking or might charge extra fees.

Do Some Quick Troubleshooting

iPhone toggle missing? 

This usually means your carrier controls the caller ID setting. Contact them to enable it on your account.

Android menu looks different? 

Phone manufacturers change these menus frequently. Try searching for "Caller ID" in your main Settings app, or check if your carrier has their own phone app with these controls.

Want to test your setup? 

Call a friend or family member to confirm they see "Private" or "Unknown" instead of your number. You can also call your own voicemail from another phone to test.

FAQs

Does star 67 still work? 

Yes, star 67 works on most US and Canadian phone networks. It won't work for toll-free numbers, 911, or people who block private calls.

Is making a private call legal? 

Generally yes for normal personal use. Don't use it to harass people or commit fraud – that's illegal regardless of whether you hide your number.

Can I call from a private number on landline? 

Most landline carriers support star 67, but some use different codes. Ask your phone company about their caller ID blocking options.

Will my number show to 911? 

Yes, emergency services always see your real number and location, even when you're using caller ID blocking. This is a safety feature.

Why did my private call fail? 

The person you're calling might block all private calls. Try calling with star 82 to show your number, or leave a voicemail explaining who you are.

How do I know if someone is calling me privately? 

Your phone will show "Private," "Unknown," "No Caller ID," or similar instead of a phone number.

Can I make my texts private too? 

No, star 67 doesn't work for text messages. You need a second phone number app like Google Voice or a burner number service.

Pick the Right Method (and Be Respectful!)

Now you know exactly how do you private call using different methods. Star 67 works great for one-off calls when you want quick privacy. Permanent caller ID blocking through your phone settings or carrier works better if you want to hide your number most of the time. A second phone number gives you the most control and works for both calls and texts.

Remember that private calling is a tool for legitimate privacy, not for bothering people. If someone doesn't answer your private call, respect their choice. Many people don't answer unknown numbers as a safety precaution. When in doubt, leave a polite voicemail explaining who you are and why you're calling.

Choose the method that fits your needs, test it with a friend first, and use it responsibly.

Your privacy matters, but so does being a good phone citizen.
