What You Should Know About Caller ID

Before we go into disguising your phone number on an iPhone, let’s first define Caller ID. Caller ID is a telecommunications service that allows the recipient of a call to see the caller’s phone number or name before responding. By default, iPhones have the Caller ID feature activated, displaying your number to the person you’re calling.

However, there are times when you would like to keep your phone number secret, which is where the ability to hide your Caller ID comes in handy.

Why Block Your Number on iPhone Calls?

You may wish to disguise your phone number when making calls from your iPhone for a variety of reasons, including:

  • Protecting Your Privacy: In an age where personal information is freely available, masking your phone number can protect your privacy and keep your phone number from getting into the wrong hands.
  • Avoiding Unwanted Calls: By masking your phone number, you lessen the likelihood of receiving unsolicited calls from telemarketers and spammers, who frequently utilize exposed phone numbers.
  • Professional and Business Reasons: In a work context, you may wish to call clients or customers without giving your phone number, keeping your personal and professional lives separate.

Methods to Block Your Number on iPhone Calls

Apple recognizes the importance of privacy and offers many options for hiding your Caller ID:

1. Using the Settings app: The Settings app is the most often used method for hiding your phone number on an iPhone.

Follow these steps to accomplish this:

  • Step 1: Launch the iPhone Settings app.
  • Step 2: Scroll down to the “Phone” option.
  • Step 3: Hover over “Show My Caller ID.”
  • Step 4: Deactivate the toggle next to “Show My Caller ID.”

When you’ve finished these procedures, your phone number will be concealed for all incoming calls. However, bear in mind that if your carrier does not enable Caller ID concealing, this setting may not function.

2.*Using the temporary #31# prefix: If you simply wish to disguise your number for a single call, dial *#31# before dialing the recipient’s number.

The procedures are simple:

  • Step 1: On the dial pad, enter *#31#.
  • Step 2: As usual, dial the recipient’s phone number.
  • Step 3: Your phone number will be masked for this call only.

It’s crucial to remember that some carriers may not support this temporary concealing option, so check compatibility beforehand.

3. Using the Contacts app: You can also hide your phone number for particular contacts by changing their settings in the Contacts app.

To accomplish this:

  • Step 1: On your iPhone, launch the Contacts app.
  • Step 2: Locate the person you want to call using a disguised number.
  • Step 3: Select “Edit” in the upper-right corner.
  • Step 4: Scroll to the bottom and click “Add Phone.”
  • Step 5: Enter a fictitious or temporary phone number, or just enter a single character (for example, “x”) in the phone number box.
  • Step 6: Save the contact information.

When contacting this specific person, your phone number will not be visible.

4. Using a carrier code: Some carriers have their codes for activating or deactivating Caller ID. If the procedures described above do not work, you can call your carrier’s customer service or visit their website to find precise codes for activating or deactivating Caller ID.

Step-by-Step Guide to Block Your Number

Now that we’ve explored the many options for blocking your phone number, let’s go over the step-by-step approach for each method:

Method 1: Make use of the Settings app

Step 1: Open the Settings app

Locate the “Settings” app on your iPhone’s home screen. It is commonly represented by a gear symbol. Tap it to access the Settings menu.

Step 2: Locate the Phone option

Scroll down in the Settings menu and seek for the “Phone” option. It should be in the part where you can access all of your phone’s settings.

Step 3: Select the ‘Show My Caller ID’ option.

Locate the “Show My Caller ID” option while you’re in the “Phone” area. It’s usually found in the “Calls” or “Phone Calls” subsection.

Step 4: Enabling the ‘Show My Caller ID’ toggle

The toggle next to “Show My Caller ID” is switched on by default, which means your phone number is shown when you call. To hide your phone number, simply switch off the toggle. When the switch turns gray, you’ll know it’s turned off.

Step 5: Make a test call to verify

It’s a good idea to make a test call to a friend or family member after deactivating the “Show My Caller ID” option to confirm that your number is hidden. If you are successful, your phone number will not display on their screen when you call.

Method 2: Blocking Your Number for a Specific Call

If you simply want to mask your phone number for one call, use the temporary *#31# prefix:

Step 1: Dialing #31#

Before inputting the recipient’s phone number, open the phone app on your iPhone and dial *#31#. For example, if you wish to call (555) 123-4567, enter *#31#5551234567.

Step 2: Making the call

After entering the temporary prefix and the recipient’s phone number, simply hit the call button as you would for any other call. For this call, your phone number will be disguised.

Note: Please keep in mind that, while the temporary prefix works for many carriers, it may not work for all. Before utilizing this approach, ensure compatibility.

Troubleshooting Caller ID Hiding Issues

Even if you follow the procedures above, you may run into problems while attempting to mask your phone number on iPhone calls. Here are some examples of typical issues and their solutions:

  • Caller ID not hiding for all calls: If you’ve disabled the “Show My Caller ID” option in the Settings app but your number still appears on certain calls, check with your carrier to see if your plan allows Caller ID hiding.
  • Temporary prefix not working: If the *#31# prefix does not conceal your phone number, your carrier may not support this function. For alternatives, contact your carrier’s customer service.
  • Hidden ID not working for specific contacts: Check that you’ve added a temporary number or character to the contact’s information appropriately. Double-check that you’ve saved the changes after editing the contact.

Pros and Cons of Blocking Your Number

Hide your phone number has advantages and downsides, just like any other privacy measure:

Advantages of hiding your ID:

  • Enhanced Privacy: Hiding your phone number provides an additional degree of privacy and security against any misuse.
  • Avoiding unsolicited Calls: By concealing your phone number, you lessen the likelihood of receiving unsolicited calls from telemarketers and spammers.
  • Professionalism: Hiding your phone number for business or professional calls might establish a more official and discrete communication channel.

Disadvantages and potential drawbacks:

  • Limited Emergency Response: Hiding your phone number during an emergency may cause response times to be delayed or impair emergency services’ ability to locate you swiftly.
  • Call Screening: Some recipients may refuse calls from unknown or concealed numbers, causing communication difficulties.
  • Anonymity Concerns: Using a concealed number may arouse suspicions or lead to misinterpretations of your intentions in certain situations.


Finally, masking your phone number on iPhone calls may be a useful approach to safeguard your privacy, avoid unwanted calls, and manage your business relationships. You may simply control whether your phone number is revealed to others by using the Settings app, temporary prefixes, or individual contact settings.

However, keep in mind that disguising your phone number has restrictions, notably in emergencies and legal needs. Before utilizing this feature, always consider the context and potential consequences.

As technology advances, so do privacy problems and the means for dealing with them. Keep up with operating system upgrades for your iPhone and look for reputable privacy and security solutions.

By embracing privacy features and adopting safe communication practices, you can enjoy a more secure and confident experience when using your iPhone for calls and messaging.
