How to make calls with a hidden number on Android and iPhone

Want to make calls without your number being visible to the recipient? Hiding your number can be a practical solution to protect your privacy, avoid unwanted calls, or simply maintain anonymity in certain situations. Below, we clearly explain how to make calls with a hidden number on both Android and iPhone devices.

Why calling with a hidden number can be useful

Hiding your phone number when making a call has several advantages, including:

  • Privacy: You don't reveal your number to people you don't know or with whom you prefer not to share it.
  • Avoid callbacks: If you don't want them to call you back, hiding your number is an option.
  • Security: In sensitive situations, such as calls to unknown services or contacts, protecting your identity can be important.

However, it is also essential to use this feature responsibly, as some recipients may not answer calls from hidden or anonymous numbers.

How to make calls with a hidden number on Android step by step

Android devices have built-in options to hide your number on outgoing calls. The process may vary slightly depending on the brand and system version, but it generally follows these steps:

1. Access the phone application

Open the app you use to make calls (usually called "Phone").

2. Go to 'Settings' or 'Adjustments'

Look for the settings menu within the app. On many Android devices, this is accessed by tapping the three vertical dots or the gear icon in the upper right corner.

3. Select 'Call settings' or 'Call configuration'

Within this menu, you will find options related to calls.

4. Look for the 'Show my caller ID' option or something similar

Here you can choose how your number is displayed when you call:

  • Show number
  • Hide number
  • Network default

5. Select 'Hide number'

By selecting this option, your number will not appear on the calls you make.

6. Make the call

Dial the number you wish to call and your number will appear as private or unknown to the recipient.

Alternative: Use a code to hide the number

If you don't want to change the settings permanently, you can dial a code before the number to hide your caller ID only on that call. In most countries, the code is:

  • #31# + number (for example, #31#123456789)

This method is quick and does not require changing settings.

How to make calls with a hidden number on iPhone step by step

On iPhone, hiding your number is also easy and can be done directly from the device settings.

1. Open 'Settings'

Look for the settings icon on your home screen.

2. Select 'Phone'

In the settings menu, tap the option that says "Phone".

3. Enter 'Show Caller ID'

Here you'll see a switch that controls whether your number is displayed when making calls.

4. Turn off 'Show Caller ID'

By turning off this option, your number will be hidden from outgoing calls.

5. Make the call

Now, when you call, the recipient will see "Hidden number" or "Unknown".

Note on operators and restrictions

Some carriers don't allow you to hide your number using this feature or may require special activation. In that case, you can use the code:

  • #31# + number

To hide the number on that specific call.

Tips and considerations when calling with a hidden number

  • Verify that the code or setting works: Some countries or operators block calls with hidden numbers.
  • Respect the person you call: Many people don't answer blocked numbers for safety reasons.
  • Use this option only when necessary: ​​Avoid abusing anonymity to protect your reputation.
  • Check the settings before calling: In important cases, confirm that your number is hidden if that is what you want.

What to do if you can't hide your number?

If your number still appears after following the steps, it could be because:

  • Telephone operator restrictions.
  • Settings locked on device.
  • Use of apps or services that display the number.

In these cases, contact your operator to request service activation or explore alternative options.
