How to hide a phone number on Android: a complete guide with proven methods

Hiding a phone number when making calls is a pressing task for those who value privacy. In the digital age, when personal data becomes increasingly vulnerable, controlling its distribution has become an essential skill. On Androiddevices, there are several ways to hide your number from the recipient: from built-in operator functions to third-party applications.

It is important to understand that not all methods are equally effective. Some only work for outgoing calls within one country, others may be blocked by the operator or recipient. In this article we will examine 8 proven methodsincluding little-known technical techniques that will help you remain anonymous in most situations.

1. Built-in number hiding function in Android

The easiest way to hide a number is to use the built-in phone settings. Most modern Androiddevices (starting from version 6.0) support this function at the system level. Here's how to activate it:

Go to the application Phone, click on the three dots in the upper right corner and select Settings. Next, find the section Advanced settings or Call settings (the name may differ depending on the firmware). There will be an item Additional parameters or Caller IDwhere you can select the option Hide number.

• ✅ Works on most smartphones without additional applications
• ⚠️ Some operators may ignore this setting
• 🔄 Re-activation is required after resetting the settings

This method changes the setting CLIR (Calling Line Identification Restriction) in the operator's network. However some corporate numbers and emergency services will still see your real number regardless of this setting.

2. Using operator USSD commands

Each mobile operator provides USSD commands to manage services. To hide a number at the network level, you can use the following combinations:

Operator	Command for activation	Command for deactivation
MTS	*31# + number	#31# + number
Beeline	*31*number#	#31*number#
Megafon	*31# before the number	#31# before the number
Tele2	*31#number	#31#number

To permanently hide the number on MTS and Beeline you can send a USSD request *31# and press call. This will enable the feature for all outgoing calls. To return the number display, use #31#.

⚠️ Attention: Tariffs and conditions of USSD commands may change. Check the current combinations on the official website of your operator or through your personal account.

This method is more reliable than system settings, since hiding occurs at the operator’s network level. However, some international numbers may ignore this parameter.

3. Applications for hiding your number

If the built-in methods do not work, you can use specialized applications. They offer additional features, such as choosing a temporary number or recording conversations.

• 📱 Hushed — provides virtual numbers for calls and SMS (there is a free plan)
• 🔒 Burner — creates temporary numbers that can be changed on demand
• 🌍 TextNow — toll-free numbers for the USA and Canada, works via VoIP
• 📞 CoverMe — encrypts calls and offers hidden numbers

Most of these applications use technology VoIP (voice over IP), which allows you to bypass the restrictions of mobile operators. However, the quality of communication may depend on the speed of the Internet.

Install the application from the official store|Check reviews and ratings|Set up call permissions|Test the quality of communication|Check out the tariffs (if applicable)-->

When using such applications for the first time, verification may be required via email or another phone. Some services (for example, Burner) offer paid subscriptions for advanced features.

4. Hiding a number via Google Voice

For users from the USA and some other countries, a service is available Google Voicethat allows you to call through a virtual number. Here's how to use it:

1. Install the application Google Voice from Play Market
2. Register and select a toll-free number
3. In your account settings, activate the option Anonymous mode
4. Make calls through the app - the recipient will see a virtual number

The advantage of this method is that Google Voice is integrated with other Google services and supports SMS transmission. However, the service is not officially available in all countries.

How to bypass regional restrictions of Google Voice?

To register in unSupported regions, you can use a VPN with access to the USA. After registration, the service will work without a VPN, but an American number is required for verification (you can use temporary SMS services).

5. Using SIP telephony

For advanced users, it is possible to configure SIPtelephony. This method requires more time to set up and provides maximum anonymity.

Popular SIP providers that support anonymous calls:

• 📡 VoIP.ms - flexible settings with the ability to hide Caller ID
• 🌐 Callcentric - toll-free numbers for the USA with an anonymity option
• 🔌 Flowroute - paid service with a high communication quality

To use SIP telephony on Android you will need to:

1. Register with a provider and get a SIP account
2. Install a softphone application (for example, Zoiper or Linphone)
3. Configure credentials in the application
4. In the call parameters, specify the option to hide the number

⚠️ Attention: Some SIP providers may block accounts if fraudulent activity is suspected. Use this method only for legitimate purposes.

This method is suitable for those who often call abroad or need additional ones. functions such as call recording or call forwarding.

6. Hardware solutions: second SIM or eSIM

One of the most reliable ways to remain anonymous is to use a separate SIM card or eSIM specifically for calls where you want to hide the main number.

Advantages of this method:

• 🔄 Complete isolation from the main number
• 📱 Ability to use cheap tariffs without monthly fees
• 🛡️ No dependence on applications and Internet connection

For maximum anonymity you can:

• Buy a SIM card for cash without presenting documents (in some countries)
• Use virtual operators (MVNO) with minimal verification
• Activate eSIM through online services without visiting a salon

The disadvantage of this method is the need to have a second phone or device that supports two SIM cards. Also, some operators may require passport data even for prepaid tariffs.

7. Features of hiding a number in instant messengers

Many modern instant messengers allow you to call without displaying your main phone number. Let's consider the most popular options:

Messenger	Method of hiding the number	Restrictions
WhatsApp	Using a business account with a different number	A second number is required for registration
Telegram	Calls through a username without reference to a number	The recipient must be in your contacts
Signal	Registration through a virtual number	Requires confirmation of the number upon registration
Viber	Hide the number in privacy settings	Works only for contacts from the phone book

In Telegram you can do without a phone number altogether if you use the function @username for calls. However, you will still need a SIM card for initial registration.

8. Legal aspects and restrictions

Before hiding your number, it is important to understand the legal consequences of this action. In most countries, hiding a number in itself is not a violation, but its use for fraudulent activities is punishable by law.

Main restrictions:

• 🚨 Emergency services (112, 911, etc.) always see the real number
• 🏛️ Banks and government agencies can block calls from hidden numbers
• 📵 Some countries (for example, India) prohibit hiding numbers at the legislative level
• 🔍 Operators can provide your number at the request of law enforcement agencies

In Russia, since 2026, rules have been in force obliging operators to disclose numbers if fraud is suspected. This means that even when using hiding methods, your number can be identified in the event of a complaint from the recipient.

If you use number hiding for business purposes (for example, a call center), make sure that this does not violate consumer protection laws in your country.

FAQ: Frequently asked questions about hiding a number on Android

Is it possible to hide a number when call to a landline phone?

Yes, most methods (USSD commands, applications, SIP) also work for calls to landline numbers. However, some landline PBXs may ignore the request to hide or display the number as “Unidentified”.

Why does the recipient still see my number, despite the settings?

This can happen for several reasons: 1) Your operator does not support hiding for international calls; 2) The recipient uses special software to determine the numbers; 3) You call an emergency number or a corporate PBX that ignores CLIR settings. Try the alternative methods from this article.

How to hide a number when sending an SMS?

Hiding a number when sending an SMS is more difficult than when making calls. Most operators do not support this feature at the network level. Alternative options: 1) Use instant messengers (Telegram, Signal); 2) Send SMS through applications like TextNow; 3) Use email-to-SMS gateways (for example, send a message to number@operator.ru).

Will hiding a number work in roaming?

In roaming, the effectiveness of hiding depends on the agreement between your operator and the local provider. Often when roaming, hiding is disabled automatically. Before traveling, check the conditions with your operator or use alternative methods (applications, SIP, second SIM).

Is it possible to permanently delete the history of calls with a hidden number?

Yes, but it depends on the hiding method: 1) If system settings or USSD were used, the history remains in the call log (delete manually); 2) When using applications, the history is stored in the application itself (can be cleared in its settings); 3) For SIP and VoIP - check the logs on the provider's server. Complete removal of traces is only possible with a combination of several methods.
