Hide Phone Number on Android (Caller ID Setting)

To hide your number on Android, open your Phone app’s caller-ID settings and choose “Hide number” or “Never,” if your carrier allows it. The exact menu depends on your phone and network. For one call, use your carrier’s confirmed prefix, such as *67 in North America. This hides caller-ID display, not your identity from your carrier.

Caller-ID suppression can be useful when you want more privacy for a particular call or want your number hidden by default. On a premium Android phone, though, the control is not always where you expect it: the Phone app provides the menu, while your carrier and the receiving service affect whether the choice works.

I recommend checking the active SIM and testing the setting before relying on it. The instructions below cover Google Phone and Samsung Galaxy phones, one-time blocking, and common reasons the option may be missing or ignored.

Confirm Carrier and Device Support

Caller-ID blocking is a network feature that your Android phone can request. Android does not enforce one universal menu or guarantee that every carrier will honor the request. Before changing settings, identify which SIM and calling app you use, then check whether your carrier supports outgoing caller-ID restriction on that line.

Start with these checks:

• Note your carrier and the SIM used for outgoing calls. On a dual-SIM phone, each line may have different settings or support.
• Identify the Phone app you use. Google Phone and Samsung Phone have different menu paths.
• Check whether your carrier supports caller-ID blocking. Its website, support team, or account settings may confirm this.

If your phone has two SIMs, make a test call with the line you want to configure. A setting for one SIM may not affect calls placed through the other. If the carrier controls the feature, an option in Android may be absent, unavailable, or reset after a network or account change.

The key first step is to confirm support for the correct line. If you cannot find a clear answer, ask your carrier whether it can enable outgoing caller-ID restriction for that specific number.

Locate Caller-ID Controls

Caller-ID controls are usually part of the Phone app’s calling or supplementary-service settings. The menu names can vary by Android version, manufacturer, and carrier. Look for a setting called “Caller ID,” “Show your caller ID,” or a similar phrase, and make sure you are changing the active SIM rather than another line.

Google Phone app

In Google Phone, try this path:

1. Open Phone.
2. Tap the three-dot menu, then Settings.
3. Tap Calling accounts.
4. Select the SIM or carrier account used for calls.
5. Tap Additional settings.
6. Tap Caller ID, then choose Hide number.

Some versions may use slightly different labels or put the option elsewhere. If you do not see Calling accounts, check that you are using the Google Phone app and that the selected SIM is active. Your carrier may also restrict access to this control.

Samsung Galaxy Phone app

On many Samsung Galaxy phones, try:

1. Open Phone.
2. Tap the three-dot menu, then Settings.
3. Tap Supplementary services.
4. Tap Show your caller ID.
5. Choose Never.

The option may be missing or controlled by the carrier. If so, changing unrelated settings will not usually solve the problem; contact the carrier and ask about caller-ID blocking for your line.

“Never” generally requests that your number not be shown for outgoing calls. “Network default” returns control to the carrier’s usual setting, while “Show number” requests that your number be displayed. The exact choices can differ, so check the wording shown on your phone.

Apply Persistent or Per-Call Suppression

Persistent suppression changes the default caller-ID request for supported outgoing voice calls from the selected line. Per-call suppression applies only to one call, where the carrier supports a prefix. Choose the one that fits your need, and record the original setting so you can restore it later.

Hide your number by default

If the setting is available, choose Hide number in Google Phone or Never in Samsung Phone. This asks the network to suppress caller-ID presentation on supported calls. It does not create an anonymous connection, and the phone may show the choice even if the carrier does not support it.

To restore normal caller-ID display, return to the same menu and select Network default or Show number, depending on the options provided. If you do not see either choice, ask your carrier how to remove the restriction.

Hide your number for one call

In North America, many carriers support dialing *67 before the phone number for a single call. For example, enter *67 followed by the full number, then place the call. Confirm the prefix with your carrier before relying on it: codes differ by country and network, and a prefix that works on one line may not work on another.

A per-call prefix is often a better choice when you only need to withhold your number once. It avoids changing the default for later calls. Do not assume a prefix works just because the call connects; verify what the recipient sees.

Need	Method to try	Scope	What to check
Hide caller ID on most supported calls	Choose Hide number or Never	Ongoing until changed	Carrier support and correct SIM
Hide caller ID for one call	Use a carrier-confirmed prefix, such as *67 in North America	One call	Local code and recipient display
Restore usual display	Choose Network default or Show number	Ongoing	Confirm the setting saved

Verify Results and Understand Limitations

A successful test should show a label such as “Private” or “Unknown” instead of your number on the receiving phone. The label can vary by device and network. Test with a person who agrees to help, and remember that a blocked-call label confirms only what appears to that recipient, not that the call is anonymous.

Use this short check:

1. Place a test call to a consenting contact whose phone displays caller ID.
2. Ask what appeared on the screen.
3. If your number still showed, confirm you used the right SIM and recheck the setting.
4. If the option is missing or the test fails, contact your carrier.
5. Restore Network default or Show number when you want normal display again.

Caller-ID suppression is for supported voice calls. It does not hide your number on SMS or RCS messages. It also may not apply to emergency calls or toll-free numbers. A recipient’s carrier, phone system, or call-screening service may handle blocked calls differently, including rejecting them or asking the caller to identify themselves.

Most important, hiding the number from the recipient’s caller-ID display does not hide it from your carrier. The carrier can associate calls with your account and may keep call records under its policies and applicable rules. Do not treat this setting as a way to conceal identity from a network, emergency service, or lawful process.

Troubleshoot Missing or Ineffective Settings

A missing menu or a test that still displays your number usually points to carrier control, a line-selection issue, or a setting that did not apply. Work through those checks before installing an app or changing network details. Caller-ID display depends on carrier support, so an app cannot reliably override the carrier’s policy.

If the option is missing

Confirm that the correct SIM is active and selected in the Phone app. Check the carrier’s support information or contact its support team. Ask specifically whether outgoing caller-ID restriction is available and whether it must be enabled on your account.

If your number still appears

Check that the change was saved, then test a call from the intended SIM. If the menu shows the correct choice but your number still appears, ask the carrier to verify provisioning for that line. A per-call prefix may be an alternative, but only if the carrier confirms the correct code.

Avoid apps that promise to hide your number and avoid changing APN settings or unrelated permissions for this purpose. Those steps do not control the carrier’s caller-ID policy. Keep the fix focused: confirm the line, the Phone app setting, and carrier support.

Common Questions

These answers cover the most common questions about hiding caller ID on Android. The central distinction is between suppressing the number shown to a recipient and concealing the caller’s identity from the network. The first may be supported by a carrier setting; the second is not what caller-ID blocking does.

How do I hide my number on an Android phone?
Open the Phone app’s settings, find caller-ID controls for the calling SIM, and choose Hide number or Never if available. Menu names depend on the phone and carrier.

Where is caller ID in Google Phone?
Try Phone → three-dot menu → Settings → Calling accounts → select SIM → Additional settings → Caller ID → Hide number. Some carriers or Android versions use different menus or do not show the option.

How do I hide my number on a Samsung Galaxy?
Try Phone → three-dot menu → Settings → Supplementary services → Show your caller ID → Never. The option may be missing or controlled by your carrier.

Does *67 work on Android?
The prefix is not an Android feature. Many North American carriers support *67 before a number for one call, but codes and support vary. Confirm the correct prefix with your carrier.

Will the other person see “Private” or “Unknown”?
They may see “Private,” “Unknown,” or another blocked-caller label. The exact display depends on the receiving phone, carrier, and call-handling service.

Does hiding caller ID make me anonymous?
No. It suppresses caller-ID presentation where supported, but your carrier can still associate calls with your account. It does not guarantee anonymity from networks or recipient-side systems.

Does caller-ID blocking hide my number from texts?
No. The setting applies to supported voice calls, not SMS or RCS messages. Messages may display your number under the messaging service’s normal rules.

Why can’t I find the caller-ID setting?
The carrier may control the feature, or the app may use a different menu. Check the correct SIM and contact your carrier to ask whether it supports blocking on your line.

Can emergency or toll-free calls still identify me?
Caller-ID suppression may not apply to emergency or toll-free calls. Do not rely on it to prevent identification or call handling by those services.

How do I show my number again?
Return to the same caller-ID menu and choose Network default or Show number. If neither appears, ask your carrier to remove the restriction.

For a reliable result, check carrier support, set the option on the correct SIM, and confirm it with a test call. Use a carrier-approved per-call prefix when you only need to suppress caller ID once.
