A private call is useful when you want to withhold your number for a specific conversation, but the setting is easy to misunderstand. A one-call prefix, a phone setting, and a carrier-level block can all affect what the recipient sees, while none of them promises complete anonymity. Start by deciding whether you need to hide one call or every call.
Choose One-Call or Default Caller ID Blocking
Start with what you actually want. The right method depends on whether you are hiding one call or hiding your number by default.
| What you want | Where to start | How long it applies |
|---|---|---|
| Hide your number for one ordinary phone call | Use the carrier's supported per-call prefix, such as *67 on the US services below |
That call |
| Hide your number by default on an iPhone | Check Show My Caller ID | Until changed, where the carrier supports it |
| Hide your number by default on Android | Check the supported Phone app setting for your device and carrier | Until changed, where supported |
| Manage blocking through your carrier | Use its account controls or contact support | Depends on the service |
These are not four independent methods. A device setting and a carrier setting can control the same outgoing feature. Verizon's temporary block flow applies only to the call you place with it, while its default blocking controls are limited to the Account Owner or Account Manager.
How to Call Private With *67
Verizon mobile, AT&T Wireless, and T-Mobile document *67 for blocking Caller ID on a single call. Your carrier is the company that provides or bills your phone service. Caller ID is the name and number that appear on the recipient's screen.
- Open the Phone app's keypad.
- Enter
*67, followed by the destination number in the format your carrier requires. - Press Call after entering the complete dialing sequence.
| Service checked | Documented dialing sequence |
|---|---|
| Verizon mobile | *67, then the number including its area code |
| AT&T Wireless | *67, then the 10-digit number |
| T-Mobile | *67, then the destination number, as its step-by-step guide describes |
Enter the prefix and the destination number as one complete dialing sequence. Do not call *67 by itself and then place a separate call.
Enter the prefix again for every call you want to hide. Do not assume a redial entry will preserve it. The recipient may see Private, Anonymous, or a similar label. Verizon says its Caller ID Blocking does not apply to 800 numbers or 911, and a hidden number does not guarantee that the call will be accepted.
On a traditional home phone, the sequence differs. Verizon's home-phone instructions say to press *67 at the dial tone, wait for the confirmation and dial tones, and then dial the number. The one-call block turns off after that call. Other landline users should check with their provider.
How to Hide Caller ID by Default
A default setting saves you from entering a prefix on every call, but it does not remove destination-specific exceptions. Emergency and toll-free numbers can still receive your number, and some recipients may reject private calls.
On iPhone
Use this setting when you want your iPhone to request Caller ID blocking by default. Apple documents the path in Apple's Phone settings guide:
- Open Settings.
- Tap Apps, then Phone.
- Tap Show My Caller ID.
- Turn it off.
When the setting is off, Apple says the recipient won't see your phone number. If the switch is dimmed or missing, Apple's guidance is to contact your carrier. A carrier can control whether the option is available.
On Samsung Galaxy and Other Android Phones
Android has no single verified menu path across every phone and carrier. The steps below are the path Samsung documents for Galaxy devices in Samsung's Galaxy walkthrough for hiding your caller ID:
- Open Phone.
- Open More options (three dots), then Settings.
- Select Supplementary services.
- Select Show your caller ID.
- Choose Never.
This path comes from Samsung's UK support page, so it is an example for Galaxy devices, not a guarantee for every US Galaxy phone, Android version, or carrier. Available menus depend on the device, carrier, and country. If the path is absent, follow the instructions for your exact device and carrier.
In Google's Phone app, See caller ID & spam manages caller identification and spam features. Google states that it does not control whether your number shows when you make calls.
When the Carrier Controls the Setting
Some carriers manage default blocking on their side. Verizon documents default Caller ID Blocking through My Verizon, and only the Account Owner or Account Manager can change it. AT&T says to contact support if your device cannot manage the setting. T-Mobile points readers to its Device Support pages for default blocking.
How to Show Your Number Again
Undoing a private call depends on what you changed in the first place.
- Used
*67for one call: place the next call without that prefix, unless a separate default block is active on the line. - Changed the iPhone setting: open Settings, tap Apps, tap Phone, tap Show My Caller ID, and turn it back on.
- Selected Samsung's Never option: choose Always in the same Caller ID menu. The Network default option follows the network's own setting, so it does not inherently mean show or hide.
- Enabled carrier-level blocking: change that carrier setting or ask its support team to remove it.
If Verizon default blocking is active, Verizon lists *82 as the option to show your number for one call. Enter *82, then the number, and tap Call. This is a Verizon-specific, per-call option, not a universal reset. Displaying your number is your own choice about what you send, not a way around someone else's contact restrictions.
Why Calling Private Might Not Work
When a private call does not behave as expected, the observation and the cause are usually two different things. The table below pairs what you notice with what to check and what to do next.
| What you notice | What to check | What to do next |
|---|---|---|
| Your number still appears | The full dialing sequence, your service's instructions, and the type of number called | Check the carrier's format; use the verification checklist below |
| The iPhone switch is missing or grayed out | Whether the carrier can manage the feature on your line | Contact the carrier; do not assume a device reset will change a carrier-controlled option |
| Your Android menus do not match | The exact device, Phone app, country, and carrier | Use the official guide for your model; Samsung notes that some carriers and countries do not allow number hiding |
| You switched off Google's caller ID and spam option | Whether you changed identification and spam features instead of outgoing Caller ID display | Use an outgoing setting or the carrier's per-call method; Google's setting does not control whether your number shows when you make calls |
| The call is rejected or does not connect | Whether the destination accepts private calls | Respect the recipient's preferences and use an agreed contact method |
The number is still hidden when you omit *67 |
Whether a device or carrier default block remains active | Review the setting you enabled and restore display if you choose |
What a Private Call Does Not Hide
Hiding ordinary Caller ID is a display-privacy feature. It does not make you anonymous or promise that the call cannot be identified later. Verizon's home-phone guidance distinguishes withheld Caller ID from spoofing, where a caller displays false information instead of withholding the number.
The destination limits above still apply, and a recipient who sees no number may have no easy way to call you back. If you want to understand what the other person sees when a number is withheld, read what a restricted call means.
Check Your Setup Before You Call
Before you rely on a private call for anything that matters, run through a short check.
- Confirm whether you changed a single call or the default setting for every call.
- Check that you are dialing the full number in the format your carrier expects, since a temporary block only applies when the code and the number are entered together.
- Call an ordinary phone you control, or ask someone who has agreed to help, and see what the recipient's screen shows.
- If you want your number visible again, undo the setting and repeat the check.
- Treat the result as confirmation of that one call, not of every destination, app, or network.
