How to Call No Caller ID on iPhone & Android (2026 Guide)
In the UK, you can usually dial 141 before the phone number to hide your number for one call. You can also change your caller ID settings on supported phones.
If you’re trying to call back someone who called you with No Caller ID, that is different. Your phone normally does not receive the caller’s number, so there is no number available to dial directly.
What Does “No Caller ID” Mean?
When your phone shows “No Caller ID,” it generally means the caller’s number was withheld before the call reached your phone.
You may also see labels such as “Private Number,” “Restricted,” or “Withheld.” The exact wording depends on the phone and network.
How to Call With No Caller ID?
If you want to make your own number appear as private or withheld, you have several options.
The easiest method depends on your country and carrier.
Method 1: Use a Caller ID Blocking Code
In the UK, dial 141 before the phone number you want to call.
For example:
141 07123 456789
Your number will be withheld for that call.
You need to use the code each time you want to hide your number on a call-by-call basis.
In the US, *67 is commonly used for a single call. Carrier documentation confirms that *67 can block caller ID for an individual call.
Because caller ID codes vary by country and network, check your carrier if the code does not work.
Method 2: Turn Off Caller ID on iPhone
Apple provides a built-in option for hiding your caller ID on iPhone.
To turn it off:
- Open Settings.
- Tap Apps.
- Tap Phone.
- Tap Show My Caller ID.
- Turn Show My Caller ID off.
After this, people you call will not see your phone number.
Method 3: Hide Caller ID on Android
Android phones can have different menus depending on the manufacturer, Android version, and mobile network.
On supported phones, the setting is generally found inside the Phone app’s calling settings.
A common path is:
- Open the Phone app.
- Open Settings.
- Look for Calling accounts or Call settings.
- Select your mobile network if required.
- Open Additional settings.
- Tap Caller ID.
- Select Hide number.
The exact menu can be different on Samsung, Google Pixel, and other Android phones.
If you cannot find the option, your carrier may control caller ID settings.
Method 4: Ask Your Carrier to Hide Your Number
If your phone does not provide a caller ID setting, your network provider may be able to enable number withholding.
Some providers allow you to hide your number permanently, while others provide a call-by-call option.
For example, BT allows customers to request permanent number withholding, while 141 can be used for individual calls.
Your carrier can also tell you whether hidden calls are supported on your specific plan.
What Is the Difference Between *67 and *69?
Here is comparison table:
| Code | Typical purpose | When to use it | Availability |
| *67 | Hide your number for an outgoing call | Before making a call | Carrier/country dependent |
| *69 | Return the most recent call | After receiving a call | Carrier/country dependent |
How to Call With No Caller ID on iPhone?
The simplest option on a supported iPhone is to use the built-in caller ID setting.
Go to:
Settings → Apps → Phone → Show My Caller ID → Off
Apple says that when this setting is turned off, the person you call will not see your phone number.
You can also use a supported caller ID blocking code for an individual call. In the UK, 141 is used to withhold your number for that call.
If the Show My Caller ID option is unavailable, contact your carrier.
How to Call With No Caller ID on Android?
Android gives you several possible ways to hide your number, but the steps are not identical on every device.
On supported phones, open the Phone app and look under its calling or supplementary settings for Caller ID. You may then be able to select Hide number.
How to Call Back a No Caller ID Number?
In most cases, you cannot directly call back No Caller ID number.
The reason is simple: your phone did not receive the caller’s number. Without those digits, your phone’s call history has nothing to redial.
Check Your Voicemail First
If the caller left a voicemail, listen to it before trying other methods.
A legitimate caller may identify themselves or provide another number to call.
If a callback number is included in the voicemail, use that number instead of trying to return the No Caller ID call.
What about 1471 in the UK?
For supported UK landline services, 1471 can tell you the last number that called.
However, it cannot reveal a number that the caller deliberately withheld.
So 1471 is useful for identifying an available caller number, but it does not unmask a genuinely withheld number.
What about *69?
*69 is a carrier-dependent last-call-return feature in some regions.
Its availability and behaviour vary by carrier and plan. It may return the last call without actually showing you the caller’s number.
For that reason, don’t assume *69 will reveal every No Caller ID number.
Why Would Someone Use No Caller ID?
People may hide their number for privacy.
For example, someone may not want the person they are calling to save or return their number.
Some organisations or individuals may also withhold their number when making outgoing calls.
However, a hidden number is not automatically suspicious.
The important thing is to consider the context of the call. If you receive repeated unwanted or threatening calls, keep records of the calls and any voicemails.
FAQs on No Caller ID Number
1. Does 141 hide your number?
Yes. In the UK, dialing 141 before a phone number can withhold your number for that individual call on supported services.
2. Does *67 still work on an iPhone?
The iPhone itself does not determine whether *67 works. Caller ID blocking codes depend on the network and country.
In the US, *67 is used to block caller ID for an individual call on supported services.
3. How to reveal no caller ID?
You generally cannot reveal a true No Caller ID number from your phone.
If the call is threatening or involves harassment, contact your carrier and the appropriate authorities rather than relying on an app claiming it can reveal every hidden number.
4. Can someone find no caller ID?
The person receiving the call normally cannot see the withheld number on their phone.
However, withholding your caller ID does not mean that the network has no record of the call. Carrier systems can retain call information.
Final Words – Calling with No Caller ID
Calling with No Caller ID is relatively simple when your phone and network support caller ID blocking.
In the UK, 141 is the standard call-by-call method for withholding your number. On supported iPhones, you can also turn off Show My Caller ID, while many Android phones provide a Hide number option in their calling settings.
If you’re trying to call back someone who used No Caller ID, things are different. You normally cannot dial the number directly because the caller’s number was not delivered to your phone.
If you receive an unwanted or threatening anonymous call, check your voicemail, keep a record of the calls, and contact your carrier or the appropriate authorities when necessary.
