Whether it’s to protect your privacy, avoid getting called back in certain situations, or simply keep your personal number away from prying eyes, calling with a hidden number is easier than you think.

Calling with a hidden number for a single call: The code method
If you only need to hide your number occasionally, codes are your best friend. They’re quick, don’t require any setup, and work instantly. Perfect for that call where you’d rather fly under the radar.
Use the code *67 before the number you want to dial
This is the standard code for how to call with a hidden number in the United States and Canada. It works this simple:
- Open your phone’s dialer (the phone app)
- Type *67 followed by the number you want to call
- For example: *67-555-123-4567
- Hit call and you’re done
The recipient will see “Hidden Number,” “Unknown,” or “No Caller ID” on their screen. Easy, fast, and effective. This method works on both Android and iPhone, and it doesn’t matter if you’re using AT&T, Verizon, T-Mobile, or any other US carrier.
What happens if I dial #31#? The code for calling privately in other countries
Here’s an interesting fact: #31# is the code used in most countries around the world to hide your number when making calls. Although it sometimes works in the US (depending on your carrier), the official and most reliable code is *67 that we mentioned above.
If you see international tutorials talking about #31#, now you know that in the US you need to use *67 to ensure your call goes out with a hidden number. This way you avoid surprises and your privacy stays protected from the first attempt.
Remember: to make any call, even with a hidden number, you need to have your line active and with credit. Discover how easy it is to top up with doctorSIM and avoid interruptions when you need it most.
How to call with a hidden number from your phone’s settings
Would you prefer ALL your calls to go out with a hidden number without having to dial codes every time? Then what you’re looking for is to activate permanent hidden number from your phone’s settings. We’ll explain how to do it step by step on both Android and iPhone.
Set your number to hidden on an Android phone (Samsung and other brands)
The steps may vary slightly depending on your Android brand (Samsung, Google Pixel, Motorola, OnePlus), but the general path is as follows:
- Open the Phone app on your device
- Tap the three dots (⋮) or the Settings icon within the app
- Look for Call settings or Additional settings
- Go into More settings or Additional settings
- Select Show my caller ID or Caller ID
- Choose the option Hide number or Network default
And that’s it! From now on, every time you make a call, your number will appear as hidden automatically. If at any point you want to show your number again, just follow the same steps and select “Show number.”
Important note: Some manufacturers customize Android with their own interfaces (One UI from Samsung, Pixel UI from Google, etc.), so the menu names might change a bit. But the concept is the same: look in the phone app settings.
Activate hidden number on your iPhone
If you’re team Apple, hiding your number on iPhone is super straightforward. Apple makes it really easy:
- Go to Settings (the gear icon)
- Scroll down to Phone and tap it
- Look for Show My Caller ID
- Turn off the toggle (it should be gray/off)
From that moment on, all your calls will go out with a hidden number. To show your number again, just turn the toggle back on. Simple as it should be.
How to deactivate hidden mode and show your number again
Don’t want to call with a hidden number anymore? No worries, reversing the process is just as easy:
- On Android: Follow the same steps above and select “Show number” instead of “Hide number”
- On iPhone: Go to Settings > Phone > Show My Caller ID and turn the toggle on
And you’re done, your number will appear normally when you call. Total flexibility in your hands.
Have you configured everything but your call won’t connect? Sometimes, the most common problem is lack of credit. Explore our practical solutions to top up your phone instantly and keep your line always active.
How to call privately according to your phone carrier?
Although the codes and settings we’ve shown you work on virtually all carriers, each phone company in the US has its own particularities. Here are the details for the main ones.
Hide your number on AT&T
AT&T, one of the largest carriers in the US, is super compatible with the methods we’ve explained. The *67 code works perfectly for individual calls with a hidden number, and you can also activate permanent mode from your phone settings without any issues.
If you have AT&T and need to make sure you have credit for your private calls, topping up with doctorSIM is instant and secure. You’ll have your credit ready in seconds.
Call with a hidden number on Verizon
Verizon also supports the *67 code without any problems for making private calls. Whether you use a prepaid or postpaid plan, you can hide your number using the code method or by configuring your Android or iPhone system settings.
For Verizon users who want to keep their line active and ready to call whenever needed, topping up with doctorSIM is fast, reliable, and hassle-free.
Make a private call on T-Mobile
T-Mobile users can also use *67 before the number to make private calls occasionally, or configure their phone so all calls go out with a hidden number. The process is identical to other carriers.
Pro tip: Regardless of your carrier, make sure you have coverage and sufficient credit. A private number protects your identity, but it doesn’t exempt you from needing active service to complete the call.
Why can’t I call with a hidden number? Possible causes and solutions
You’ve followed all the steps to the letter, but your hidden number call simply won’t work. What could be happening? Here are the most common causes and their solutions:
1. You don’t have credit or your line is inactive
This is reason number one. Even if you’ve configured your hidden number perfectly, if your line doesn’t have credit or is suspended, you won’t be able to make any calls. Quick solution: recharge your phone with doctorSIM and try again.
2. The recipient has blocked calls from hidden numbers
Some phones and carriers allow automatically blocking all calls from hidden numbers. If the person you’re calling has this feature enabled, your call won’t go through. In this case, you’ll have to call showing your number.
3. You’re calling an emergency number or special service
Emergency numbers (911, etc.) and some customer service lines don’t accept calls with hidden numbers for security reasons. It’s a protection measure you can’t bypass.
4. Your carrier doesn’t support this feature on your specific plan
Although it’s rare, some very basic or old plans might have restrictions. Contact your carrier to verify if your plan allows calls with hidden caller ID.
5. You dialed the code incorrectly
It seems obvious, but it happens: make sure you’re using *67 (and not #67 or any other variation) followed immediately by the number, without spaces. For example: *67-555-123-4567.
6. Problem with your phone’s configuration
If you activated permanent hidden number but it’s not working, try turning it off and on again. Sometimes a simple reset of the configuration fixes internal conflicts in the operating system.
7. Your phone is in airplane mode or has no signal
Without coverage, there’s no call to be made, private or not. Verify that you have signal from your carrier before trying to communicate.
All set up and ready to call? Remember that keeping your line active is essential to use all these features. With doctorSIM you can recharge your phone in seconds and from anywhere, without complications or endless lines.
