What does hiding your caller ID do?
Normally, when you place a call, your phone number is displayed on the recipient’s phone. We all have caller ID nowadays, but there are situations in which you want to block your phone number when you’re making a call. Luckily, hiding your phone number is easy to do.
When you block your caller ID, you prevent the person on the other end of the line from knowing it’s you that’s calling. This person will only see ‘anonymous’, ‘private number’ or ‘unknown caller’, or something similar on their caller ID instead of your phone number.
You can use hiding caller ID permanently or just for a single phone call. In the latter case, your next call will display your caller ID as normal.
Bear in mind: you can’t hide your caller ID when you’re making a call to certain phone numbers, such as emergency services. Operators of emergency call centers are always able to see your number, so they can call you back when your connection is poor or if you hang up in a panic.
Code to hide your caller ID
If you’re in a situation where you quickly need to hide your phone number, you can easily use a code or prefix to do so. If you’re from the United States, for example, you enter *67 before you dial the phone number you want to call. The code depends on the country or region you’re from.
Codes by country for mobile phones
|Austria||#31# or *31#|
|Brazil||#31# or *31#|
|Canada||#31# or *67|
|Czech Republic||#31# or *31#|
|Finland||#31# or *31#|
|Germany||#31# or *31#|
|Hungary||#31# or *31#|
|Netherlands||#31# or *31*|
|New Zealand||*67 (Vodafone)|
0197 (Telecom or Spark)
|Norway||#31# or *31#|
|Poland||#31# or *31#|
|Portugal||#31# or *31#|
|Romania||#31# or *31#|
|South Korea||*23 or *23#|
|Ukraine||#31# or *31#|
|United States||*67 (all carriers except AT&T)|
|Other countries||Use code #31#|
Using a code or prefix is the quickest way available, plus it’s completely free. The proceedings are simple:
- First enter the code, for example *67
- Then, enter the actual phone number you want to call
- Place the call as you normally would
For example, if you’re calling the US-number 444-333-2222, you dial *674443332222 to mask your number. If it doesn’t work, try entering #31# or *31# instead. Your number should appear as ‘private’ or ‘unknown’.
It might be smart to first make a test call and make sure you’ve completed the steps in the right way. The trick is temporary, which means you should do this procedure for each individual call. It is time-consuming if you want to block your caller ID more often.
How to hide your caller ID on iPhone
Most phones, such as the iPhone, also allow you to hide your caller ID on a more permanent basis. If you want to hide your caller ID on your iPhone, there are several ways to do so. You can block your caller ID for a single call, depending on which carrier you’re using, or you can change your phone’s settings to permanently disguise your phone number.
Do you want to make an anonymous phone call? Try this:
- Open ‘Settings’
- Click on ‘Phone’
- Click on ‘Show My Caller ID’
- Turn the option off
Your caller ID remains hidden as long as you don’t switch the button back on. Remember: some phones do not accept calls from blocked numbers, so be sure you know how to turn the option off and make your identity known again!
Do you want to switch your caller ID to anonymous for an indefinite period of time? Then contact your service provider and ask about permanent caller ID blocking. Don’t forget to check about added expenses: perhaps masking your ID permanently isn’t worth the while if it will cost you heaps.

How to hide your caller ID with Google Voice
Another possibility is hiding your Google Voice number, so the people you’re calling won’t see it:
- Open the Voice app
- Tap Menu Settings at the top left
- Turn Anonymous Caller ID on under calls
When the need to call anonymously has vanished, you can easily turn Anonymous Caller ID off by following the opposite steps. Keep in mind that hiding your caller ID on one device hides it on all devices that are linked to your Voice account.

- Before dialing the phone number as you usually would, you enter the prefix for blocking your caller ID.
- Dial the phone number after entering the prefix
The person you’re trying to reach won’t see it’s you calling.
How to use a burner number app to hide your caller ID
All the above-mentioned actions are quite easy to follow and they are great for a quick, anonymous phone call. However, if you’re serious about hiding your caller-ID for the long run, there are better solutions. Such as a burner phone number, which also allows you to hide your personal phone number when texting or sending images.
If you use an app like Burner, you can easily sign up for a second phone number that will send incoming calls and text messages straight to your regular phone.
The perks? Your personal number remains private and nobody who tries to contact you knows you’re trying to hide your phone number. This way, you’re able to protect your privacy without anyone noticing because they see ‘private number’ or ‘anonymous caller’ popping up on the screen.
It makes sense when you think about it. In work situations, for example, when you want to maintain the balance between your private life and those incoming work-related phone calls. Or when you’ve just met a potential lover through Tinder or some other dating app and don’t want them to know your real phone number.
It’s clear: with the Burner app, you’re always safe and anonymous when you give out your phone number!
