Maybe you want to call someone but you don’t want them to know that you are calling from your mobile, it is a company, a service that you do not want to keep your number, maybe you want to play a joke on a friend… There are many occasions where you want to hide your phone number.
All SIM cards have an identifier, called a caller ID, so that all calls are traceable. This ID is sent along with the ringtone to the recipient, and thanks to that the caller can see the number before going off-hook. In this tutorial we are going to see how to hide the caller ID.
The method changes if you call from a landline or mobile, and also if you want to configure the hidden number permanently, on iOS or Android. So we are going to explain all the possible methods to you. All of them are very simple to carry out.
We started the tutorial to know how to call with hidden number on Android and iPhone in 2021.
Details to be considered
Before calling with a hidden number, you have to know a series of things so as not to get an unpleasant surprise later.
It is important to understand that hiding the number is not the same as making an anonymous call. As the name suggests, all we do is hide the number from the recipient, but the caller ID is still associated with the number itself. The phone company knows who made that call – if the recipient makes a complaint, a judge can ask the company to reveal the hidden number.
Hidden number calls do not work if you call the police or an emergency number (fire brigade, hospitals, etc.). In those cases the hidden number is deactivated, and the call is identified.
Many people and businesses automatically block calls made with a hidden number. If you hide your mobile you may not be able to call certain people or certain companies. They will not pick up the phone, nor will they find out that you called.
With that said, let’s see how to call with hidden number on Android and iPhone in 2021.
Hide the number on a landline phone
We can also call with a hidden number in landline also. Although they are less and less common in homes, there are still many people who have a landline phone in the living room or kitchen.
You can hide your number if you call from a landline, very easily.All you have to do is add the prefix 067 to the number you want to call. For example, if you want to call 932454442, you must dial: 067932454442.
The recipient will receive a call indicating Unknown, Number withheld, etc.
It may be that in some countries or operators instead of 067 they use # 67 or # 67 # although most likely all three will work. The most practical thing is to make a test call from the landline to your mobile, to check that it works.
Hide the number on an Android mobile or iPhone in a timely manner
The next option, more common nowadays, is to call with a hidden number from your mobile, on time.
For example, if we only want to hide a certain call, or only a recipient. This works whether you call from an Android mobile or from an iPhone.
Similar to the landline, all you have to do is add the prefix # 31 # to the call. For example, if you want to contact the number 619245721 you should dial: # 31 # 619245721
With some countries or operators instead of # 31 # it may work with * 31 #, or with both. The most practical thing, if you have two mobiles, is to call one to the other to check that it works. Or call a family member or friend and ask them to see if they can see the number.
Hide the number on Android in all calls
The above method is very simple to use, but it gets heavy if you want to use it multiple times. That is why there is the option to hide the phone number on Android in all calls.
The method changes depending on the version of Android you use, or if it is pure Android or the mobile has some layer of the operating system, so we are going to explain it in a generic way, and with an example.

Hide the number on Android in all calls
The above method is very simple to use, but it gets heavy if you want to use it multiple times. That is why there is the option to hide the phone number on Android in all calls.
The method changes depending on the version of Android you use, or if it is pure Android or the mobile has some layer of the operating system, so we are going to explain it in a generic way, and with an example.
As we have explained, each mobile number (the SIM card) has a caller ID. What you need to do is hide the caller ID.
We must open the call app ( Telephone ) on the mobile and touch the three ellipsis in the upper right corner, to access Settings.
The next step changes depending on the Android version. You have to try looking for something similar to Call Settings, and then enter Additional Settings or More Settings. Find the option Show my Caller ID or Show my caller ID and deactivate it, or check the Hidden Number option, if it exists.
For example, in pure Android from Android 8 you have to enter the Calls app and then in Settings, Call Accounts, touch on the SIM card, Additional Settings, and on Caller ID:
By deactivating the caller ID, from this moment all our calls will be hidden. When we want to be identified again we just go back here and activate the caller ID.
In some cases, as seen in the screenshot above, the caller ID is grayed out, and it won’t let you change it. This is because the operator has blocked the hidden call option on the SIM card. What you have to do is call the operator and ask them to let you hide the call from Android. It is free and they are required to do so.
If you have an online account with your operator, you can do it yourself. Enter your account and in the settings you will see an option that unlocks your caller ID and allows you to configure hidden calls from your mobile settings:
Hide number on iPhone in all calls
If you have an iPhone, the process is similar to Android. The goal is to find the option to hide the caller ID.
All you have to do is go into Settings , tap the Phone icon, and then Show Caller ID. Here you will see a switch. Disable it to hide your caller ID:
From now on, your number will not be seen when you call. When you want to be recognized repeat the steps and activate the caller ID.
As we have explained with Android, it is possible that your operator has blocked the caller ID on the SIM card, and these options appear gray, and cannot be changed. In that case, contact them and ask them to unlock the SIM to let you configure hidden calls. They are obliged to do it, and also free.
Hide the number through the operator
If you always want to hide your number, instead of configuring it through the mobile operating system, you can call your operator and ask that the default number be hidden from you.
The result is the same as doing it through Android or iOS as we have explained, but keep in mind that if you want to be recognized again, you will have to call again to ask your operator.
