No one needs to know your phone number, especially when calling suspicious companies or strangers. block Caller ID on Phone is easy and can protect you from unwanted spam calls and emails.
When you make a call on your iPhone, Caller ID lets the other party know your phone number, and if you want to know how to make a private call on your iPhone and prevent Caller ID from showing up, there are several ways.
Here are three ways to hide your phone number, who can still see your phone number after using these methods, and an easy way to make your phone number reappear on every call, even if you blocked it. Let’s get started and learn how to block a phone number on your iPhone.
How to Block Caller ID on Phone
Dial *67 Before the Number You Want to Call
The easiest way to block a number is to dial *67 at the beginning of the number you wish to call. If you want to use this method to hide your caller ID from someone stored in your contacts, you must first write down (or copy to the clipboard) their number. Then manually type (or paste) it into the phone app, prefixing it with *67.
When you call someone using 67, it will show up on their device as “No Caller ID”, “Private”, “Blocked” or similar. Calling someone using this technique is a good way to see if they have blocked your number.
Change the Caller ID Settings on Your Phone
You can block the number by changing the settings on your device to hide the caller ID each time you call, and on both Android and iOS devices, you can hide the caller ID so that the person you are calling will see no caller ID, private, or Blocked.
If, after changing these settings, you wish to temporarily unblock your number, dial *82 before the number you wish to call. This will overwrite the settings and the caller ID will reappear. This is a good method to use if you cannot easily call a private phone number and you want the person to call you back.
On iPhone
- Open the Settings app and scroll down to tap on the Phone option.
- Tap Show My Caller ID, then turn the toggle off to hide your number.
On Android
- Launch the Phone app and open the Menu in the top-right corner.
- Go into Settings, then scroll down to Supplementary Services. Depending on your particular device, you may need to go to Calls > Additional Settings.
- Tap Show my caller ID and choose to Hide number from the popup men
Block Your Caller ID Directly With Your Cell Carrier
If you cannot find an option to block numbers or hide caller ID in your phone’s settings, you must instead block numbers directly with your mobile carrier. Many carriers that do not allow you to set up blocked numbers in your device settings allow you to set up blocked numbers using their own apps. If not, you will need to call your mobile carrier and ask them to block the number.
As with the previous method, blocking the number in this way will hide the caller ID every time you make a call. If you want to disable this and display the number on certain calls, you will need to add *82 to the beginning of the number.
What is Caller ID?
Caller identification is a feature built into telephones that identifies incoming callers by phone number (and sometimes name). This feature provides a digital display and uses caller identification technology and online databases to recognize callers before they receive a call. Caller ID technology is not perfect and may occasionally provide incorrect information.
The name can display up to 15 characters and the mobile number up to 10 digits, a feature that is required by nearly all commercial telephone providers, including VoIP, landline, and cellular phone services.
How Does Caller ID Work?
When Caller ID was made, most people used Plain Old Telephone Service (POTS) lines. The information about who was calling came through the Central Office switch, which was connected to the wires. At the time, there were not that many carriers, so it was easy to find Caller ID information and pass it along.
With the rise of wireless and VoIP phones, hundreds of local and long-distance phone companies, consolidations, mergers, and other changes, the map is now much more broken up. Unlike phone numbers and domain name service (DNS), for which there are authoritative databases, there is no central authority or regulation for Caller ID.
