Do you have your mobile number linked to several social media accounts? There are chances that you may end up making your phone number visible to the public. As you know, showing up your phone number in public may land you in trouble.
All of us have to call many people in our daily life and most of them may be almost unknown to us. Showing up your personal number to an unknown person may cause various incidents of malicious attacks and threat. So, it is very important to block your caller ID to keep your phone number private.
Here are the few methods to keep your 10-digit phone number displaying as “Private Number” to everyone you are going to call.
Use a USSD Code to Block Caller ID
You are allowed to enter a code before dialing a number in many countries so your phone number will appear as “Private Number” and can be blocked from appearing on their caller ID. The code varies as per the service provider and the country. Well, you cannot do this in all countries. Simply enter the code followed by the 10-digit number you are dialing. For example, if you want to call (555)123-4567 in the US, you may like to enter *675551234567.
Here are the codes based on countries –
- North America – #31# or *67
- Germany – #31# or *31
- Argentina, Switzerland, Iceland, South Africa – *31*
- Albania, Denmark, Australia, Greece, Italy, Israel, Sweden, Netherlands, Norway – #31#
- Hong Kong – 133
- Japan – 184
- Ireland and UK – 141
- New Zealand – *67 (Vodafone) or 0197 (Telecom)
