Do you want to protect yourself or your kids from being targeted by scammers? Definitely yes, nowadays, many people like you are experiencing the same issue of receiving calls from private numbers ( having no caller ID). However, kids, especially because of their trusting nature, are easy targets of such scam calls. So, you might be wondering how to block private numbers?
Thus, in this guide, we’ll provide you with a detailed tutorial for blocking private numbers on both Android and iPhone devices.
What are private numbers?
Private numbers are actually the calling feature that allows you to call others without even revealing your phone number. Basically, when you call, the person would only see the names like Private, No Caller ID, etc. on their screens. That’s what you call a privacy feature in which you stay anonymous owing to many positive or negative reasons.
For your information, people usually benefit from this anonymity by turning on their Hide caller ID feature from their phone settings. Also, the other option is that they may use some code like *67 (US/Canada) or #31# (many countries) just in front of before the number they’re calling.



Difference between private, unknown, and restricted calls
In normal voice calling, there are usually three options before you, like you may receiving a private call, an unknown call, or a restricted call. All these types are totally different from each other. For instnace;
- Private calls, as mentioned earlier, knowingly hide their identity.
- On the other hand, when you receive unknown calls, then it’s not true to think that the person is hiding their identity. This is because it’s actually the network that shows something like unknown on your screen, as it’s unable to recognize this number.
- Similarly, talking about the restricted calls, in this case, it is the organization or company itself that has locked the caller ID. That’s basically used by the Government hospitals, businesses, law enforcement, or emergency services, etc. They make such calls to hide their number so people don’t disturb them by calling back.
/ | What does it mean? | How does it appear on the Phone? | Common examples |
Private | Caller intentionally hides their number | “Private,” “No Caller ID,” or “Blocked” | Someone calling from a personal number, an online seller, business owner |
Unknown | The network cannot identify the number | “Unknown” or blank | International calls, network glitches |
Restricted | Caller ID blocked at the service level | “Restricted” | Government offices, hospitals, secure business lines |
Why block private numbers?
Now, let’s dive deeper and understand the logical reasoning why people like you decided to block the private numbers!
Avoid telemarketing and scam calls:
Telemarketers mostly use private numbers to promote their products, whether gadgets or any offer via calling. Although they are legal, if they call you repeatedly, then you may get irritated.
Also, there are scammers who pretend to be from the bank. And ask you to give sensitive information like your ID card number, etc. So, if you give such info, then your money would get stolen. Thus, as you see, the person is calling with the private tag appearing on your screen, then block that number right away.
Reduce harassment and repeated unknown calls:
Furthermore, some people may call you via a private number just to harass you. So, they sometimes repeatedly call you without fearing of being traced. Thus, by blocking them, you would feel relaxed and make sure that only the trusted persons would contact you.
Protect children from strangers and inappropriate contact:
Also, children, because of a lack of awareness, quickly answer the calls that they receive. So, the strangers once find that there is a child with this number. Then they would call them back and might distract them.
Thus, blocking private numbers would protect children from getting in touch with strangers.
