Receiving No Caller ID or unknown calls that you don’t want can be bothersome. When the calls don’t have a number on your phone, the users become victims, therefore knowing how to block calls without a caller ID on your phone is essential. This is because some unwary people have been victims of cyberbullying, which began when they answered a call from a caller whose ID was obscured.
What are the aims behind ‘no caller ID’ or spam calls, and where do they come from? Why are they so bothersome, and how do you get rid of them on your smartphone? These questions are satisfactorily answered in this article. To protect yourself and your personal information, all you have to do is pay attention to the 5-minute read and be prepared with many strategies to block these anonymous callers and unknown calls.
What is Caller ID?
Caller ID is a phone feature that, if available, displays the name and phone number of the person who is calling. The feature isn’t perfect, and it can occasionally mislead the identity of a caller. Caller ID, on the other hand, is a useful piece of information in most cases. It’s available from nearly every commercial phone company, including landline, VoIP, and mobile phone services.
Caller ID, unlike local number portability (LNP), is not governed by a regulatory body like the Federal Communications Commission (FCC). Rather, the service is a patchwork of decentralized databases that frequently operate with out-of-date data.
Are No Caller ID Calls Dangerous?
Calls with “No Caller ID” indicate that the person who is phoning you has hidden their phone number. This suggests they don’t want you to have their phone number or be able to trace the call back to them. Telemarketers, nonprofit groups, and other individuals may make these calls to ask you to buy something or even steal your information and money.
More severely, even answering a single question from an unknown caller can be risky. It puts you at risk of becoming a voice phishing victim. This kind of scam is perpetrated when the person on the other line records your voice whenever you answer “yes” to their question. If the scam is successful, the scammers can use your voice recording to impersonate a customer and authorize fraudulent charges.
Differences between Unknown Caller and No Caller ID
Unknown Caller and No Caller ID are similar, but there are major differences between them.
Unknown Caller refers to a call from a phone number that cannot be identified by your service provider. You will see “Unknown caller” is displayed when your mobile phone screen. This may be caused by technical issues of your service provider or spam risks. Some scammers or spam callers may use a fake or temporary phone number, which can appear as an Unknown Caller.
No Caller ID means the callers purposefully block their caller ID from being displayed. The callers may block their Caller ID with a third party tool or by dialing a special prefix before the phone number they want to call. The caller can be scammers, spammers, marketers or someone who want to prank you. Sometimes, they may just not want to reveal their phone number for privacy.
Can You Trace No Caller ID Calls?
Tracing a call from a “No Caller ID” can be challenging, as the caller purposely cover up their identity. However, there are still some methods that may help to find out who calls you.
- Use *57: If you’re in the US, you can use the *57 feature, which is a call trace service. Dial *57 after receiving a call from a No Caller ID number. The next time the number calls, it will be traced and the police will have the information they need to track down the caller.
- Use a caller ID app: There are some caller ID apps that can help to reveal some kinds of no caller ID calls.

Can You Call a No Caller ID Back?
