What Does Unknown Caller Mean?

When you receive a call from an ‘Unknown Caller,’ it indicates that the service operator has not been able to identify the number that called you.

When you receive a call from an unknown number, it is likely the caller is calling from another country or that the caller has a network issue. Still, it is rarely a sign that the caller deliberately hides their number.

The unknown caller label appears on your screen when your carrier’s service operator cannot collect enough information to identify the caller.

Have you ever been in the middle of a conversation with someone when your phone suddenly says “Unknown Caller”? It’s not just a random glitch – there’s a reason why your phone does this.

When you receive a call from an unknown number, your phone checks that number against a database of numbers that are known to be associated with telemarketers, scammers, and other nuisance callers. 

If the number is found in that database, your phone will display “Unknown Caller” instead of the caller’s name or number. Usually, these are spam calls that you don’t want to answer. Occasionally, they will leave a voicemail you can listen to later if it’s something important.

Other Spam Protection Features

Most wireless carriers offer free spam protection for iPhones. If you must pay for additional spam protection, we do not recommend it. Our list below highlights the spam prevention options offered by the major carriers.


For T-Mobile users, you can use a few shortcodes in the Phone app to block unwanted spam calls. 


Enter #662# in the Phone app to block Scam Likely calls. By entering #787#, you can see whether you have already enabled this feature. Lastly, if you wish to turn off this feature, you must type in the number #632 to do so.


Most Verizon phones and plans are compatible with Verizon’s Call Filter service. You can protect your phone from spam calls with Call Filter, Spam Detection, and Spam Filter.

Some spam calls can also be routed directly to voicemail, depending on their risk level. While Verizon provides a free version of this service but offers a premium version for $3 a month with even more protection.


The AT&T Mobile Call Protect app, which you can download from the app store, offers further spam protection. Spam and Fraud Call Blocking, Unknown Call Blocking, and personal Block Lists are all included in the free version of this app.


A premium version of this service is available for $3.99/month through AT&T, similar to Verizon’s Call Filter service. However, we believe that paying for extra spam protection is unnecessary.


Is It Dangerous To Answer Unknown Calls?

Yes, It is dangerous to answer unknown calls.  Generally, most phone calls you receive are benign and nothing more than a nuisance, but you should always be cautious if you receive an unknown call.

Obviously, You should not answer these calls. Your carrier will charge you a hefty fee if you answer the number you cannot see due to scammers. In addition, if the caller were genuine and had important information to share, they would leave a message.

Who Is The Unknown Caller? Can My Telephone Provider Tell Me?

Providers cannot reveal an unknown caller’s name. If not, user privacy could be violated, and legitimate callers could get scammed. You cannot get this information from a carrier, either the one who provides your cellphone or the one that provides your landline, because both do not track unknown callers.



You can protect yourself from unknown callers, but they can be a nuisance. The best way to avoid these calls is by not answering them, and if you must, using a blocking service.
