8. How To Block Restricted Calls On Android Or iPhone1

In this post, we’ll define restricted calls (also known as anonymous calls) and show you how to stop them using both built-in features and third-party apps.

Owners of mobile phones frequently and abusively receive Restricted Calls (Unknown Calls). No matter if you use an iPhone or an Android phone, there are ways to prevent them from contacting you in the future.

What is a Restricted Call?

When a person or business wants to prevent the person they are calling from seeing their number, it is known as a restricted call. In most cases, when a call is placed, caller ID will display a name or a number.

This data will also be recorded in your phone’s call log. This information won’t be given if the number is restricted, so the caller will remain anonymous. Additionally, these calls may appear as anonymous in your phone log, and you might not even be able to see the details on your monthly bill.

The ability to trace and block these restricted calls has gotten harder as technology has advanced.

When a Phone Number is Restricted, What Does It Mean

Simply put, it means the person who is calling you has asked for their caller ID to be hidden. Most carriers allow you to activate this feature either permanently or on a per-call basis by dialing a code. That implies that the caller is either blocked from accessing private personal information or is still blocked, regardless of whether it is a debt collection agency, an organization that needs to receive money from you, or an organization that needs to receive information from you.

As suggested above, you can restrict your own number by dialing a code *67 (Your mobile number will temporarily be disabled, as will your caller ID (start with star 67). It implies that, on the receiving end, your number will be displayed as “Unknown” or “Private Number”.

What’s the Deal With Restricted Calls?

When a person or business doesn’t want the person they are calling to know who they are or be able to track the call back to them, they typically use restricted calls. The feature is typically offered as a simple-to-use service that is made available by all telecom providers.

Entering *67 before making a call is one of the more popular methods for enabling a restricted call. What will happen is that the call will go through as normal, but with “restricted,” “unknown,” or “private” appearing instead of your actual phone number.

But if you’re calling a friend, you’d probably prefer that they answer and see that it’s you. Who exactly is it then that needs to hide using this feature?

Who Uses Restricted Calls?

This strategy is most frequently employed by robocalls, telemarketers, and bill collection companies, although some people may use it as an additional measure of privacy. That’s not to say that every time a restricted call is placed, it’s done so to defraud the recipient of the call of money.

In an effort to maintain anonymity, the caller has chosen to disable their caller ID. Someone you know and trust shouldn’t bother to hide their phone number, so it doesn’t make much sense for them to do so.

As a result, the caller is probably someone you don’t know or someone you’re attempting to avoid. This prompts the query of what to do in the event of a restricted call.

Should You Answer Restricted Calls?

Even though it won’t always be one, the chances of it being a scammer or bill collector on the other end of a restricted call are fairly high. Answering a call from someone trying to pass as someone else is similar to opening your door to someone wearing a mask. Although it’s not a given that it will go wrong, the likelihood that it will turn out well is also low.

The best course of action when receiving a restricted call is to ignore it and, if the caller is really eager to speak with you, allow them to leave a voicemail. If restricted callers do not leave a message outlining the reason for their call and how to contact them, the call was probably made by a scammer or robocall.

Restricted Call Blocking by Service Providers

Verizon offers its own app (application) for call blocking on mobile devices, just like many other carriers. The “Call Filter” app of The call blocking options offered by Verizon are numerous. The ability to manually block specific numbers, alerts that let you know when a call might be spam, and a way to mark numbers as problematic are all available.

Incoming calls from those most likely to be fraudsters are intercepted and blocked by AT&T “Call Protect”.

Cell Phone

Cell phones can make it a little trickier to try to block restricted calls than landlines do. The most crucial element is the service provider you use for your phone.
