How to block a telephone number on an iPhone
To block a telephone number on an iPhone, open the Phone app, tap "Recents," tap the "Info" button (i) next to the number, scroll down, and tap "Block this Caller" or "Block Contact." This stops calls, texts, and FaceTime from that number, giving you immediate relief from unwanted contact. For a more comprehensive approach to blocking calls and numbers, iPhones include a "Silence Unknown Callers" feature, found in Settings > Phone, which automatically sends calls from numbers not in your contacts to voicemail without ringing. This is ideal if you're getting a lot of spam or robocalls, as it filters out anyone you haven't explicitly saved, while still letting calls from your contacts come through normally. You can also enhance call identification by using information from supported carriers and third-party call identification apps, which can be enabled in Settings > Phone > Call Blocking & Identification.
How to block a telephone number on an Android phone
You can block a number on a smartphone by navigating to your call log, selecting the number, and choosing the option to block or report spam. On Android devices, you can generally block a number by opening the Phone app, navigating to "Recents" or "Call history," selecting the unwanted number, and choosing a "Block" or "Block/report spam" option. This is the quickest way to stop a specific number from bothering you, and reporting it as spam also helps your carrier identify the caller for other users. Many smartphones allow users to create custom block lists to proactively block multiple numbers simultaneously. For blocking calls from unidentified callers, the steps vary slightly by manufacturer. On Google Pixel phones, open the Phone app, tap the three dots (More options) > Settings > Blocked numbers, and toggle on "Unknown" or "Block calls from unidentified callers." On Samsung Galaxy phones, you'll find a similar option within the Phone app settings under "Block numbers," where you can enable blocking for unknown or private numbers. These settings are perfect if you only want to hear from people you know.
What happens when you block a number
When you block a number on a mobile phone, calls from that number typically go directly to voicemail, and text messages will not be delivered. The blocked caller usually does not receive a notification that they have been blocked, so they won't know unless they try to call or text and notice a lack of response. This means you can silently stop the communication without any confrontation.
Blocking a number on a landline phone
Blocking a telephone number on a landline is a straightforward process, though it depends on your specific phone model and service provider. Most landline phones offer call-blocking features that allow you to prevent specific numbers from reaching your phone; you typically access the phone's settings or features menu, navigate to the call-blocking option, and enter the number you wish to block. Some landline phones play a busy signal or a message that the call cannot be completed to the blocked caller. Some landline phones also allow you to block anonymous or private numbers, adding an extra layer of protection. If your phone doesn't have built-in blocking, your service provider likely offers call-blocking services as part of your package, which you can manage through your account portal or by contacting customer support.
Using third-party apps to block calls
Both iPhone and Android platforms support third-party call blocking and identification apps, which can offer more comprehensive spam detection and blocking capabilities. These apps are especially useful if you're dealing with a high volume of robocalls or want more control over your call filtering, as they often maintain extensive databases of known spam numbers and update them regularly. You can download these apps from your device's app store, and they integrate with your phone's settings to provide an extra layer of defense beyond the built-in options.
