Americans receive 4.3 million unwanted calls per month, according to Consumer Reports. There are several options to block your calls from unwanted numbers from reaching you on your landline phone. These options vary depending on your phone service provider and what calls you are trying to block.

Blocking Unwanted Calls From Calling Your Landline

You have a few options for blocking unwanted calls on your landline depending on which unwanted calls you want to block, whether from telemarketers, spammers, robo-callers, or all unknown numbers.

To Block Telemarketers, Use the National Do Not Call Registry 

The National Do Not Call registry is a service from the Federal Trade Commission (FTC), the national consumer protection agency, that aims to help people receive fewer unwanted sales calls. When you add your phone number to the registry, it goes on a list that is shared with registered telemarketers and signals which numbers they cannot call.

The problem with the Do Not Call registry is that it only works with companies that are registered as telemarketers and choose to follow the law. Organizations calling for political, charity reasons, debt collection, and surveys do not need to follow the Do Not Call registry. And of course, it does not deter scammers who operating illegally.

To Block Spammers, Use a Spam Number Database Blocker 

To solve the problem of all other unwanted calls that you get on your landline, some people have tried to compile databases of numbers that spammers use so that you can mass-block those numbers from calling you. On a cellphone, there are apps that will block numbers in these databases from reaching you. On a landline, there are some devices you can purchase that will block these numbers. These solutions however, are not effective because scammers are always using new phone numbers.

To Block Robocalls, Use Robocall Blocking 

Robocall blocking is the most effective way to block spam calls from reaching your home, and it requires no intervention from you. When people or robo dialers call your landline, usually they hear a ring, then you pick up. For robodiallers, picking up is the signal that they "have a live one"--- they'll either connect you with a human you don't want to talk to or play a recording you don't want to listen to. A robocall blocker requires callers to push a button before they can be connected with you. Human callers can do this easily, but it's impossible for robodiallers. That means that scammers and telemarketers who use robodiallers will never be connected with you.

Community Phone's Robocall Blocking feature block virtually all spam calls. Here's how it works: When someone calls you, they will hear "This is a Robocall Blocker. Press 1 to connect." When they press 1, the call will ring your phone. Given that almost all robocall systems cannot press 1, this blocks virtually all spam calls.

To Block All Unknown Callers, Use a White List 

Sometimes you may want to have even more control over who can call your phone number. By using a white list, also called an allow list, contact list, or approved caller list, only callers that you have approved can get through to you on your phone. Other numbers would be blocked or sent straight to voicemail. Many cellphones have this option, but it is not usually available on a landline phone. However, Community Phone does have a white list technology available to its landline customers. Community Phone's Complete Spam Blocking service blocks 100% of calls from numbers that you have not approved.

Blocking Specific Phone Numbers on Landline Phones

Many phone service providers advertise the ability to block calls from unwanted numbers. Generally what this means is that they offer users the ability to block calls from a set number of phone numbers, sometimes as few as 10 or 12. This can be useful in some cases, but generally does not make a meaningful difference in the amount of spam calls you receive. This is because spam callers use thousands of different numbers and are always creating more.
