4 Ways to Block Spam Calls on a Landline

Updated: Jan 31

Getting unwanted calls on your landline? Learn how to block spam, robocalls, and telemarketers.


Dealing with spam and robocalls is a pain. While cell phone numbers tend to be safer, home phone numbers remain a source of spam calls for thousands of Americans. According to a recent report cited in the Washington Post, Americans received 26.3 billion robocalls in 2018, up 46 percent from the previous year.


This blog will cover the four most common ways to get rid of unwanted calls on your landline number. To be clear, none of these methods will guarantee that your number will become 100% spam-free, but they can go a long way.


After implementing these tactics on our business number, we reduced our spam-calls by more than 80%. How did we do it?


1. Check if your service provider offers any spam-blocking features

2. Add Your Number to the national Do Not Call Registry

3. Sign up for Nomorobo (free for landline users)

4. Switch to a service that automatically blocks all spam calls for you



1. Check if your service provider offered any spam-blocking features.


The first place you will want to check is with your provider to see if they offer any anti-spam software.


Verizon has a great page with step by step solutions, all of which are covered later in this article.


On AT&T landlines, you can block unwanted calls from up to 100 numbers by pressing *61 after your most recent unwanted incoming calls.


2. Add Your Number to the Do Not Call Registry.


The Do Not Call Registry is a government-managed, do not call list. The purpose of the list is to protect folks from unwanted telemarketers. However, these calls are usually from legitimate businesses (the only ones who respect the government guidelines). So while that may take care of some of your telemarketer calls, it won't do anything to prevent robocalls or foreign spammers.


3. Sign up for Nomorobo (free for landline users)


Nomorobo is a free third party service that can identify known spam callers and automatically block the calls before they get to your phone. Depending on your exact landline service, you may be eligible to sign up.



The steps to signing up with Nomorobo are:

  • Go to Nomorobo.com and signup

  • Set Up Nomorobo through the link that is sent to your email*

  • Log into your Phone Management Portal

  • Click Activate in the Nomorobo section of the Phone Management Portal

  • Read the Nomorobo description and click Acknowledge; this will activate the simultaneous ring

  • Return to Nomorobo's website to complete the registration process

4. Switch to a service that automatically blocks spam calls for you


Sometimes you've tried all these options and continue to receive spam calls. In that case, we recommend moving your number to a service provider that specializes in spam blocking.


One of those carriers is NumberDock. NumberDock uses a Call Forwarding system that allows them to filter spam calls before they reach you.


They start by parking your landline number, which means it is no longer tied to your physical landline device. Once it's parked on their system, they forward only legitimate inbound calls to your cell phone number.


Folks who call your number will be greeted by a message that says, "press 1 to confirm you are not a telemarketer" it then forwards the call to your cell phone after a correct press.


This service guarantees you will not receive robocalls and greatly reduces telemarketer calls. It also replaces your existing landline provider for less - meaning most folks save money by moving to NumberDock.
