Over the last few years there has been a surprising resurgence in the number of people who are using landline phones. While cell phones are now the dominant form of phone in the world, landlines have become more popular as they are considered a more private and less stimulating form of telephone use. However, for as much as simply using a landline can be less stimulating, there is one problem that remains: Unwanted calls.

Whether you have certain people in your life that you do not wish to speak with on the phone, or if you have found yourself dealing with annoying robocalls the fact remains that unwanted phone calls are a universal problem. Blocking a phone number on a cell phone is simple enough, whether you use Android or iPhone. However, some may find blocking unwanted numbers and area codes to be unfamiliar ground given that landline phones do not have a similar interface to cell phones.

Don’t worry, because here you will learn the important steps to blocking unwanted phone calls on your landline phone.

To block a phone number on a landline, first check if your service provider offers call-blocking features. Many providers offer a service called Selective Call Rejection that lets you block unwanted numbers directly from your phone. Start by picking up your phone and dialing *60 (or a similar code if your provider uses a different one). Once connected, you’ll hear instructions for blocking numbers, usually by pressing a few keys and then entering the unwanted number.

If call blocking isn’t available through your provider, another option is a call-blocking device. These small devices attach to your phone line and can block specific numbers, entire area codes, or even unknown calls. Call-blocking devices are simple to set up and can store a large number of blocked numbers, giving you control over which calls come through without needing extra services from your provider.
