Blocking unwanted calls on a landline can be a great way to regain control over your phone and protect yourself from annoying or harassing callers. Whether you’re receiving telemarketing calls, spam calls, or calls from someone you simply don’t want to speak to, blocking their number can provide you with peace of mind and a more peaceful phone experience.
There are several methods you can use to block a number on a landline. One option is to contact your telephone service provider and inquire about their call blocking services. Many providers offer call blocking features that allow you to block specific numbers or even entire area codes. This can be a convenient and effective way to stop unwanted calls from reaching your landline.
If your service provider doesn’t offer call blocking, or if you prefer a more hands-on approach, you can also consider using a call-blocking device. These devices can be connected to your landline and provide you with the ability to block unwanted calls. Some call-blocking devices allow you to manually enter the numbers you want to block, while others have pre-programmed lists of known spam or telemarketing numbers.
Another option to block a number on a landline is to use a call-blocking app. These apps are available for smartphones and can be connected to your landline through a Bluetooth or Wi-Fi connection. Once connected, you can use the app to block specific numbers or even create a blacklist of unwanted callers. This can be a convenient option if you prefer to manage your call blocking settings from your smartphone.
Method 1: Contact Your Service Provider
If you want to block a number on your landline, one of the easiest ways to do so is by contacting your service provider. Most service providers offer call blocking services that allow you to block specific numbers from calling your landline.
Step 1: Identify the Number
The first step is to identify the number that you want to block. Make sure you have the complete and accurate number before contacting your service provider.
Step 2: Contact Your Service Provider
Once you have the number, call your service provider’s customer support line. Explain that you want to block a specific number from calling your landline and provide them with the details of the number.
Step 3: Follow Provider’s Instructions
Your service provider will guide you through the process of blocking the number. They may ask you to provide additional information or may simply activate the call blocking service for you.
Step 4: Test the Block
After the call blocking service has been activated, test it by asking someone with the blocked number to call your landline. If the call is successfully blocked, you have successfully blocked the number.
Step 5: Additional Options
Some service providers may offer additional options for call blocking, such as blocking calls from private or unknown numbers. If you want to block these types of calls as well, ask your service provider about the available options.

Method 2: Use a Call Blocker Device
If you’re tired of receiving unwanted calls on your landline, using a call blocker device can be an effective solution. These devices are designed to block incoming calls from specific numbers or types of calls, such as telemarketers or robocalls. Here’s how you can use a call blocker device to block a number on your landline:
Step 1: Purchase a Call Blocker Device
The first step is to purchase a call blocker device that is compatible with your landline phone. There are various call blocker devices available in the market, so make sure to choose one that meets your requirements.

After connecting the call blocker device, you will need to set up call blocking. This can usually be done through the device’s settings or by using the provided instructions. You may need to enter the specific number you want to block or choose from a list of blocked numbers.
Step 4: Test the Call Blocking
Using a call blocker device can provide you with peace of mind and help you avoid unwanted calls on your landline. It’s a convenient and efficient way to block specific numbers or types of calls without relying on your service provider.
Pros | Cons |
---|---|
Effective in blocking unwanted calls | Requires purchasing a separate device |

Provides peace of mind | May not block all unwanted calls |
Overall, using a call blocker device is a reliable method to block a number on your landline. It gives you control over the calls you receive and helps you maintain your privacy.
Method 3: Manually Block Numbers
If you prefer a more hands-on approach, you can manually block numbers on your landline. Although this method may require more effort on your part, it can be an effective way to block unwanted calls.
Here are the steps to manually block numbers on your landline:
- Identify the unwanted number: Before you can block a number, you need to identify the specific number that you want to block. This can be done by checking your call history or caller ID.
- Access your landline settings: Depending on your landline phone model, you may need to access the settings menu. Look for an option that allows you to block or reject calls.
- Add the unwanted number to the block list: Once you have accessed the settings menu, locate the option to add numbers to the block list. Enter the unwanted number and save the changes.
- Test the block: To ensure that the number has been successfully blocked, ask a friend or family member to call you from the blocked number. If the call is rejected or blocked, then you have successfully blocked the number.
If you continue to receive unwanted calls even after manually blocking numbers, you may want to consider contacting your service provider or using a call blocker device for additional protection.
By following these steps, you can take control of your landline and prevent unwanted calls from disturbing you.
