how to block a phone number on a landline

Are you a victim of spam and robocalls? Want to get rid of it? Learn how to blog a phone number on a landline by following just a few steps.  

Landlines are a staple for businesses and home use. However, this connectivity comes with its share of annoyances, primarily unwanted calls.  

Whether it’s telemarketers, robocalls, or plain spam, these calls disrupt our peace and pose potential risks.  

This blog aims to guide you through the various methods of managing these disturbances by effectively blocking unwanted phone numbers on your landline. 

Why Block Numbers on Your Landline? 

Blocking numbers on your landline isn’t just about avoiding minor annoyances; it’s a crucial step in safeguarding your privacy, enhancing your peace of mind, and improving your overall quality of life.  

Here are some of the most compelling reasons why you might consider blocking numbers on your landline: 

1. Privacy Protection 

Unwanted calls can be more than just a nuisance. They can also be a privacy risk. Telemarketers, scammers, and other unsolicited callers can use aggressive tactics that may infringe on your personal space and privacy.  

Blocking these callers ensures that your information remains confidential and that you are not disturbed by calls you do not wish to receive. 

2. Avoiding Scams 

One of the most dangerous aspects of unsolicited calls is the potential for fraud. Scammers often use robocalls or spoofed numbers to try to steal personal information, such as your credit card details, social security number, or other sensitive data.  

By blocking suspicious numbers, you reduce the risk of falling prey to these scams. 

3. Reducing Unwanted Disturbances 

Frequent unwanted calls can disrupt your daily routine, interrupt your work, disturb your rest, and generally be a source of ongoing irritation.  

Blocking these calls means that your time and your home environment are not continually interrupted by ringing phones, especially from callers who repeatedly target your number. 

4. Increasing Productivity 

For businesses, unwanted calls are not just annoying, but they can also be a significant drain on productivity. Employees spend valuable time dealing with irrelevant calls, which diverts their attention from more critical tasks. Blocking these calls helps maintain focus and efficiency at work. 

5. Mental Peace 

There is a considerable mental aspect to unwanted calls. They can cause stress and anxiety, particularly for individuals who may feel vulnerable.  

This includes the elderly or those who live alone. Knowing that these calls are blocked can provide a significant sense of relief and tranquility. 

Examples of Typical Unwanted Calls: 

  • Telemarketers: These calls are often made by companies attempting to sell products or services. They can be persistent and disruptive, particularly if they refuse to respect requests to be removed from call lists. 
  • Robocalls: These automated calls deliver pre-recorded messages and are used en masse to reach a large number of people quickly. They are often employed by political campaigns, charities, and scammers. 
  • Spam: This broad category includes any unwanted or unsolicited calls. They can vary widely but often involve callers from various operations that may not be trying to scam but are nonetheless intrusive 

Steps to Blocking a Phone Number on A Landline 

Here are some of the ways through which you can block a phone number on landline: 

1. Register Number With DNC (National Do Not Call Registry) 

One of the most straightforward and effective steps you can take to reduce unwanted calls on your landline is to register your phone number with the National Do Not Call Registry. This service is designed to help you cut down on telemarketing calls, but it’s important to understand how it works and what it covers. 

What is the National Do Not Call Registry? 

The National Do Not Call Registry is a service managed by the Federal Trade Commission (FTC) in the United States.  

It allows consumers to register their phone numbers to signal to telemarketers that they do not wish to receive unsolicited sales calls. The registry is intended to provide consumers with a choice about whether to receive telemarketing calls at home. 

How to Register at DNC? 

Registering your phone number is simple and free: 

  1. Online Registration: You can register online at the National Do Not Call Registry’s website (www.donotcall.gov). This method requires an active email address as you will need to respond to a confirmation email. 
  1. Phone Registration: You can also register by calling the registry’s toll-free number from the phone you wish to register. 

Once registered, your number stays on the registry until it is disconnected and reassigned, or until you remove it from the list. 

What Registration Covers? 

  • Telemarketing Calls: Once your number is on the registry, telemarketers covered by the FTC’s rules are required to stop calling you within 31 days (about 1 month). 
  • Exceptions: It’s crucial to note that registering with the Do Not Call Registry does not prevent all unwanted calls. Calls from or on behalf of political organizations, charities, and telephone surveyors are still permitted. Additionally, companies with which you have an existing business relationship can call you up to 18-months after your last purchase, delivery, or payment unless you ask them to stop calling you. 

Benefits of Registration at DNC 

Registering with the National Do Not Call Registry can significantly reduce the number of telemarketing calls you receive. This reduction can lead to fewer disruptions throughout your day, lower the risk of falling prey to telephone scams, and improve the overall peace of your home environment. 

While the Do Not Call Registry may not block all unwanted calls, it serves as a crucial barrier against many telemarketing pitches.  

Registering your phone number is an easy and effective first step toward regaining control over your landline experience. For complete protection, consider combining this registration with other call-blocking strategies and technologies discussed in our guide. 

2. Use *77 or *60 to Enable Anonymous Call Rejection 

Many landline providers offer a service known as Anonymous Call Rejection. By dialing *77, you can activate this service, which automatically blocks calls from numbers that have chosen to hide their caller ID.  

Note: Legitimate callers using private numbers might also be blocked, so inform friends and family to ensure their numbers are visible when calling. 

By dialing *60, you can block up to 12 phone numbers at once either typed manually or from the recent call list. Input #01# on the keypad to block recent calls. Dial# then insert the phone number followed by # to block a selected number. 

3. Subscribe to Call Blocking Services 

Your phone service provider may offer additional call-blocking services that can filter out robocalls or spam calls before they reach you. These services might include identifying and blocking high-risk numbers (like those frequently associated with fraud) or providing you with the option to screen calls based on risk level. 

4. Install a Third-Party Call Blocker 

If your landline provider doesn’t offer robust call-blocking features, or if you’re looking for something more advanced, consider purchasing a third-party call-blocking device such as CPR 100K.  

These devices can be attached to your phone and come with features designed to block known robocall numbers. Some models allow you to add numbers to a blacklist manually or automatically block numbers that aren’t on your whitelist. 

Devices like the CPR Call Blocker plug directly into your landline and allow you to block numbers with the touch of a button. Setting up is generally straightforward: 

  1. Connect the device: Attach it between your phone and the wall socket. 
  1. Program the blocker: Use the manual to program the device to block numbers or entire area codes. 

5. Employ Carrier-Specific Features 

Some traditional landline carriers offer features specifically designed to combat robocalls. For example, Verizon’s landline services include spam alerts and call blocking tools that can be activated through your account settings online or via customer service

6. Screen Calls Manually 

While more labor-intensive, manually screening calls can be effective, especially if you have a phone with a built-in answering machine or caller ID. Simply don’t pick up calls from numbers you don’t recognize—legitimate callers will usually leave a message. 

7. Educate Yourself and Your Family 

Awareness is one of your best defenses against robocalls. Educate yourself and your family members about how to recognize suspicious calls and the importance of not engaging with or providing personal information to unknown callers.

Adding Phone Numbers to a Spam List 

Whether through a traditional landline or a VoIP system, adding numbers to a spam list usually involves accessing your phone’s settings or using a web portal provided by your service: 

  1. Access your account: Log into your online account. 
  1. Navigate to call settings: Locate the call management or privacy settings. 
  1. Add to spam list: Enter the numbers you want to block.
