Learn How To Stop Robocalls on Your Landline

Understanding Robocalls and Why They Target Landlines

Robocalls are automated telephone calls that deliver a recorded message. According to the Federal Communications Commission (FCC), Americans received approximately 3.8 billion robocalls in 2023, with landlines representing a significant portion of these unwanted calls. Landlines are particularly vulnerable targets because they are often listed in public directories and are easier for automated systems to reach compared to mobile numbers.

Robocalls fall into several categories. Some are legitimate, such as appointment reminders from your doctor's office or delivery notifications from retailers. However, many robocalls are fraudulent. Common types include tech support scams claiming your computer has been compromised, IRS impersonation schemes demanding immediate payment, mortgage refinancing offers, credit card interest rate reduction pitches, and lottery or prize award notifications. Scammers choose landlines because they know these numbers reach households with established billing histories and sometimes older adults who may be more susceptible to their schemes.

The technology behind robocalls is relatively simple and inexpensive. Scammers purchase lists of phone numbers, use Voice over Internet Protocol (VoIP) services to make calls at minimal cost, and employ calling software that can dial thousands of numbers simultaneously. The caller ID can be spoofed, meaning the number displayed on your phone may be completely fake or may impersonate a legitimate organization. This spoofing makes it difficult to identify the true source of the call.

Understanding the mechanics of robocalls helps you recognize them when they arrive. Robocalls typically have several identifying characteristics: they begin with a brief pause before a recorded message plays, they often come from unfamiliar numbers, and they frequently call at inconvenient times. If you recognize these patterns on your landline, you are likely receiving robocalls rather than legitimate calls from people you know.

Practical Takeaway: Robocalls targeting landlines are automated calls using technology that is inexpensive to operate. Recognizing the characteristics of robocalls—such as pauses before a recorded message begins—helps you identify them when they reach your phone.

Federal Laws and Regulations That Protect Landline Users

The Telephone Consumer Protection Act (TCPA), enacted in 1991, is the primary federal law governing telemarketing calls and robocalls in the United States. The TCPA established the National Do Not Call Registry, a free list where consumers can register their phone numbers to reduce unwanted telemarketing calls. The FCC, which oversees the TCPA, maintains this registry. Registering your landline on the Do Not Call Registry means that telemarketing calls to that number should stop within 31 days, though legitimate calls (such as those from charities, political organizations, and debt collectors) are exempt from this requirement.

In addition to the Do Not Call Registry, the TCPA prohibits calls made using automatic telephone dialing systems or artificial or prerecorded voices to cell phones without prior express consent. For landlines, the rules are somewhat less restrictive, but calling using prerecorded messages is still regulated. Callers must provide certain information when they call, including a clear identification of who they represent and a callback number. Robocallers often violate these requirements by not providing this information or by providing false information.

The FCC has strengthened regulations in recent years. In 2020, the FCC adopted rules requiring phone companies to implement caller ID authentication technology, known as STIR/SHAKEN (Secure Telephone Identity Revisited/Secure Handling of Asserted information using toKENs). This technology makes it harder for scammers to spoof caller IDs. However, implementation has been gradual, and not all phone companies have fully deployed these systems.

Other relevant regulations include the CAN-SPAM Act, which applies to text messages and some forms of electronic communications, and state-level laws that may provide additional protections. Some states have stricter requirements than federal law regarding robocalls. For example, certain states require prior written consent before any prerecorded calls can be placed to residents.

If you receive a robocall that violates these laws, you may have the option to file a complaint with the FCC or your state's attorney general. The FCC collects complaint data about robocalls and uses this information to identify patterns of illegal calling activity and to prioritize enforcement actions.

Practical Takeaway: Federal laws like the TCPA and the Do Not Call Registry provide legal protections against unwanted robocalls. Registering your landline on the National Do Not Call Registry (at donotcall.gov) is a first step to reduce telemarketing robocalls.

Technical Solutions Your Phone Company Can Provide

Most landline providers offer call-blocking features designed to reduce robocalls. These services vary by provider, but they generally work by filtering incoming calls against databases of known robocall numbers and patterns. Major landline providers including AT&T, Verizon, CenturyLink, and local telecommunications companies often offer robocall filtering at no additional cost or for a monthly fee, typically ranging from $3 to $5.

Call-blocking services work in different ways. Some services silently block suspected robocalls before they ring your phone. Others send suspected robocalls to a separate voicemail box or alert you with a label on your caller ID indicating that a call is likely spam or fraud. Services like AT&T Call Protect, Verizon Call Filter, and CenturyLink Call Manager use machine learning algorithms that analyze calling patterns and call characteristics. When a call matches the pattern of a known robocaller, the service acts to block it or flag it.

To use these services, you typically need to contact your phone provider and request the feature. Some providers automatically include basic robocall filtering at no charge, while premium versions with more aggressive blocking require activation. The process is usually handled through a phone call to customer service or through your provider's online account management portal.

In addition to provider services, some consumers use third-party call-blocking apps that work with certain landline systems. These apps, such as RoboKiller, Whoscall, or Nomorobo, analyze incoming calls and use databases to identify and block suspected robocalls. However, the compatibility of these services with traditional landlines varies. Some work through your internet-connected landline system, while others may not be compatible with older analog landline technology.

An important consideration is that no call-blocking service blocks all robocalls perfectly. Scammers constantly change their tactics and phone numbers to evade filtering systems. Additionally, some legitimate callers may be incorrectly blocked, so it is worth periodically checking with your phone company about whether any legitimate calls you expected are being blocked.

Practical Takeaway: Contact your landline provider to learn about their robocall filtering services, which often are available at no cost or for a small monthly fee. These services filter calls before they reach your phone by comparing incoming calls to databases of known robocall numbers and patterns.

Manual Blocking Techniques and Call Management Strategies

Beyond using service-provided filters, you can take manual steps to block specific robocallers and reduce overall robocall volume. The simplest method is to use your landline phone's built-in call-blocking feature if it has one. Many modern landline phones, particularly those that are internet-connected or digital, have a menu option allowing you to block specific numbers. When you receive a robocall from a particular number, you can block that number directly through your phone's settings or control panel. Blocked calls will either not ring through to your handset or will be sent to voicemail.

Another manual technique involves not answering calls from unknown numbers. While this may seem obvious, many people instinctively pick up any call on their landline. Robocallers rely on people answering to either deliver their recorded message or, in the case of live scammers, to begin their pitch. If you do not recognize the number, letting the call go to voicemail allows you to screen it. Robocalls often do not leave voicemails, so an absence of a message is a good indicator that the call was unwanted. Legitimate callers usually leave a message.

You can also use your voicemail greeting strategically. A greeting that provides your name and asks callers to leave a detailed message may deter some robocalls, as robocallers prefer reaching a live person. Setting up a dedicated voicemail password also prevents unauthorized access to your messages.
