How to Block Spam Calls: A Comprehensive Guide


Spam calls have become a pervasive nuisance in today’s world, disrupting our daily lives and causing unwarranted irritation. These unwanted calls can range from annoying telemarketers to fraudulent scams, posing threats to our privacy and financial security. Fortunately, there are several effective methods we can employ to block these intrusive calls and reclaim our peace of mind. This comprehensive guide will provide detailed instructions on how to block spam calls on various devices and platforms, empowering you to take control of your communication channels.

Identifying Spam Calls

Before we dive into the blocking techniques, it’s crucial to understand the characteristics that distinguish spam calls from legitimate ones. Here are some telltale signs:

  • Unknown or unfamiliar numbers: Spammers often use spoofed or unfamiliar numbers to avoid detection.
  • Robo-calls: Automated messages delivered through robocall systems are a common tactic used by spammers.
  • Unwanted sales pitches: Calls offering unsolicited products or services, especially from unfamiliar companies, are likely spam.
  • Requests for personal information: Spammers may attempt to trick you into sharing sensitive information such as your Social Security number or credit card details.
  • Sense of urgency or pressure: Spam callers often use high-pressure tactics to coerce you into taking immediate action, such as making a purchase or providing personal information.

Blocking Spam Calls on Smartphones

Smartphones have made it relatively easy to block spam calls. Here are the steps for popular operating systems:

iOS Devices (iPhone, iPad)

  • Open the "Phone" app.
  • Tap the "Recents" tab.
  • Find the spam call you wish to block.
  • Tap the "i" icon next to the number.
  • Scroll down and tap "Block this Caller."

Android Devices

  • Open the "Phone" app.
  • Tap the three-dot menu in the top-right corner.
  • Select "Settings."
  • Tap "Blocked numbers."
  • Tap the "Add a number" button and enter the spam caller’s number.

Third-Party Call Blocking Apps

For additional protection, you can consider using third-party call blocking apps available on both iOS and Android devices. These apps often offer advanced features such as automatic spam call detection, customizable blocking lists, and reverse number lookup. Some popular call blocking apps include Truecaller, RoboKiller, and Hiya.

Blocking Spam Calls on Landlines

Blocking spam calls on landlines requires a different approach, as smartphones’ built-in features are not available. Here are some methods:

Contact Your Phone Service Provider

Most phone service providers offer call blocking services as part of their subscription plans. Contact your provider to inquire about their specific call blocking options and instructions.

Use a Call Blocking Device

Dedicated call blocking devices are available for purchase and can be connected to your landline. These devices typically have customizable blocking lists and advanced filtering algorithms to screen out spam calls.

Register on the National Do Not Call Registry

The National Do Not Call Registry (DNCR) is a government-maintained list that allows individuals to opt out of receiving telemarketing calls. Registering your landline number on the DNCR will significantly reduce the number of legitimate telemarketing calls you receive, but it will not block all spam calls.

Blocking Spam Calls on Other Platforms

Spam calls can also penetrate other communication platforms such as:

Voice over Internet Protocol (VoIP)

If you use a VoIP service for your home or business phone, check if it offers call blocking features. Many VoIP providers have built-in spam filters or allow you to add numbers to your personal blocklist.

Social Media Platforms

Social media platforms like Facebook and Instagram have implemented measures to combat spam calls. If you receive spam calls from someone you don’t know, report them to the platform and block their account.


Spam calls can also originate from email addresses. To block these calls, use an email filtering service that identifies and blocks spam emails.

Best Practices for Preventing Spam Calls

In addition to blocking spam calls, there are proactive measures you can take to minimize their occurrence:

  • Avoid sharing your phone number publicly: Limit the distribution of your phone number to trusted sources.
  • Be cautious when providing your number online: Only provide your number on reputable websites and forms.
  • Use a disposable phone number: Consider getting a separate phone number for non-essential purposes, such as online registrations or public Wi-Fi access.
  • Educate yourself: Stay informed about the latest spam call tactics and report any suspicious activity to the appropriate authorities or online resources.


Spam calls are an unwelcome nuisance that can be effectively managed by implementing the blocking techniques outlined in this guide. By blocking spam calls on our smartphones, landlines, and other communication platforms, we can reclaim control of our communication channels and enjoy a more peaceful digital experience. Remember to adopt proactive measures to minimize the occurrence of spam calls and report any suspicious activity to help reduce this growing problem.
