What Are Spam Calls?
Spam calls are unsolicited phone calls made to your number, often with the intent to deceive, sell, or promote unwanted services. These calls are typically from telemarketers, scammers, or automated systems (robocalls) and are often a nuisance for individuals and businesses alike.
While some spam calls aim to market legitimate products or services, others are designed to commit fraud, steal personal information, or spread malicious content. For example, someone might call you saying you owe back taxes or compel you to sign up for dubious subscriptions.
Spam calls have become very common in recent years. Every year, billions of spam calls are made around the world. Not only do they waste time, but scams can also put people’s safety at risk if they fall for them. It is important to know how to spot these calls to protect your privacy.
Why Do Spam Calls Occur?
Spam calls occur because scammers, telemarketers, and businesses use them as a cost-effective way to reach large audiences. Spammers can make millions of calls every day at minimal expense due to advances in technology like auto-dialers or robocalls.
Multiple reasons lead to spam calls. Telemarketers may use them to sell offerings. Scammer phone calls also use them to convince people to give out sensitive information like credit card numbers or social security details. Fraudulent calls often use psychological tactics, like making people feel like they need to act quickly.
In some cases, spam calls stem from companies obtaining your contact details through data breaches, online forms, or public directories. Spammers often target random numbers, hoping for responses from unsuspecting recipients.
Spam calls are always a problem because there aren’t strict rules around the world alongside spoof caller IDs. Using call-blocking tools can help lessen their effects.

How to Report a Spam Number?

Reporting spam numbers is an important way to stop spam calls and keep other people safe from possible scams. Here are some good ways to report a spam number through various channels.
Use Caller ID Apps
Many caller ID apps, like Truecaller and Hiya, allow you to report spam numbers directly. If you get a suspicious call, mark it as spam in the app. This tells other users about the modification by updating the app’s information.
Report to Your Phone Carrier
Most mobile carriers, such as AT&T, Verizon, and T-Mobile, provide options to report spam. For example:
- AT&T users can forward spam texts to 7726 (SPAM).
- Verizon customers can report by forwarding spam messages to the same number or using the Verizon Call Filter app.
Report to Regulatory Authorities
In the U.S., you can report spam numbers to the Federal Trade Commission (FTC) via the Do Not Call Registry. Other countries have similar organisations, like Ofcom in the UK or TRAI in India.
Report Online
Websites like Spamhaus, 800Notes, or WhoCalledMe allow users to log spam numbers and share their experiences. These platforms create public records, making it easier for others to identify spam.
Use Social Media
Talk about any suspicious user behavior you have seen on Twitter or Reddit to help to user community awareness.
How to Protect Yourself from Spam Calls?
Spam calls can be disruptive and potentially dangerous if they lead to scams. Here are effective strategies to protect yourself from these unwanted intrusions:
Use Call Blocking Apps
Install apps like Truecaller, Hiya, or RoboKiller to automatically identify and block spam calls. These apps maintain updated spam databases and help you screen calls effectively.
Enable Built-in Phone Features
Most smartphones have built-in spam detection tools. For example, iPhones can silence unknown callers. Android phones have call-blocking settings that can be used to filter suspicious numbers.
Avoid Answering Unknown Numbers
If you don’t recognise an incoming caller, let it go to voicemail. Spammers usually won’t leave a message, but legitimate callers will leave a message.
Be Cautious with Personal Information
Never share sensitive details, like your social security number or bank account information, over the phone. Phone scammers often use urgency to trick you into revealing such data.
Register on the Do Not Call List
Sign up for the National Do Not Call Registry (in the U.S.) to reduce telemarketing calls. While it won’t stop all spam, it adds an extra layer of protection.
Report Spam Numbers
Report suspicious unknown phone calls to your carrier, regulatory authorities like the FTC, or spam-reporting platforms. This helps improve spam databases and protect others.
What to Do If You Fall Victim to a Spam Call?
Falling victim to a spam call can be distressing, but quick action can minimise potential damage. Follow these steps to protect yourself and prevent further harm:
Stay Calm and Assess the Situation
Take a moment to know what information or device access you may have provided. Did you share personal details like bank information, passwords, or social security numbers? Knowing this will guide your next steps.
Secure Your Accounts
If you’ve shared sensitive information, immediately change your passwords for related accounts. Enable two-factor authentication (2FA) to add an extra layer of security. For financial accounts, monitor transactions closely and notify your bank of potential fraud.
Report the Incident
- To Your Bank: Inform them about any compromised account details to block unauthorised transactions.
- To Regulatory Authorities: In the U.S., report scams to the Federal Trade Commission (FTC). Other countries have similar agencies, like Action Fraud in the UK.
- To Your Phone Carrier: Report the scam phone number to a mobile phone service provider to help improve spam detection services.
Check for Malware
If you clicked on any suspicious links, scan your device for malware using trusted antivirus software.
Warn Others
Share your experience on platforms like 800Notes, social media, or with family and friends to help others avoid falling victim to the same scam.
7 Tips for Avoiding Spam Calls

Spam calls are not only annoying but can also pose risks to your personal and financial security. Here are practical tips to minimise and avoid spam calls effectively:
1. Don’t Answer Unknown Calls
If you don’t recognise the caller, let the incoming phone call go to voicemail. Genuine callers will leave a message, while spam callers often won’t.
2. Register for the Do Not Call List
In the U.S., sign up for the National Do Not Call Registry. While this doesn’t block all spam calls, it reduces telemarketing calls significantly.
3. Use Spam-Blocking Apps
Install apps like Truecaller, RoboKiller, or Hiya to identify and block spam calls. These apps rely on user-reported databases to screen incoming calls.
4. Activate Built-in Phone Features
Use your phone’s built-in settings to block spam. For instance, iPhones can silence unknown callers, and Android phones offer spam detection tools.
5. Don’t Share Your Number Publicly
Avoid posting your personal phone number on public platforms like social media or online forms unless necessary. Spammers often harvest numbers from these sources.
6. Be Wary of Giving Out Information
Never provide personal details like bank account numbers or social security information over the phone, especially to unsolicited callers.
7. Report Suspicious Calls
Report spam phone numbers to your phone carrier or regulatory agencies like the FTC. This helps improve spam detection for everyone.
