# Spam calls origin and prevention methods revealed

Spam calls have become a frustrating reality for many people around the world. These unwanted calls can be annoying and even lead to financial losses. The question on everyone's mind is: how do robocallers get our phone numbers in the first place?

There are several ways that spammers obtain phone numbers, and unfortunately, some of these methods are beyond our control. Data breaches are a common occurrence, where sensitive information, including phone numbers, is stolen from online accounts or databases. When this happens, spammers can easily access the compromised data to make unsolicited calls.

Another way robocallers get hold of our numbers is through sheer chance. This can happen when we use our phone number for an important account or service, only for that site to be targeted by a spammer. Alternatively, illegal callers may randomly dial numbers or obtain them from public records such as court directories or corporate filings.

In some cases, spammers may also get hold of our numbers through online marketplaces where they can purchase lists of phone numbers. These lists often contain numbers obtained through data breaches or other illicit means. It's worth noting that even if we take steps to protect ourselves, there's no guarantee that our number won't be compromised in the future.

The fact is that stopping spam calls requires a combination of prevention and vigilance. By understanding how spammers get hold of our numbers, we can start taking steps to mitigate this problem. In part two of this series, we'll explore some practical tips for reducing unwanted calls and protecting your phone number from falling into the wrong hands.

Even if you're registered on the Do Not Call Registry, which restricts most telemarketing calls, you can still be targeted by certain groups exempt from this regulation. These include charities, political parties, debt collectors, and telephone surveyors.

The majority of phone numbers available to spammers have been obtained through data brokers who resell this information to third parties. This often occurs when individuals sign up for accounts, loyalty programs, contests, or sweepstakes, with the sale of their contact details being a mandatory condition or hidden in fine print on web pages.

Signing up for services or entering contests can also lead to your number being sold, even if you didn't explicitly agree to this. Phishing scams are another common way that phone numbers end up in the wrong hands, as victims unwittingly provide their information while trying to use a fake login page or sign up for a bogus app.

As devices offer some protection against phishing attempts through browser warnings and enhanced security features like Android's bank scam defense, there are still steps you can take to safeguard your number.

To minimize the risk of having your number exposed online, exercise caution when using public websites and avoid ones that are cluttered with advertisements or unfamiliar.

When creating accounts on these sites, be mindful of which personal details you share, including whether to hide your phone number on public profiles. Additionally, be cautious about how many accounts you create and the information you provide for each one.

Signing up for the FTC's registry can also help limit unwanted calls from robocallers. To investigate how your number may have been compromised, search for any associated account breaches by entering your email address into a site like Have I Been Pwned, or try googling your phone number in quotes to see if it appears anywhere online.
