How Spammers Get Your Phone Number and How to Protect Yourself

How do spammers get your number?

Today, almost every user encounters unwanted calls or text messages. We often receive notifications about unordered packages or unknown services, which naturally leads to the question: how did they get my number? The reasons are diverse; some are beyond our control, while in other cases, we inadvertently contribute to the sharing of our information.

One of the most common methods is data breaches. Even if you entrust your number to a reliable service or website, there is no guarantee that the platform will not become a target for hackers. Furthermore, there are "data brokers" who legally buy and sell consumer information. We often grant permission for this ourselves when registering for prize draws, loyalty programs, or filling out vague forms on websites where consent boxes are pre-checked.

Phishing and public data

Spammers frequently use phishing—a fraudulent method used to steal personal data. This can take the form of a fake job advertisement, a suspicious app, or a website that requests your number under the guise of authorization. Once this information falls into the hands of scammers, it spreads rapidly across the black market.

There are also instances where spammers obtain numbers from public sources. This may include corporate registries, property information, or various public directories. Some automated robocallers simply dial random sequences of digits to check if a number is active.

How to protect yourself

While it is difficult to protect yourself completely, there are several practical steps you can take to reduce the risks:

1. Smart registration: Always pay attention to which sites you register on. Avoid suspicious platforms overloaded with advertisements. Before signing up, look for reviews about the specific service.
2. Check your data: Use services like Have I Been Pwned to find out if your email address or phone number has been included in a data breach.
3. Limit publicity: Limit the public display of your number on social networks and public profiles as much as possible.
4. Search for your number: Occasionally Google your own number in quotation marks to see if it is available in the open web.

Although mechanisms for combating spam calls are still evolving in Georgia, digital hygiene remains the most important factor. The less you share your personal number on suspicious platforms, the lower the chance that it will end up in spammer databases.
