How to Reduce Spam on Your Main Phone Number

Calls from unknown numbers, SMS, advertising banners on websites, or directly in the smartphone interface — most of us have encountered this at some point. This happens because we live in a time of rapid technological growth. Scammers are gaining more and more freedom and tools, and companies are increasingly trying to push their products or services.

Almost all of spam types can be dealt with, but it requires the appropriate knowledge and tools.

Below, you’ll find more information about spam and its real danger, as well as practical tips to help reduce the amount of spam on your primary phone number.

What is Spam?

Spam refers to unsolicited, usually mass-distributed messages sent without a user’s consent. It can be emails (such as junk mail or “spam emails”), text messages, calls, social media comments, Telegram scams, and other forms of online or offline communication. The purpose of spam may vary: it can be commercial, aimed at promoting goods or services, fraudulent, with the aim of deceiving users, as well as political, social, or other.

How Does Your Number End Up in Spam Databases?

Scammers and spammers get phone numbers in a variety of ways. For example:

• Data breaches. Users provide their phone numbers when registering on various websites or when making purchases in online stores. If the scammers manage to gain access to the databases, they will also steal user information.
• Data scraping. People often indicate contacts on social networks, on personal websites or forums, on bulletin boards. Spammers collect phone numbers and use them to make phone calls.
• Database leaks or insider data sales. Unscrupulous employees of companies and services may intentionally transfer data to third parties. Fraudsters often acquire databases on the dark web or even on the open internet.
• Random phone calls. To collect the database, they can use automated systems (robocalls) that calls random numbers. If the subscriber answers, it confirms the existence of the number.

*Note: No one is immune from getting into the spam database. Any owner of a phone number can receive an unwanted call.

What is the Danger of Spam Calls?

The purpose of spam is obvious — to sell goods or services and expand their audience. Of course, the method chosen is illegal. But most of the time, the main downside is wasted time and the importunity of spammers.

#1 Financial Fraud

Fraudsters present themselves as employees of various services or representatives of banks. They ask you to urgently pay a fine or debt, to pay for any service used. As a rule, they provide payment details and the victim personally transfers the money to the attackers.

#2 Theft of Financial Data

A spammer may ask you to confirm your bank account information, ask for your bank card details, or provide a code from the message. With this information, fraudsters can access your finances. As a result, money will be stolen from the account or any payments will be made.

#3 Identity Theft

In this case, the attackers are trying to find out information about you and your loved ones. The questions may vary: place of residence, income level, family ties, and so on. The data obtained can be used for various purposes — gaining access to your online accounts, deceiving your relatives, and using personal information in various fraudulent schemes.

#4 Voice Phishing (vishing)

During the conversation, spammers try to get the answers they need. For example, they ask questions that are most likely to be answered with “Yes” or “No.” Scammers record the voice to use it later. For example, attackers can call your loved one and play back-recorded audio to gain the victim's trust.

Useful Tips to Reduce Spam on Your Main Phone Number

If you don't want to receive endless spam and put yourself and your data in danger, then it's time to reduce or eliminate it altogether. Here are some practical tips that will help with this.

1. Use a Virtual or Temporary Number Instead of a Personal One

Instead of using your personal number when signing up on various online resources, it is recommended to use a virtual or temporary number. This allows you to get a phone number without entering your personal data. Additionally, it gives you the ability to filter or block all unwanted incoming messages or calls. Thanks to this, you do not need to use your personal phone number to register an account, verify your identity, etc., without fear of endless spam.

Keep in mind that it is essential to choose only trusted temporary numbers for these goals. For example, Getempnumber.com has a wide base of affordable and unused numbers that are suitable for registration on most online platforms. But some another unproven services can suggest you unworking or dangerous numbers that can’t be used even once.

2. Use Specialized Mobile Apps to Block Spam

Such apps can identify who is calling you and block unwanted calls that appear in the constantly updated spam list. There are many such apps on the Google Play Store, so you can choose any one you like, ranging from free to premium options with advanced features and filters.

For example, applications such as Truecaller, which help identify unknown numbers and automatically blocks spam, are popular, as well as Hiya, a convenient tool with a powerful filtering system and protection against fraudulent calls. As a result, using such applications can significantly increase the level of digital security and keep you calm in your daily life.

Block Spam Calls Directly on Your Phone

If, for some reason, you don't want to use third-party apps to block spam calls and messages, then try blocking them through your smartphone settings.

➤ For iPhone

In newer versions of iOS (13 and later), there is a “Mute Unknown” function, when activated, all numbers that are not in your contacts and with which you do not have a history of calls and SMS messages are automatically transferred to the answering machine. Unfortunately, this is not always convenient, because you can miss an important call from a caller with whom you have no “history”.

How to enable:

Go to Settings → select Phone → scroll down → turn on the “Mute Unknown” feature.

➤ For Android

Blocked numbers on Android are done manually only:

• Go to “Calls” or “Phone”, click on the three dots in the upper right corner.
• Then go to “Settings” and select “Number Lock.”

*Note: You will have to block each number you don't need separately.

Final Word

Unfortunately, there is almost no chance for an advanced digital user to avoid spam in 2026. The only thing that can be done is to do everything possible to minimize its impact on the user and their data. Therefore, it is important to take your data seriously and not disclose it on unverified resources or transfer it to third parties. In addition, it is essential to use various methods to prevent spam and remember that your security is your area of responsibility.
