The great Nordic conquerors earned their place in history with their hot blood and confrontational nature. Less is said about their prudence and cool heads, which were also necessary in many situations to avoid leaving their fate to chance. We want to focus more on promoting these more thoughtful attitudes. So, if calls from unknown sources are bothering you, we'll help you find out who's trying to reach you. Check the mobile phone number, who it belongs to, and how to block it if needed.

Why are unknown numbers calling you?

Many commonly used digital platforms offer free access. Social media is the simplest example. Requests for consent to receive commercial information when registering on various websites and mobile applications have also become standard. Sometimes you also have the chance to receive a discount code in exchange for leaving your contact details.

Just as various precious metals were currency in Viking times, data has become currency in the 21st century. The above example illustrates the brightest side of this phenomenon. After all, the terms are clear and transparent. You receive specific value by sharing your phone number and email address. This is how you can get on the radar of marketers who will call you from time to time.

Unfortunately, sometimes you have no control over who suddenly contacts you with an offer in the 'too good to refuse' category. Perhaps there will be an uncontrolled data leak from a company to whom you entrust your details. Some entities also buy databases or use software that automatically generates phone numbers. In such circumstances, there is more room for privacy violations.

How to check a phone number for free in the simplest way?

By default, a phone rings for 20-30 seconds. If you don't answer, the call attempt is terminated. It might seem like a short time. However, being as quick as Thor's lightning ⚡, you'll manage to check who's trying to contact you and even answer if the number successfully passes your verification.

When the phone rings, simply minimize the call screen, go to a web search engine, and type or paste the number there. There's a good chance that the owner has already been identified by other users who have revealed their identity on various websites. This way, you'll usually find out which company the marketer was calling from.

Based on this information, you can quickly decide whether you want to talk or prefer not to answer. After the call ends, you'll be able to quickly block the number if you want to avoid further contact attempts. You don't need any special tools for this. The native functions available on any smartphone are entirely sufficient.

Websites allowing free phone number checks

There are a number of worthwhile websites that allow you to check who called you. You'll certainly come across one of them when you want to quickly verify a number that's currently displayed on your screen. However, it's also worth checking these sites in less urgent cases. This way, you'll learn more about many phone numbers that remained in your call history. For verification, we recommend, among others, the following websites:

A big advantage of these websites is open access to sharing information. Anyone can add a rating and a comment revealing more details about the number's owner. This way, you'll not only avoid annoying marketers but also dangerous attempts to lead you astray.

Find the phone number owner with the help of mobile apps

If you need a heavier caliber tool, it's time to discover new lands 🌍. Check out the Play Store or App Store and search for the following applications:

  • Sync.me,
  • Hiya,
  • TrueCaller.

Each of the listed suggestions offers a wide range of functionalities for verifying and managing incoming numbers. Among the available information is: origin, mobile network, and also the owner's data. What's more, you don't have to check these apps after the fact. You'll see the information as soon as the phone starts ringing and the number appears on the screen. In practice, a warning against spam or an attempted scam might appear there. It's also worth using these apps if you're wondering how to block a phone number. With the help of the available tools, you'll be able to do it immediately.

And when you want to be incognito…

Everyone has probably seen an unknown number calling on their phone display. Perhaps then you dreamed of using such clever techniques. So, if you're wondering how to block your number, we're here to help. You can do it once or permanently. In the first case, just dial #31# before the number you want to call. The entire sequence should look like this #31#123456789.

If you want to use this option permanently, go to your phone's settings. The option you're looking for might be "Show my Caller ID" or similar. The name may vary slightly depending on the smartphone manufacturer. Simply uncheck this function to maintain greater anonymity when making calls.  

Remember, however, to exercise caution when using this solution. Many people treat a blocked number as an alarm signal 🚨. There is therefore a significant risk that this time you will become the prey instead of the hunter, and you will end up on someone's blacklist.
