The phone sounds, you look at the screen, and there is a number that you have not saved. This leaves no message. He doesn’t call anymore. And you stay with the unknown: who was it? The company wants to sell something? Anyone who is marked by mistake? Contact of the past? Interview? The most obvious way to find out is to call back, but this is not always a good idea. Today, the return of an unknown call can be left expensive … literally. Fortunately, there are safer and more effective ways to find out who called you without noting. Here we say how.
Why don’t you answer the call?
Before entering the solution, it is convenient to understand why it cannot be the best. In some cases, these lost calls come from numbers, which are part of telephone fraud. When the call is returned, they can direct you to special tariff lines that charge high amounts per minute, or you can confirm that your number is active, which leads to a larger number of spam attempts. Therefore, the most reasonable is a small investigation.

Activate spam protection on your mobile phone
One of the fastest ways to filter unknown calls is to take advantage of what is already appearing on your mobile phone. Many smartphones include spam protection directly in their telephone application. This function analyzes incoming numbers, and if it discovers that a person is associated with advertising challenges, warns you before answering.
Brands such as Samsung, Xiaomi, Realme, Vivo and Google Pixel integrate this function. To activate it, follow these instructions.
Step 1: Open the Call application on your phone.
Step 2: Go to the configuration or settings (the icon of three vertical points).
Step 3: Look for an option Call the identifier and antispam (or some kind of similar) and ACT.
At the same time, even if you do not have a saved number, a mobile phone can tell you whether it is a company, a well -known institution or potential fraud. This is a very useful level of security.
Use specialized applications
If your phone does not have a good detection of unwanted challenges or if you want to take another step further, there are applications specifically designed to help you determine unknown numbers. The most famous is Truecaller.

This application (available on Android and iOS) shows you information about the number that you call you, allows you to block unwanted calls and works with a rather extensive database that is constantly updated. Of course, keep in mind that for functioning you need access to your list of contacts and calls that may not have the taste of each in terms of confidentiality.
Use it if you get a lot of suspicious calls, especially if you do not want to check each Google number manually.
Old Search for Google
We cannot underestimate the force of simple search on the Internet. Many times, if this number is connected with the company, service or reported on forums such as spam, it will appear in the first results. This method does not require installation and is quite effective.
Step 1: Open Google from your browser.
Step 2: Copy the full number (with the code of the country, if you have) and take it in the search field in Google. Example: +56 9 1234 5678.
Step 3: Read the results. Many times you will find forums, complaints about spam or commercial entries.
If the number appears on the sites of complaints or warnings, it is most likely an automated or advertising call.
Online telephone catalogs

There are web pages that function as modern “yellow pages”. These sites record numbers reported by other users, and also contain publicly accessible databases of companies.
Some useful pages include:
- Yellow pages of your country
- Lister
- Spamchalls
Just enter the number and check if other users report something about this. If you see a lot of negative comments, you already have an answer: it is better not to answer.
Look at your WhatsApp profile

This trick is simple and surprisingly useful. If the number you call belongs to a mobile phone and has a WhatsApp account, you can see part of your profile by adding it as a contact. Just follow these steps:
Step 1: Open the application Contacts And play the icon to add a new one.
Step 2: Add an unknown number to your agenda (do not worry, you can erase it later). Place a name that is easy to recognize.
Step 3: Open WhatsApp and start a new chat reproduced by a new message badge.
Step 4: In the search engine, write the name that you gave for contact. If a person has WhatsApp and did not limit the visibility of his profile, you can see their photo, status and user name.
You just could give yourself an idea of whether it is the one you know, or a completely stranger.
In the end …
When you get a call from a number that you do not know, do not rush back. It is better to do the following:
- Activate the antispam filter of your mobile phone.
- Use applications such as TrueCaller if you get a lot of unknown calls.
- Look for a number in Google.
- Check specialized sites in calls identification.
- If this is a mobile phone, check your WhatsApp profile.
Thus, you will avoid falling into fraud that irritates or just waste your time. In the end, know who is an unknown number, no longer requires a call back, just a little curiosity (and these tools are at hand).
