We already explained at the time how to identify and know whose an unknown phone number is. Now, we will review the best web pages to know who is calling by phone; in this way, you can easily identify spam numbers.

One of the most popular platforms to find out who calls you for free is ListaSpam.

This website has become one of the most used resources for discovering who the calling number belongs to and thus knowing if it is a spam call.

It is possible to use ListaSpam to find out who is calling you both in Spain and Latin America, and thanks to users’ participation, more and more telephone numbers are stored in its database. Best of all, you don’t need to register to look up phone numbers.


Another famous platform to identify phone numbers, which also has its own mobile app. With TrueCaller, you can search for phone numbers and identify who they belong to, thanks to its integrated search engine.

If you are using the Truecaller website, you will need to create an account to search for phone numbers.

One of its advantages is having an international database so that it is possible to identify the owners of unknown telephone numbers, regardless of the country from which the call comes.


Answer or not

A famous alternative to ListaSpam is to respond or not. It is a very easy-to-use service, with a search engine that allows you to find phone numbers and the companies associated with them.

In this way, the rest of the users can mark the telephone numbers as a neutral, scam, or useful so that other people can know if the telephone numbers that call us are safe, or if, on the contrary, it could be a call of spam.

Remote control

At the time, Infotelefónica was one of the most famous websites to find out whose phone number is. Since its disappearance, Teledigo is the service that has somehow taken its place.

It is a general source of information that uses information obtained from the CNMC to offer data such as the identity behind unknown telephone numbers.

It is a page as easy to use as the others: simply access from the browser on your mobile or computer, enter the phone number in the search engine, and you will see all the information associated with the number, as well as the comments of the rest of the members. You do not need to register to use it, and it is completely free.

Who has called?

Its creators define this platform as a database of web page visitors with phone numbers of unwanted or unknown callers.

Thanks to it, it is possible to identify marketing companies, surveys, or contests, as well as false calls or telephone spam.

In this phone book, you can see the comments of other people about the phone numbers and their owners. It’s free, and you don’t need to register.

Who calls me?

Despite having a name very similar to the previous option, who calls me? It is a different tool. You have to access the page and, without having to log in or register, you will be able to look up phone numbers and find out who the number that called you belongs to.


Its name says it all: with TelephoneSpam, you can discover who is calling you and if the number belongs to a company that in the past has been associated with spam techniques or telephone abuse.

It is a perfect option if you think you have received a suspicious call, as it has a database made up of thousands of numbers and user comments, which indicate whether the calls may be dangerous.



Some say that Tellows is the best alternative to Truecaller.

It is a web page – which also has its own app – from which you can search for phone numbers from all over the world and find out who they belong to.

Tellows allows us to know both the company or person owned by the telephone number, as well as information about their prefix if the caller is from Movistar, Vodafone, Orange, or other operators and the general assessment based on the reports generated by the rest of the people.

The platform can be used for free, although you must create an account to take advantage of its functions.
