Apps to identify unknown numbers

Additionally, there are a series of applications that can help people identify a cell phone number but, as Xataka says, it is not the most advisable since they can obtain important information such as numbers: “These applications work by collecting contacts, and will request access to calls and SMS.”

Despite that, in a more detailed report, the outlet pointed to popular ‘apps’ that show who the caller is, using “up-to-date databases”; some of them are ‘Truecaller’, ‘Whoscall’, ‘Who’s calling’ or also ‘CallApp’.

Another way that is applied by several people is to verify if the person who made the call has a WhatsApp account and see if they have a photo or a username in their profile.
