How do Caller ID Apps Work?

Caller identification during landline days meant being able to see who called you. Then the same technology moved to mobile devices. Network operators can not share subscriber information. Thus, subscribers only had access to the number and nothing more. But the advent of smartphones changed everything. Mobile devices have internet now. Thus, information could be shared among devices in seconds. Evolving network protocols further eased the process. Client server communication led to easier data collection. Apps on the phone now had access to your contact list. This contact list when uploaded to the server was an efficient source of information. The users further helped the apps identify themselves by creating accounts. The verified information from the accounts were then used as caller information.

Thus, every time you received a call from an unknown number, the app pulls the data about the number from its servers. This data collected from the users and everyone the user has called before was now available to you. Thus, it is easy to identify unknown callers within seconds after you receive the call. All these information is constantly collected and analyzed by companies. This allows the databases to remain accurate with latest information about phone numbers.

The constantly changing phone number have further made it difficult to identify unknown callers. Plus, cheaper plans allow even normal users to act as spammers to sell products and services. Thus, tagging the users by industry and other categorization features are necessary. This allows customers to understand who is calling and what their intention might b. Companies like Truecaller have taken the concept a notch further. They have integrated all necessary features in their app to understand users. This information is categorized and spam messages and calls are immediately barred. Similar models are adopted by a lot of companies to understand and deliver identification. Let’s review some of the commonly used Caller ID apps for Android.
