Tellows (stylised as tellows) is an online platform[disambiguation needed] to rate the trustworthiness of unknown phone numbers and to share information about unknown callers. The mobile application of tellows, with the features of Caller ID and blocking unwanted calls, are available for Android and iOS.
History[edit]
Tellows was first developed by Stefan Rick, Christian Anton and Denis Thomas in Bennewitz, Germany, in 2010.[1] The first domain, tellows.de, was published on the 6th of April 2010 with the purpose of sharing information of phone numbers and protecting users from unwanted and dubious calls. Due to the high demand on phone number information, especially in Europe, tellows expanded its service to other European countries, including Italy, France, Spain and the UK in the following years.[2]
In 2011, tellows launched a caller identification app for Android. The application identifies incoming calls and shows if the number can be trusted or not. [3]
Focusing on landline solutions, tellows built a hardware device to block unwanted calls within the home phone system. In 2014, the call blocker was released in Germany, Austria and Switzerland.[4]
Features and functionality[edit]
Tellows functions as a caller ID service for its users to identify and block phone numbers that have been reported as dangerous numbers by its community. The database contains phone numbers, information about the numbers, and user generated ratings for every reported phone number. Users are able to rate phone numbers and select the type of call within the rating.[5]
This data is compiled and, via an algorithm, a trustworthiness rating is generated for each number and is displayed as the tellows score. The score has a scale between 1 and 9, with 1 indicating a very trustworthy phone number and 9 being a very dangerous phone number.[6] The users are also able to select the given type of calls for every number that calls them. There are currently ten categories of the caller types: unknown, trustworthy number, sweepstakes, debt collection company, aggressive advertising, survey, harassment call, cost trap, telemarketing, and ping call.[7]
Tellows mobile app is currently supported on Android and iPhone. The application is used for real-time identification and automatic call blocking. In the application, users can rate unknown phone numbers and flag up spam, scam or unwanted calls that the users have received.[8]
Tellows cooperates with telephone and technology companies as well as developers.[9] The phone database is used for the development of products with a built-in caller identification. Besides mobile applications, the database has been integrated into landline phones and PBX. The database has also been used by different sources, e.g. BBC news to analyze the data of telephone numbers or information about certain phone scam topics.[10]
