How long has this service been running and who is it for?
The service was created in 2011 in the Czech Republic. It is an online forum where the users can share their experience with phone numbers, both annoying (mostly telemarketing, surveys) and useful (e.g. couriers, offices)..
Since the beginning, the service has been received very well, which led to localization into more languages. Nowadays, the forum exists in more than 20 languages and 34 countries throughout the world.
The service is intended for anyone who wants to identify the owner of an unknown phone number. The creators of the forum have also recently created the mobile app Call Insider for Android phones. This app, which is connected to the database of the website phonenumbers.ie, also allows users to automatically block telemarketing numbers.
Spam calls — or "scam calls" as they're also known — have become an infuriating part of life. By now, most people are well acquainted with fraudsters trying to dupe you out of your cash by impersonating government officials or Amazon employees.
Mobile phone users are unlikely to get a respite from the menace of pesky commercial calls and text messages anytime soon as the majority of these come from unregistered telemarketers (UTMs) using personal mobile numbers that are almost impossible to monitor or bar, say senior telco executives.
