Number database 101: Top three reasons why you should update it!

1. Number tag! So phone numbers are constantly changing?

    Phone numbers associated with scammers, telemarketing, and company organizations, etc., are continuously changing. In particular, fraud calls often use a strategy of using IP Internet phones to quickly obtain new numbers or falsify numbers to pretend to be a business’ number. After they are reported, they can just change their number again.

    Since numbers change so rapidly, Whoscall has to stay up to speed, importing new numbers into the database weekly and reminding you to open the app and update it!

    2. Integrating 1.6 billion numbers and sending them to your phone

      Whoscall has a database of 1.6 billion phone numbers from across the globe. If each call is added to the app database, it would take up tons of storage on users’ phones. Because of this, Whoscall integrates a local list of highly active numbers and the latest high-risk numbers, including scams, high-frequency telemarketing, and harassing calls and imports this list to the number database. Users just need to update their app manually or automatically each week to be fully protected by Whoscall.

      3. What will happen if I don’t update weekly?

        Numbers change rapidly. If the database isn’t continuously updated, the latest active numbers may not be recognized, resulting in a decrease in recognition rate. According to Whoscall statistics, the Thailand number database is updated with an average of more than 80,000 numbers* every week. By adding these numbers to your Whoscall app, you can greatly enhance number recognition rate! In addition, the number database will continue to update its high-risk numbers to help keep users safe from all kinds of nasty scams and protect the safety of your calls.

        *This number is based on weekly statistics, the actual number may vary week to week and according to differences in iOS and Android systems.

        User FAQ’s! Your magic genie is here with answers

        Q: Why does the Android version of the app show “the number database is outdated; the number cannot be recognized” when getting a phone call?
        This is because your number database is out of date. Please update it to ensure the caller ID function works properly.

        Q: Why does the Android version of the number database expire? Can’t I just download all the numbers at once?
        As mentioned above, if all 1.6 billion numbers were imported into the app database at once, it would take up a lot of space on your phone. As scammers are getting more creative and replacing phone numbers at higher rates, it is important to update the Whoscall number database weekly, so that the information stays current. We recommend upgrading to Whoscall Premium and use the auto update function so that you have the best number-identification experience!

        Q: Since I can’t download all the numbers at once, can I just search numbers online?
        The environment in which we answer the phone may cause differences in mobile network speed, which in turn affects the results of online queries. The number database allows users to identify results even with no internet connection. Therefore, although Whoscall has an online search function, we recommend users download the latest number database regularly to ensure better identification potential.

        The more up-to-date the database is, the more powerful number recognition is!
