News circulating about Pavel Durov's phone number starting with +999 is based on a test number. This number was previously accessible on Telegram's test servers and reserved exclusively for Telegram developers on production servers. Information regarding this test number is readily available online. Currently, such test numbers are deactivated on test servers, and their use is restricted to Telegram developers. Therefore, it is not possible to sign up for Telegram with this number. It's important to note that these are not new "anonymous" phone numbers, unlike the +888 series. The reason for Durov's choice of a test number remains unclear, though personal preference may be a factor. @unofficial
