Users don’t technically need to provide their own personal number, but they must have access to whatever device they text an initial verification code to. This number is then visible to contacts and can not be hidden.

When joining WhatsApp, users need to provide a phone number during the account creation process. This means that WhatsApp will display a different number, but it was not made by or for the app. If a WhatsApp user on iOS or Android changes their mobile telephone number, the application will not automatically update their contact details. No, WhatsApp does not give users a new phone number. Does WhatsApp give you a new mobile number? So, does WhatsApp give you a phone number for signing up? Here’s the need-to-know on how contact numbers integrate with the WhatsApp application on iOS and Android. Understandably, this can be a cause of confusion. Some users have noticed that their profile displays a different telephone number to their current mobile number, though.

“Today, your mobile number is linked to your Bitcoin wallets, Adhaar, bank accounts, UPI, credit cards… an attacker to perform SIM card swapping and cloning attacks is another possibility,” he said.WhatsApp is a great way to keep in touch with friends and family, especially with the situation in 2021. Jayaram, however, believes the firm should take the disclosure more seriously, due to the scope of attacks the issue could facilitate. “All WhatsApp users, including businesses, can block unwanted messages with the tap of a button.” “While we appreciate this researcher’s report and value the time he took to share it with us, it did not qualify for a bounty since it merely contained a search engine index of URLs that WhatsApp users chose to make public,” said a WhatsApp spokesperson. The application was dismissed, however, on the grounds that WhatsApp users have full oversight of the information attached to their profile that is made publicly available. Having made the discovery on May 23, Jayaram subsequently reported the issue to WhatsApp owner Facebook through its bug-bounty scheme. Clicking through to the web page does not uncover the user’s full name, but does reveal their WhatsApp profile picture. Scouring the domain via Google searches, Jayaram reportedly uncovered 300,000 WhatsApp numbers made public via this mechanism.
