How can I check if my phone number has been lost

There was hacked data on more than 553 million Facebook users filtered online over the weekend, including the names, dates of birth, relationship status of a Facebook user, the city where they live, their place of work, and sometimes even email addresses . But the most sensitive data included in the filtering is possibly phone numbers, which are often used for two-factor authentication. And now there is a way to easily check if your phone number is leaked, at least if you live in the United States

The website News every day has a simple tool where you can enter your phone number and see if it appears in the filter. Gizmodo tested the tool against some actual Facebook leak data and found it to be accurate. For example, we tested Mark Zuckerberg’s phone number, which is included in the leak. It worked. (Suppose Zuck has already changed his phone number.)

All you have to do to check it is enter your phone number no hyphens or dots. You should also include the international country code at the beginning. For example, if you’re used to seeing your phone number on this form, 555-212-0000, you need to get rid of hyphens and add the digit “one” in front of it.

If you use the same false number above, the number you enter should be: 15552120000. If you include a variation other than the number string, the tool will falsely tell you that your number is not included in the filter. In fact, it could very well be.

Facebook hasn’t said much about the leak, accept that the information was hacked in 2019. The data was offered on hacking forums for a price two years ago, but what makes this weekend’s leak different is that the data has already been leaked for free. Everyone can find the 16 GB of data with a simple Google search.
