Despite using 2FA and listing my number on my profile - albeit restricted to "just me", I don't appear in the data. It's not as simple as they just having a record of it somewhere.
I'm in the same situation and very surprised. I've sat here wondering if I'm entering my numbers wrong, or if I'm really not in it. I've read the blog post and I'm entering the 1 in front of my 10 digits, because I'm in the USA.
My wife's number isn't in there, either. I'm just really surprised, because I checked facebook the other day and it said I was searchable by email and phone number.
I even searched my email address, and a lot of other breaches show, but not Facebook.
Likewise, it seems there's more nuance to this leak. I checked the data out and a large number of my contacts have correct numbers in it. At the same time, numerous people don't appear in it, even if they do have a phone number on their profile.
