Thanks David! Was going to download/parse the data myself to see if I had been impacted so appreciate you making this tool.

Country versions for Australia and NL were appreciated.

Really helpful - thank you!
brendanfalk on HNI made a version for NL users, but based on first name/last name (returning the last three digits of their phone number): https://jstsch.com/facebook

Objections
Entering a phone number risks privacy, since it adds IP and metadata to the operator's data.

David may very well be a trustworthy individual, but any time you voluntarily transmit your phone number online (to Facebook, or otherwise...), you are putting your own personal…
Hydraulix989 on HNIf you are in the breach, the site operator already has your name. And now they will also have your IP address. Yes I realize not all users will enter a phone number that is…

ashkankiani on HNJust release a CSV containing just the numbers as a zstd compressed file. We can search it ourselves.

Questions
Where to find the leaked dataset?
From 2 comments
Where can I find the data set? I want to grep for my friends and family and see which data is leaked.
alephnan on HNWhere would one find the data though?
vvatermelone on HN
Does the tool store submitted numbers?

Alternatives named
Downloading the leaked dataset and grepping it locally.

Or you could just download the data yourself and grep it. No need to submit your phone number to yet another website.
