Your phone number is the most dangerous piece of information in your digital footprint, because it cannot be recycled. Numbers cannot be changed, once leaked it stays leaked. And most people have no idea theirs may be sitting inside a tweet from a decade ago.

How the check finds it

The logic is more honest than you might expect. Every tweet is split into segments and run through two matching passes:

  • Format recognition: international prefixes, number patterns, and common variants including spaces, hyphens and parentheses.
  • Context matching: phrases like "call me", "text me" next to digit sequences, which catches non-standard formatting.

Results are merged, deduplicated, and ranked by risk level.

How false positives are handled

Not every digit string is a phone number. Order IDs, account IDs, landline numbers all get caught initially. Three filters clean it up:

  1. Exclude strings that are clearly too short or too long.
  2. Cross-validate area codes and number ranges against a reference table.
  3. List remaining candidates in a "pending review" queue for you to confirm, instead of declaring them leaks outright.

So the report says "N suspected, M confirmed" rather than scaring you with everything it found.

What to do once a number is found

  1. Delete the confirmed tweets first. Phone numbers carry the highest point deduction; removing one is worth more than deleting a hundred harmless posts.
  2. Check your bio and pinned tweets for the same number. The scan only covers tweet text.
  3. Only consider changing your number if you have been harassed or doxxed. For most people, deleting the tweets is enough.
  4. Rescan afterwards to confirm clean.
