NumBuster is the go-to database for anyone who wants to check unknown numbers. It’ll dig up info even on scammers — never doubt it!

Great app. It often saves the day — thank you for creating it! If there’s no info or just 1–2 results, it’s probably a new number or just a normal person. Scammer numbers always show tons of reports.
