About CallerCheck
CallerCheck is a UK-focused phone-number lookup and community call-reporting service, available through a website and an iPhone app. Users can search UK numbers to review community reports, risk scores, reported call types, and available location or network information, then submit their own reports about suspicious, unwanted, or legitimate calls. Number pages combine report histories and summaries, while the site also offers a UK area-code directory, recent reports, scam alerts, and practical guides to common phone scams. The iPhone app can label reported spam or scam numbers when they call and in the recent-calls list; an optional paid CallerCheck PRO subscription adds features such as automatic call blocking, a personal block list, and alerts for watched numbers. Core number searches and reports are free, and users can access the service without creating an account.
