About NumberCheck

NumberCheck is a free, community-powered directory that helps you find out who's behind an unknown phone call before you pick up.

How it works

Anyone can search a phone number and see what other people reported about it. If you recognize a number as a scam, spam, or a legitimate business, you can add your own review to help others.

Built by the community

NumberCheck doesn't buy or sell phone data. Every report on this site was submitted by someone who actually received a call from that number.
