Truecaller
Caller-ID and reverse phone lookup service that shows a name and spam label for a phone number.
Truecaller is a caller identification and reverse phone lookup service that displays the name associated with a phone number. It also provides spam labels to help users identify potentially unwanted calls. This tool is commonly used to check what name and spam label a phone number carries.
Dual-use tool. This is capable of legitimate research (journalism, security, due diligence) and of harassment or stalking. Listing it here is not an endorsement of either use.
Privacy note. Your name and number can appear in Truecaller's caller-ID database even if you never used the app. Truecaller publishes an unlisting page (truecaller.com/unlisting) where anyone can ask for their number to be excluded from name search.
