Helping people decide which calls to answer
Who Called This? is a community website that helps people identify unknown callers and avoid spam calls, robocalls and scams.
Telemarketing calls, robocalls and scam calls are part of everyday life. We built Who Called This? so people in the US can look up an unknown number and share what happened when it called them.
People share what happened when a number called them
We keep track of US phone numbers and how often people look them up
We help you spot scams and spam calls before you answer
The website is run by the operator named on the Contact page. We are responsible for running and developing the platform and for handling complaints about content.
Number pages are built from two sources: activity data (how often and when a number's page is viewed, statistics for its range) and reports and ratings added by users. We count every page view without filtering out automated traffic, so treat the figures as a rough measure of interest in a number. We do not invent authors - all editorial content is published by our editorial team.
Reports come from users and are published without prior moderation. Unlawful, abusive or defamatory content, other people's personal information and spam are not allowed. We remove such content when it is reported to us or when we find it.
If a report is untrue, unlawful or infringes your rights, email contact@whocalledthis.com. We usually review complaints within 72 hours on business days and remove content that breaks the rules.
