About 818.pw
818.pw is a free, no-sign-up directory for looking up US area codes and checking who has been calling from an unknown number.
What we do
818.pw helps you instantly identify the location, region, and time zone behind any US area code, and see community-submitted reports about calls from specific numbers. Every one of the 300+ area codes in the North American Numbering Plan (NANP) has its own page with coverage details, cities served, and caller feedback.
Where our data comes from
Area code, region, and time-zone information is compiled from public North American Numbering Plan Administration (NANPA) data and other publicly available telecom records. Caller reports are user-generated content submitted by visitors to help others recognize spam, scam, and robocall activity.
