Our Data

ReversePhone aggregates telecommunications records, public directories, and government data sources to help you identify unknown callers and look up phone number history. Our mission is to make caller identification accessible and easy for everyone.

What our data includes

• Carrier and telecommunications provider records
• Reverse phone directory data
• Name, address, and associated public records linked to phone numbers
• Do Not Call registry data
• Community-reported spam and robocall data from verified sources

How we maintain data quality

ReversePhone has spent over a decade curating data from dozens of telecommunications and public records providers, giving us access to millions of phone numbers and billions of associated data points. Phone number data is inherently dynamic. Numbers are reassigned, ported between carriers, and linked to new owners over time. We aggregate from multiple sources and update continuously to help maximize accuracy. Coverage and recency vary by carrier, number type, and reporting history.

A note on accuracy

Not all phone numbers have associated records, and some information may reflect previous owners of a reassigned number. We recommend using ReversePhone reports as a starting point for identifying unknown callers rather than as definitive identification.
