Investigator Use

ThatsThem (thatsthem.com) is a free US people search engine that provides name, address, phone number, and email address lookup by allowing investigators to search in both directions — finding a person's contact information from their name, or identifying a person from a specific contact identifier.


For OSINT investigators, ThatsThem's bidirectional search capability and free access without registration make it an efficient quick-lookup tool for US person research. The reverse lookup functions — finding a name from a phone number, email address, or physical address — are particularly valuable for connecting known contact information back to an individual identity.


Phone number reverse lookup through ThatsThem quickly identifies the registered name and location associated with a US phone number. When a phone number appears in investigation materials without clear ownership, ThatsThem can immediately provide the associated name as an investigation lead.


Email address reverse lookup connects an email to associated names and locations, useful for identifying who is behind an email address encountered during investigation.


IP address lookup is available through ThatsThem, associating IP addresses with geographic location and ISP information for the ISP serving that address — a supplementary quick-reference for IP investigation.


ThatsThem aggregates from public records databases and may not have complete or current information for all individuals. Free access means the service provides sufficient data for initial investigation without requiring subscription — useful as a first-pass quick lookup before committing to paid services.


The free, no-registration model makes ThatsThem suitable for quick investigative lookups that don't warrant the overhead of commercial database subscriptions, particularly for initial subject identification tasks.


Document all ThatsThem searches with queried identifiers, results returned, and timestamps for investigation records.
