TraceCheck is an online lookup service that helps people identify callers, verify online contacts, and explore information associated with phone numbers, email addresses, photos, and vehicle identification numbers. Its tools can surface publicly available details such as names, possible addresses, family connections, professional information, social and dating profiles, usernames, carrier data, and vehicle history. Reports may also include public spam or fraud complaints, web mentions, and exposure in known data-breach indexes; the information available varies by search and source.

TraceCheck says it compiles records from public and commercially licensed sources, including government registries, directories, public profiles, carrier data, and web archives. It does not provide live location tracking and states that it does not access private databases or collect device data. The service is intended for personal informational use and is not a consumer reporting agency; its results cannot be used for employment, housing, credit, or insurance decisions covered by the Fair Credit Reporting Act. One subscription includes access to its lookup tools, with a paid trial and recurring billing.
