Rut y Nombre is an online information service focused on helping people in Chile look up individuals and businesses using a RUT, name, surname, or company legal name. Its search tool is designed to make it easier to find available identity-related references, check a name against a known RUT, distinguish between people with similar names, or identify the legal name associated with a business. The site also explains how to enter search details, interpret possible matches, and address common issues such as incomplete names or an incorrect verification digit.

Alongside its lookup function, Rut y Nombre offers practical guidance on Chilean identifiers, responsible use of personal information, and the limits of search results. It emphasizes that matches are preliminary references, not official certification or proof of current identity, address, legal authority, or financial standing. For formal matters, the service advises users to confirm information with relevant institutions, including the tax authority or Civil Registry.
