Can anyone search DNI by name?
Not necessarily. RENIEC's information-supply services are available to certain entities, including public organizations, notaries, and qualifying private legal entities, subject to requirements and evaluation. The stated purpose includes identity validation while respecting personal privacy.
Therefore, DNI por Nombre should not be interpreted as an unrestricted public database. A person looking for their own information may have access to specific citizen services, while an organization performing identity verification may have a different authorized level of access. The type of information available can therefore depend on who is making the request and why.
