DOI Foundation - Digital Object Identifier System
DOI.org is operated by the DOI Foundation, a not-for-profit organization that governs the Digital Object Identifier (DOI) system. A DOI is a persistent digital identifier for any object—physical, digital, or abstract—that remains stable even when the object's location changes. The infrastructure is maintained by the Corporation for National Research Initiatives (CNRI).
The DOI system serves registration agencies across multiple sectors including scholarly communications, research data, entertainment, standards bodies, and cultural heritage. When formatted as links (e.g., https://doi.org/10.xxxxx), DOIs redirect to current information about identified objects through the proxy resolver. In December 2025, the system reached 3 billion proxy resolutions, handling approximately 1,146 resolutions per second.
