How are DOI numbers assigned?

DOI numbers are assigned by authorized Registration Agencies (like CrossRef or DataCite) to publishers or institutions, consisting of a prefix (identifying the agency/organization) and a unique suffix (assigned by the publisher for the specific item), allowing for persistent, unique identification of digital content, even if its location changes. The process involves registering the object (article, dataset, etc.) with an agency, which assigns the prefix, and then the publisher creates a unique suffix, often automatically generated.
