DOI vs Handle: What Is the Difference?
A DOI is built on the Handle System, not a separate technology. How resolution, governance (IDF vs DONA/CNRI), and metadata requirements differ.

How do DOI, Handle compare side by side?
The table below compares DOI, Handle across 9 procurement-relevant dimensions, from established through cost.
Side-by-side comparison
| Dimension | DOI | Handle |
|---|---|---|
| Established | 1998 | 1994 |
| Governing body | International DOI Foundation (IDF) | DONA Foundation (global technical governance since 2015); CNRI is an accredited Multi-Primary Administrator |
| Relationship | A governed, metadata-rich identifier scheme implemented using Handle | The underlying general-purpose resolution technology; DOI is one application of it |
| Format example | 10.1234/abc.123 | 20.500.12345/abc.123 |
| Resolver | https://doi.org/... (a proxy over the Handle System) | https://hdl.handle.net/... (direct) |
| Who can mint one | Only accredited DOI Registration Agencies (Crossref, DataCite, and others) | Any institution that registers a Handle prefix |
| Required metadata | Mandatory schema per Registration Agency (Crossref schema, DataCite Metadata Schema) | None required — free-form |
| Typical use | Journal articles, datasets, software releases intended for formal citation | Institutional repositories, ETD systems, internal archives |
| Cost | Per-DOI registration/membership fee paid by the depositing organisation | Free once a Handle prefix is registered |
Common questions
Common questions about DOI vs Handle
Is a DOI a type of Handle?
+
Yes — technically, every DOI is implemented as a Handle and resolves through the same underlying Handle System infrastructure. The DOI layer adds mandatory metadata and Registration Agency governance on top.
Why would an institution use a bare Handle instead of a DOI?
+
Mainly cost and overhead: minting a Handle directly requires only a registered prefix, with no per-identifier fee and no mandatory metadata schema, unlike going through an accredited DOI Registration Agency.
Do researchers pay for DOIs?
+
No — the depositing organisation (publisher, repository, or institution) pays the Registration Agency's membership and per-DOI fees, not the individual researcher.
