Frequently asked questions

How do I get a DOI?

DOIs are obtained through a DOI Registration Agency (RA), which collects metadata, assigns DOI names and offers services such as reference linking or metadata lookup. You do not need to be a member of the DOI Foundation to work with an RA.

How much does it cost to get a DOI?

The cost of registering new DOI names depends on the services purchased, as each Registration Agency is free to offer its own business model, so you should contact an RA to discuss options. Existing DOI names are, and always will be, free to resolve.

How do I resolve a DOI name?

Prefacing a DOI with doi.org/ turns it into an actionable link, for example https://doi.org/10.1000/182, which the proxy server redirects to the object's current location. The proxy service supports HTTPS (preferred) and HTTP, is accessible over IPv6 and supports DNSSEC.
