You need to be a member of the Crossref organization in order to get a DOI prefix so you can create Crossref DOIs and deposit content. There's an annual fee for membership, which varies depending on your publishing revenue. As a guide, the lowest tier is $275 per year for organisations with publishing revenue lower than $1 million. If you don't have revenue for your publishing, we look at publishing expenditure. The fees are the same for commercial and not-for-profit publishers.
As a member, you have obligations to your fellow members and the wider scholarly community - these include keeping the metadata associated with your content up-to-date, making sure that you use DOIs in your article references, and displaying your DOIs on the landing page for your content.

Once you become a member, we provide you with a DOI prefix. You then use this prefix to create full DOIs for your journals and articles, and register them with us by providing the url for the content and a lot of other metadata. This can be done via a web form, or by submitting XML.
There is a one-off fee for every DOI Content Registration . These fees vary depending on the type of content and whether it's current or backlist. But as a guide, the costs to deposit a current journal article is $1. These are usually billed quarterly in arrears.
