Crossref's ORCID Auto Update allows publishers to deposit an author's ORCID identifier with their article metadata. Crossref will then request permission from the author to post their works to their ORCID record. Once permission is granted, Crossref will automatically post current and past works to the author's ORCID record. As of now, Crossref has sent over 481,000 requests, with over 100,000 authorizations and nearly 12,000 denials, adding over 136,000 works to ORCID records.
