i found my prefix number but when entered i get this error message: “Those credentials were not accepted by the service. Please check your credentials and try again.”
Thanks for following up. Unfortunately, the VuePoint IDS Inc. (DOI prefix 10.57204) account associated with the CRO (Clinical & Refractive Optometry) Journal (ISSN 28167988) is currently inactive, so that’s why you are receiving the errors that you have reported when attempting new registrations for this journal and prefix.
You can contact us at member@crossref.org or follow up on Zendesk ticket 531941 where you were discussing this with Collin on our membership team back in February 2025.
