UPF is a Crossref member and registers DOIs under its own prefix. Probed 2026-09-01: GET https://api.crossref.org/members/14960 returns HTTP 200 with primary-name "Universitat Pompeu Fabra", prefixes ["10.31009"] and counts current-dois 563, backfile-dois 1030, total-dois 1593; GET https://api.crossref.org/prefixes/10.31009 returns HTTP 200 resolving the prefix back to member 14960. This is a fact about UPF, not a misattribution — the Crossref API contract is Crossref's and is not saved here. UPF has no DataCite client of its own: a query of api.datacite.org/clients for "pompeu fabra" returns zero, while 2,733 DataCite DOIs carry a UPF ROR affiliation registered by other clients.
