Deleting an ORCID account in the literal sense is not possible — ORCID only offers “deactivation,” which permanently erases personal information (name, biography, employment, works) but keeps the bare 16-digit ORCID iD in the registry so it can never be reassigned. For most researchers the underlying concern — unwanted public exposure, not the identifier itself — is better solved with a two-minute visibility-settings change than with account deactivation.
An ORCID iD is a free, persistent identifier issued by ORCID, a non-profit organisation, to disambiguate researchers and link their scholarly outputs, employment, and funding records across publishers, funders, and institutional systems. Researchers searching for how to delete orcid account most often turn out to want one of three different things: hide their record from public view, merge a duplicate iD, or genuinely close the account — and each has a different, correct fix.

Can you actually delete an ORCID account?
No. ORCID’s own account-settings interface has no “delete” function — the only self-service option is “Deactivate your ORCID account,” found under Account actions in account settings. Deactivation removes personal data from public view and from ORCID’s active record, but the iD itself is not destroyed.
This design choice is deliberate. ORCID retains every deactivated iD permanently to prevent the same 16-digit number ever being reissued to a different person, which would corrupt the disambiguation function the identifier exists to provide — a linked grant, dataset, or peer-review credit pointing to the wrong individual.
What data is removed versus retained on deactivation
According to ORCID’s own support documentation, deactivating an account deletes essentially all personal content from the record but keeps two things: the iD number and a masked form of the email address used to open it.
| Data element | What happens on deactivation |
|---|---|
| Name, biography, employment, education, works | Permanently deleted from the record |
| Links to publications, grants, and peer-review records | Removed within the ORCID registry |
| Visible email address | Deleted from public view |
| Underlying email address | Retained as a cryptographically-masked (hashed) value, not visible to ORCID staff or the public |
| The 16-digit ORCID iD itself | Retained permanently in the registry; blocked from reassignment |
The deactivation is confirmed by email — sent from [email protected] — and only takes effect once the account holder clicks the confirmation link, a safeguard against unauthorised or accidental deactivation.
Deactivation vs visibility settings: which do you need?
Deactivating an account is usually the wrong tool for the job. ORCID’s visibility settings let a researcher restrict who sees each piece of data — Everyone, Trusted Parties, or Only Me — without deleting anything or breaking links that publishers, funders, and CRIS systems rely on. That default can be set once for all future entries and adjusted item-by-item for existing ones.
| Action | Effect on data | Effect on the iD | Reversible? | Best for |
|---|---|---|---|---|
| Change visibility settings | Hides selected data from public view; institutional/funder systems using trusted-party access still see it | Unaffected | Yes, instantly | Privacy concerns while staying discoverable to legitimate systems |
| Deactivate account | Personal data permanently deleted; links to works removed | Retained, blocked from reassignment | Yes, via reactivation, until email is fully removed | Genuinely leaving the research system |
| Merge duplicate iDs | Data consolidated onto one record; the other iD is not deleted but stops being used | Both iDs persist; one becomes primary | No — merges are not undone | Accidentally registering more than once |
| Request full email removal | Same as deactivation, plus the masked email is purged | Retained, blocked from reassignment | No — reactivation becomes impossible | A firm, permanent exit with no future return |
Because deactivation severs links to existing works and cannot be quietly undone without re-entering data, ORCID and most institutional research-support offices recommend visibility changes as the default response to a privacy request, reserving deactivation for cases where the researcher is genuinely stepping away from having any discoverable research identity.
How to deactivate an ORCID account, step by step
For the minority of cases where deactivation is genuinely the right choice, the process is short:
- Sign in and go to account settings, then scroll to the Account actions section.
- Select Deactivate your ORCID account.
- Read the on-screen summary of what will be deleted and what will be retained.
- Click the red Deactivate ORCID account button to trigger the confirmation email.
- Open the email from [email protected] and click the confirmation link — deactivation only completes at this step.
Registering an ORCID iD is, and always has been, free for individual researchers — ORCID is funded by paying member organisations (universities, publishers, funders), not by researcher fees, so cost is never a reason to deactivate rather than simply set up or reuse an account correctly.
Duplicate iDs, reactivation, and full email removal
Before assuming a new iD is needed, check whether one already exists — the public ORCID registry can be searched by name, avoiding an accidental duplicate.
If a duplicate has already been created, ORCID explicitly advises against deactivating either account. Deactivation does not delete the surplus iD or merge its history — it only strips personal data from whichever record is closed. The correct fix is ORCID’s duplicate-record removal process, which merges the two records so publication and funding links consolidate onto a single, primary iD.
Deactivated accounts can be reactivated at any time by entering the original email address on the ORCID sign-in screen, which triggers a reactivation link. Reactivation does not restore deleted data automatically — works and profile details must be re-added, either manually or via the same connections (CrossRef auto-update, institutional CRIS sync) that populated the record originally. A new account cannot use the same email address unless the old one is reactivated first, or unless the masked email has been separately removed, which permanently forecloses reactivation.
Answer-first Q&A
Can I delete my ORCID account?
Not literally. ORCID offers only “deactivation,” which permanently deletes personal information — name, biography, employment, works — from the record but keeps the bare ORCID iD in the registry indefinitely to stop it being reassigned to another researcher.
Is disabling an account the same as deleting it?
No. Deactivating removes visible personal data and unlinks works, but the account can still be reactivated later using the original email address. Only a separate, additional request to fully remove the masked email address makes the closure permanent and irreversible.
How do I make my ORCID record private instead of deleting it?
Open account settings and use the Visibility tab to set each data field, or a future default, to Everyone, Trusted Parties, or Only Me. This restricts public visibility instantly without deleting data or breaking links used by funders, publishers, or institutional systems.
I have two ORCID iDs — what should I do?
Do not deactivate either one. Use ORCID’s duplicate-record removal process to merge the two accounts, which consolidates works and funding links onto a single primary iD rather than deleting either record’s history.
Why this matters for institutions and research administrators
ORCID iDs are embedded in grant-management systems, publisher submission workflows, and institutional CRIS platforms because the identifier is expected to stay stable over a researcher’s whole career. A deactivated-then-reactivated account with data gaps, or an unnecessary duplicate iD, breaks automated matching between a researcher and their prior grants, datasets, and peer-review record — the exact failure mode the identifier exists to prevent.
Research offices should default to recommending a visibility-settings change for privacy concerns and the duplicate-merge process for accidental multiple registrations, reserving deactivation guidance for researchers unambiguously and permanently leaving the research system.
These identifier-integrity questions sit within the broader discipline of research administration infrastructure, where persistent identifiers, grant systems, and compliance records depend on consistent, non-duplicated researcher records. For definitions of related terms, see the CASRAI research administration dictionary.
The practical takeaway
Very few researchers actually need to delete an ORCID account, because ORCID does not offer true deletion in the first place — only deactivation, which is deliberately hard to fully reverse and strips data that took time to build. Before deactivating, check whether a visibility-settings change or a duplicate-merge solves the actual problem; both preserve the account’s value while addressing the privacy or duplication concern that usually prompts the search for a delete option.
