Moving from NIE to DNI does not update every health system together. At least three separate organisations hold your details: the Social Security Treasury/INSS, your regional health service and, if applicable, a private insurer. Correct each record and keep evidence.
Information reviewed on 27 August 2026. An Importass change does not replace the regional health-card or private-policy update. Channels and evidence vary by region and insurer.
Prepare
Have the new DNI, old NIE/TIE and support number, NIE–DNI concordance certificate if available, NUSS/NAF and a recent employment-history report, regional health card/CIP, any requested padrón certificate, policy number and insurer card. Keep Cl@ve, DNIe, a digital certificate or the registered phone available.
Do not request a second Social Security Number merely because you now have a DNI. Correct the linked identity document first and verify that the same NUSS/NAF and history remain.
1. Change NIE to DNI in Importass
Open Personal data in Importass and choose “Cambiar NIE por DNI”. The service says the NIE support number is required. Review DNI, names, birth date, nationality, address, phone and email before confirming.
Without electronic identification, Importass offers a request using personal details, a selfie and document photos. TGSS also provides scheduled video assistance through its telephone channel.
Save the receipt or reference. After processing, sign in with the DNI and download proof of NUSS, employment history and, optionally, contribution bases. If the history is empty, a different NUSS appears or records are duplicated, do not create another registration; report it to TGSS with both documents and receipts.
2. Check public healthcare entitlement
TGSS handles affiliation and contributions; INSS provides the service to check and document public-healthcare entitlement. Confirm that you appear as holder or beneficiary with correct details and download the certificate.
Review any dependants as well. The separate service for submitting a beneficiary’s identity document is not the route for changing your own NIE to DNI; use Importass for that.
3. Update the regional health card
Each autonomous community issues and manages its Individual Health Card. Regional CIP and national CIP-SNS link the health record; a document change should not create a new clinical history.
Use your regional service or the administrative desk at the assigned health centre. Bring DNI, current card, entitlement evidence and, when requested, concordance and padrón. Ask it to update the identity document, exact name, contact details, address, assigned centre, app access, appointments, clinical history and e-prescriptions.
Channels differ. Madrid accepts identification changes at the health centre or through an online procedure; the Canary Islands Health Service says personal-data changes must be made at the health centre. Check your region’s official instructions.
4. Prevent a duplicate health record
Check appointments, allergies, vaccines, reports, referrals and active medication. If the app shows an empty profile or the centre sees two records, ask admissions to review DNI, NIE, regional CIP and CIP-SNS and link them under its procedure.
Do not create several accounts as a test or send clinical records and identity documents through unapproved channels.
5. Notify a private insurer
A private policy is separate from the National Health System. Ask the insurer to rectify NIE to DNI for both the policyholder and each affected insured person. Use the secure channel in the contract and provide the policy number plus only the requested evidence.
Confirm names, birth date, contact details, address, bank account and insured people. Request written confirmation and an updated card or certificate. Check that policy number, seniority, waiting periods, approvals, reimbursements and direct debits remain intact. Do not cancel or replace the policy merely to update identification unless the insurer formally instructs you and the consequences are clear.
If inaccurate data remains, the AEPD right to rectification allows you to identify the incorrect detail, request the correction and provide supporting evidence.
Recommended order
- TGSS/Importass: identity and personal data.
- INSS: entitlement and beneficiaries.
- Regional service: card, CIP, app and prescriptions.
- Private insurer: policy, cards and approvals.
- Verify every system and archive receipts.
There is no single national deadline covering all these records. Update them promptly, especially before an appointment, prescription, work leave, trip, approval or reimbursement.
Common problems
- Importass still shows NIE: check the request and provide the old support number, DNI and concordance if requested.
- SMS access fails: update the TGSS phone first or use Cl@ve, DNIe or a certificate.
- Entitlement is correct but the card is old: take INSS evidence to the regional service.
- Health app is empty: ask for CIP and duplicate-record review, not an improvised new registration.
- Insurer changes the policy: request written confirmation that this is an identity rectification with contractual continuity.
Ready when
- Importass shows DNI while preserving NUSS and employment history.
- You can download healthcare-entitlement evidence.
- The regional card and digital services recognise DNI without losing history.
- Prescriptions, appointments, beneficiaries and clinicians remain linked.
- The insurer confirmed the correction without improper policy changes.
- You retain receipts and dates for every update.
