After you receive your first Spanish DNI, request a NIE–DNI certificate of concordance if an authority, bank, employer or other organisation needs official proof that your former NIE and new DNI belong to the same person. The National Police issue the certificate through the relevant Immigration Office or police station.
Information reviewed on 22 September 2026. The Police provide the service at specific offices, but do not publish one national page promising identical documents, appointments and turnaround everywhere. Confirm your office’s instructions before paying or travelling.
Where this step fits after Spanish nationality
Follow the route in order: check the citizenship decision → complete the oath and Civil Registry registration → obtain your first DNI → request this certificate → update the organisations that still hold your NIE.
The certificate documents the identity link. It does not replace any of those stages or change every database automatically.
1. Decide whether you need it
It does not replace the DNI or update every database automatically. Request it when an organisation still holds your NIE, creates a duplicate profile or asks for formal evidence linking both identifiers.
Before booking another appointment, ask the unit issuing your first DNI whether it can provide the concordance or explain the local route. If an organisation accepts your DNI, old TIE and its own evidence of the change, the certificate may not be necessary for that particular update.
2. Find the right office
Use the official Police office finder and check that the office lists DNI–NIE concordance certificates among its services.
If your province requires an appointment, look for the Police option covering residence, non-residence or concordance certificates. The name and availability vary by province; a DNI or fingerprint appointment does not guarantee service for this certificate.
3. Confirm documents and fee
Prepare as a base:
- valid DNI and a copy;
- old TIE, EU registration certificate or another document showing the NIE, if retained;
- copies or receipts connecting the NIE to your records if the card was surrendered;
- appointment confirmation and contact details;
- sufficient authority if the office permits a representative.
The Police use form EX-15 for NIE and certificates. Confirm whether your office requires it for concordance and what reason to enter. The official 790 code 012 generator includes “certificates or reports issued at the applicant’s request” and calculates the current amount from the quantity. Do not reuse an old fee form, hard-code an old amount or guess a similar category.
4. Check the certificate
Before leaving, verify:
- full name;
- current DNI;
- former NIE;
- any personal-data variation that must be linked;
- date, issuing body and verification code or signature.
Ask for any error to be corrected immediately. Keep the original and a readable digital copy; provide copies unless an organisation needs to inspect the original.
5. Use it to update existing records
The certificate proves continuity of identity; it does not perform the updates for you. Start with public records and keep evidence:
- Tax Agency: the AEAT explicitly says a change from NIE to DNI must be reported with form 030 and evidence of the change.
- Social Security: Importass has a dedicated “Cambiar NIE por DNI” service. Afterwards, check that employment history, affiliation and benefits remain in one profile.
- DGT: check whether your driving and vehicle records now show the DNI. If not, follow the dedicated DGT NIE-to-DNI process.
- Employment and banking: ask each organisation to correct the identifier on your existing record. Use the bank, employer and payroll guide to preserve contracts and history.
- Other institutions: continue with healthcare, the padrón, education, insurers, utilities and other identity-verified services in the complete NIE-to-DNI checklist.
Do not open a new account when the organisation can correct the identifier on the existing one. Ask it to preserve history, transactions, contracts and obligations linked to the NIE.
6. Review digital identity
DNIe, Cl@ve and electronic certificates have separate lifecycles. Do not revoke an NIE-based certificate until you know how to complete open procedures. Test access with the new DNI, update registration where required and download outstanding receipts.
If one system still shows the NIE, do not assume every record is wrong. Databases may synchronise at different times. Provide the concordance certificate and request an identity-data correction, not a duplicate registration.
Local and organisational differences
The competent office, appointment, extra documents, applicable fee and turnaround can vary. Each organisation may also accept different evidence for its update. Record the procedure name, date, receipt and answer received.
Ready when
- You have a valid DNI and readable evidence of the former NIE.
- The Police confirmed the applicable office, appointment, form and fee.
- The certificate correctly links NIE, DNI and personal details.
- AEAT and Social Security show the DNI without duplicating your history.
- Priority organisations have confirmed the change.
- You retain a list of pending updates and evidence for each completed one.
Next step
Use the complete checklist of organisations where you should change NIE to DNI and record the outcome of each update.
