Digital NIE: what exists and what doesn't
There is no 'digital NIE' document in Spanish law. What exists: your NIE number working inside Spanish digital systems — Cl@ve login, the tax portal, and the FNMT digital certificate.
TL;DR
- No standalone “digital NIE” document exists — the number is what matters.
- Your NIE works in Cl@ve, the AEAT tax portal and notarial e-signature.
- The FNMT digital certificate is issued against your NIE — that is the real “digital NIE”.
- Services selling a “digital NIE” as a separate product are selling the same number.
Where your NIE works digitally
| System | What you do with the NIE |
|---|---|
| Cl@ve | Login identity for Spanish public services |
| AEAT (tax portal) | File Modelo 100/210 and any tax — NIF field takes the NIE |
| FNMT digital certificate | Certificate issued against your NIE for e-signature |
| Notarial e-deeds | Remote signature with your NIE + digital certificate |
Getting the FNMT digital certificate
The closest thing to a “digital NIE”: the FNMT issues a personal digital certificate against your NIE, enabling fully digital dealings with Spanish authorities. Guide: FNMT digital certificate.
Frequently asked questions
Is there a digital NIE?

What is the FNMT certificate in relation to the NIE?
A digital certificate cryptographically bound to your NIE — the practical 'digital identity' for Spanish administration.
Can I get a NIE itself online?
The application is not fully online for DIY filers — but the POA representative route is 100% remote on your side.
