The full guide
What is Cl@ve?
Cl@ve is the identity system that lets you sign in to Spanish government websites. With it you can file your tax return, download Social Security records, book medical appointments in many regions, and use the DGT’s online services. It works alongside the digital certificate: some procedures accept either.
The three ways to use Cl@ve
| Option | How it works | Best for |
|---|---|---|
| Cl@ve Móvil | Approve a notification in the Cl@ve app | Everyday use, no password to remember |
| Cl@ve PIN | A short code valid for a limited time | Occasional use |
| Cl@ve Permanente | A long-lasting password, sometimes with an SMS code | Frequent users |
How foreigners register
You need a residence document showing your NIE (a TIE, an EU registration certificate or a residence permit) plus your passport. EU citizens can use their national ID card instead of a passport. You also need a mobile number and an email address.
| Method | What you need | Notes |
|---|---|---|
| Invitation letter | Your NIE and a postal address the Tax Agency has on file | Gives a basic level; the letter takes days to arrive |
| Digital certificate | An FNMT certificate installed on your computer | Fastest if you already have one |
| In person | Your documents at a registration office | Some offices need an appointment |
| Video call | A Spanish DNI | Not currently available for NIE holders |
Basic versus advanced level
Registering by letter gives a basic level, which works for many services but not all. Registering in person or with a digital certificate gives an advanced level, which unlocks everything. If a service says your level isn’t high enough, visit a registration office.
Common problems
The letter never arrives. It goes to your fiscal address. If you’ve moved, update your address with the Tax Agency first (form 030), or register in person.
“Datos no coinciden.” Your name or document details don’t match the records. Use the exact format on your TIE, including both surnames if you have them.
New phone. Cl@ve Móvil is tied to your device. Re-activate it on the new phone, or you’ll need to register your number again.
Frequently asked questions
Do I need Cl@ve if I have a digital certificate?
Not strictly, but having both is useful. Some regional health and booking services only accept Cl@ve, and the app is easier on a phone.
Can I register before I have a TIE?
Generally no. You need a residence document showing your NIE. Get your TIE first.
Is Cl@ve free?
Yes. Registration and use are free. Don’t pay a website that offers to “activate” it for you.
