Can't activate Cl@ve Permanente — activation code, lockout and password

For: anyone who has already registered for Cl@ve with their NIE and cannot get in with Cl@ve Permanente. When: at the first activation, right after registering, or when you lose the code or the password fails. What it explains: activation asks for “DNI/NIE, Email, Activation Code you were given at the time of registration” and a code by SMS; if you have not kept the code, “you can regenerate it immediately”; if you enter it wrongly “more than 5 times”, the system “will block the activation code”; with a forgotten or blocked password, “you can set a new password as long as you have kept the activation code”.

In Activación de usuario, with your NIE, your email, the activation code and a code by SMS

Activación de usuario asks for: “DNI/NIE, Email, Activation Code you were given at the time of registration.”
Then: “If they are correct, the system will send you an SMS with a single-use numeric code (One Time Password, OTP) that you must type in the corresponding form field.”
Before you try again, find your case: do you still have the code? Have you already failed several times? Did you register less than a day ago?

If you lost it, regenerate it at the Agencia Tributaria (the Spanish tax agency) or in the Cl@ve app; if it is blocked, the Portal Cl@ve says to repeat the registration

If you have not kept it: “If you have not kept this code, you can regenerate it immediately from the service ‘Regenerar código de activación de Cl@ve Permanente’” (section 3).
If it is blocked, the Portal Cl@ve states: “it will be necessary to generate a new activation code, for which you must carry out the registration in Cl@ve again.”
Registration routes: in-person registration or registration with CSV.

1. After the SMS code, you set your password

Last step of Activación de usuario: “the system will let you set the password you prefer”.

  • “It must have a minimum length of 8 characters.”
  • “The password cannot contain the first name, surnames or DNI.”
  • “If the password has a length equal to or greater than 16 characters, there will be no restrictions on the type of characters to use”
  • Keep the activation code (section 4).

2. “Usuario no registrado” right after registering: the notice asks you to come back after 24 hours

If you have just registered and activation responds “Usuario no registrado”, the notice says:

3. Lost code: regenerate it on the Agencia Tributaria website or in the Cl@ve app, with the support number to hand

These are the two routes if you have not kept the code.

  • On the web, go to Regenerar código de activación de Cl@ve Permanente: “After identifying yourself with Cl@ve or with a digital signature (electronic certificate or electronic DNI), you must enter the support number (número de soporte) of your identity document to continue.”
  • On your phone: “in the application for mobile devices […] by going into the ‘Gestiones’ category”.
  • On the TIE: “If your document is a foreigner card, the support number appears on the front and consists of 8 digits preceded by the letter E. Example: E87654321.”
  • On the EU citizen certificate: “the support number is on the back of the card.” “Write this number preceded by the letter ‘C’. If this number has fewer than 8 digits, it must be completed with zeros on the left.” “Example: If your certificate has the support number 9999999, you must enter C09999999.”
  • “On older certificates, folio size, the certificate number (support number) appears on the front, at the top right.”
  • With the new code, go back to Activación de usuario; if you had already activated Cl@ve Permanente, go to “olvido de contraseña” (section 4).

4. Forgotten or blocked password: “olvido de contraseña” with the activation code you kept

For the password, the Portal Cl@ve states: “If you forget your password or it is blocked because the maximum number of 5 failed attempts has been exceeded, you can set a new password as long as you have kept the activation code.”

  • Go to “olvido de contraseña” (Portal Cl@ve instructions) and set a new password.
  • If you have not kept the code, regenerate it first (section 3).

5. If another person registers with your number, your registration is left without a phone

For anyone who shares a mobile, the Portal Cl@ve warns:

  • “If another person registers with your same number, you will be left without a phone associated with your registration”
  • To link another number, follow the change-of-mobile section in Cl@ve.

What to do

Follow only the step that matches your case.

Bring

  • NIE
  • Email address
  • Activation code, the original or a regenerated one
  • Mobile phone linked to your registration
  • Support number of your TIE or EU certificate, if you will regenerate the code
  • To regenerate on the web: Cl@ve, an electronic certificate or DNIe to identify yourself

Steps

  1. Have the details on the list to hand and go to Activación de usuario.
  2. If the notice is “Usuario no registrado” and you have just registered, follow section 2.
  3. If you lost the code, regenerate it in the Agencia Tributaria service or in the Cl@ve app (section 3).
  4. If the password is what fails, go to “olvido de contraseña” (Portal Cl@ve) with your code.
  5. Finish when the system saves your new password.
