How to register in Cl@ve

Register in Cl@ve online with invitation letter and CSV (basic level)

To identify yourself with Cl@ve in the procedures that accept it as an identification system, you must be previously registered in this electronic identification system.

If you do not have an electronic certificate, you can register online, either by requesting the invitation letter (sent by post to your tax address) and completing the registration with the Secure Verification code ( CSV ) or by video call ( Temporarily unavailable ).

Note: Registration via CSV or video call represents a basic level of registration in Cl@ve . Some organizations other than the AEAT may require an advanced level (in-person registration or with electronic certificate/ eDNI ) to access their most common procedures.

Below we detail the steps required to register with CSV :

Access the option " Register in Cl@ve " on the website.

You can also request the letter from the APP Cl@ve . When installing the application and activating the user, if it detects that you are not registered in the system Cl@ve it will give you the option to register. Also by going to "Management" located in the menu at the bottom of the screen and clicking "Registration in Cl@ve ".

Start the registration process by indicating DNI / NIE .

• ID : 8 numbers and letter (no space or hyphen)
• NIE : Letter 7 numbers and letter (without spaces or dashes)

Depending on the type of document indicated, different additional data will be required below:

• If it is a DNI : indicates the validity date. In the case of permanent DNI (with validity period 01/01/9999), the requested data is the date of issue. At the bottom, you have two help links that explain how to locate the validity/issue date on the different types of DNI .

• If it is a NIE : the support number that appears on the document will be requested. You can display the help links "How to obtain the support number...", which explains how to locate this information on your foreigner card, residence permit or EU citizen certificate and how to enter it correctly in the registration form. For more information about the support number, you can also refer to the help "Enter valid support" (How to enter the support number)".

By pressing "Continue" the data entered will be validated. If they are correct, the next window will offer the two ways to register online without an electronic certificate: with CSV , upon request for an invitation letter, and by video call ( Temporarily unavailable ).

Click on the button "Yes, send me an invitation letter to my tax address" .

If the request is saved correctly, a message is displayed confirming the sending of the invitation letter to the tax address that appears in our databases at that time. Click the "Accept" button.

Once you have received the letter you will have 60 days to use it. Complete the registration by accessing the same option " Register in Cl@ve " of the "Registration Cl@ve " portal again and providing the requested data: DNI / NIE and validity/issue date or support number. This time, select option "I already have an invitation letter" and press button "Continue" . Please note that you have 60 days to use it, after this time the CSV will expire.

In the next step, fill in the 16-character Secure Verification Code ( CSV ) that appears on the letter and click "Continue." If you can't find it, please see the help "How to get the CSV in your invitation letter?" below.

If it has been 60 days, the CSV in the invitation letter will have expired. In this case, you will receive a notice indicating that the CSV has expired, and you can request a new invitation letter or register via video call (Temporarily unavailable) , in person or with a certificate/ electronic ID .
