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

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

You can also request the letter from the Cl@ve PIN app.

• If it is a NIE: the support number on the document will be requested.You can display the help links “How to find the support number...”, explaining where to find this information on your foreign-national card, residence permit or EU citizen certificate, and how to fill it in correctly on the registration form.For more information on the support number, you can also consult the help point "Enter a valid support" (How to enter the support number)".
