This Support Portal is for the idCAT Registration Entities (Public bodies that issue the idCAT to citizens).

If you are a citizen and need support with the idCAT Certificat or the idCAT Mòbil, consult:

What documentation does the citizen need to provide to obtain the idCAT Certificate?

What does the citizen need to obtain the idCAT Certificate?

To obtain the idCAT Certificate, according to Law 6/2020, of November 11, and the conditions of use of the service , you only need to:

  • Be over 18 years old (you can apply from the day after turning 18)

  • Have one of the following identification documents in a valid state (not expired):

    • ID card (from any of the Schengen area member countries ),

    • Passport

    • NIE (must have a photograph, if not, you must provide an additional document (Passport or Schengen ID))

  • Have an email address

NOTES about identification documents:

  • To issue the idCAT Certificate, only the identification documents listed in the previous list are accepted.

  • Foreigners can prove their NIE number by providing the following documents:

    • TIE : in addition to the NIE, it has a photograph and, therefore, is used to issue the idCAT with this card. Please note that according to the applicable regulations, the validity of the TIE card is extended until the resolution of the extension request, provided that the renewal has been requested up to 90 days after its expiration and the corresponding resolution is pending ( Regulations for the development of the Organic Law on the rights and freedoms of foreigners in Spain ).

    • European Union citizen registration certificate : it is necessary to provide another official document with a photograph (for example passport or Schengen area ID card ).

    • Provisional NIE document: it is necessary to provide another official document with a photograph (for example, passport).

  • The administrations have their applications configured to allow electronic processing with certificates made with NIF and NIE; however, it is not common for them to allow access with certificates issued from a passport or DNI from other countries. The procedures that can be carried out independently of the accrediting document contained in the certificate are those that have nothing to do with the public administration, such as, for example, signing documents.

Identification document models:

The DNI certifies the identity of the holder, as well as their Spanish nationality.

From April 2, 2025 and in application of RD 255/2025 , the digital DNI will also be accepted as long as it is displayed in the official MiDNI application. More information at https://www.midni.gob.es/ .

National identity documents from any of the countries that are members of the Schengen Agreement are also accepted. In the case of ID cards from other countries, a photocopy must be provided in addition to the original.

The foreigner identity card (TIE) is a physical document that proves the legal residence of a foreigner in Spain.

There may be two card models, pre-2020 and post-2020.

 The European Union Citizen Registration Certificate is a document that accredits the registration of citizens of the Union in the Central Register of Foreigners. This document must always be accompanied by a document with a photograph, a Schengen area ID card or a passport.
The provisional NIE (Provisional Foreigner Identity Number) is a number temporarily assigned to a foreign person in Spain for administrative purposes while processing or before obtaining the definitive NIE. This number is issued by the National Police (Directorate General of the Police), usually through authorized Immigration Offices or Police Stations. This document must always be accompanied by a passport.
Passport is a personal identification document with international validity, which identifies its holder, issued by the authorities of a country.

Document with an incomplete “Date of Birth” field

In the event that a citizen provides an accrediting document that has an incomplete date of birth, this data must be written in the “Date of birth” field as it appears on the accrediting document. There are some documents (NIE's and DNI's from other countries) in which the date of birth appears without specifying the day and month of birth, and only the year appears. In these cases, instead of the day and month values, “X” appears (XX/XX/1965).

In order to be able to issue the idCAT certificate, the citizen must have reached the age of 18. Therefore, since the day and month of birth cannot be verified, for the purposes of counting the age of 18, it must be assumed that the date of birth was 01/01.

Document without font

In the event that a person wishes to validate the idCAT with an ID card without a letter (the old ones), the citizen will be asked if they have the card on which the Ministry of the Interior reported the letter that corresponded to each number. In this case, a photocopy and certification of this Ministry card will be made and attached to the submission file.

If, on the contrary, the citizen does not have the card with the NIF letter, we will not be able to issue the certificate, since the document they have is a DNI, and not a NIF (which has letters).

Document without surnames
It is not common, but it can happen that a foreign person does not have a surname, and only has the name on the accrediting document. In this case, the system is prepared to be able to issue the idCAT, although it gives a warning to avoid that it is an error, and the idCAT without surnames is not issued to a person who has them on their accrediting document. The cases in which an idCAT without surnames can be issued are when the accrediting document is a NIE, DNI from other countries or a passport, that is, if the document is a NIF, the person's two surnames must necessarily be indicated.
Does the user's physical address have to match the one that appears on the identification document?

The user's address does not have to match that of the identification document; the user can enter whatever they want.

This data will not be included in the certificate, and the sole purpose of collecting this information is statistical.
