Request for the idCAT Certificate

• 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.

To obtain the idCAT certificate in person, you must go to an idCAT Registration Entity to request the certificate and validate your identity. Previously, you can fill out the application form online to make the process faster through https://idcat.cat/ request

Once at the Registration Entity:

1. The operator will compare your document to validate the issuance of your idCAT Certificate.

   • You will need to define a personal code : this code is non-transferable, and therefore only you, as the holder of the certified idCAT, can know it. For this reason, the operator will provide you with the keyboard so that you can define this code yourself, thus guaranteeing that no one else knows it. It is important to remember it because it will be essential to download the certified idCAT.

   • You will need to provide a personal email address where you will receive certificate expiration notices (60 and 30 days before it expires) and where you may receive any informational communication related to the use of the certificate, as explained in the Appearance Document that you will sign when you obtain the certificate. In any case, the AOC Consortium does not use the email address of digital certificates to send advertising of any kind.

2. The operator will provide you with the delivery sheet so that you can sign it and have a copy. This sheet contains the management code , which together with the personal code will allow you to download the idCAT certificate. You will receive the same information in your personal email.
