Document hub

The official PDF receipt Mercurio gives you the moment your renewal application is signed and submitted. Contains the expediente (file) number, the submission timestamp, and the list of documents you uploaded. This is your proof that the renewal is officially 'en trámite'.

The official PDF notice from the Oficina de Extranjería confirming that your renewal has been approved ('concedida'). It includes your name, NIE, the new authorization period, and a list of the exact documents you must bring to the huellas appointment. The police office calls this 'Esta comunicación' — they will not issue the new TIE without it.

The booking confirmation for your 'Toma de huellas' (fingerprinting) appointment at the Policía Nacional. The PDF includes the date, time, office address, your name, your NIE, and a booking reference code. You must bring it to the appointment — without it, they can turn you away.

The official application form for the Foreigner Identity Card (TIE). Used for the first issuance, renewal, and replacement of the TIE card.

The form you fill in at the Oficina d'Atenció Ciutadana (OAC) to register your address with the Barcelona city council. Required for many other procedures including the TIE.

A special travel authorization that allows you to leave Spain and return while your TIE renewal is in process or while a TIE replacement is being issued.

The application form to renew (extend) your student residence authorization. Used before applying for a new TIE card during renewal.

The certificate that proves you are registered at an address in Barcelona. You receive a basic 'volante' at the time of registration, and can request a more formal 'certificat' afterward.

The official tax form generated on the Policía Nacional sede. The SAME 790-012 form is used for several different government fees — you tick a different 'concepto' (concept) depending on what you're paying for. In the TIE renewal flow you pay it TWICE: once for the renewal authorization (before submitting Mercurio) and again later for the physical TIE card (before the huellas appointment).

The physical card that proves your legal residence in Spain. Contains your NIE number, photo, and the expiration date of your authorization.

Your signed rental agreement with the landlord or housing provider. Used as proof of address for empadronamiento.

An official record of the courses you've completed and the grades you've earned during the period covered by your current TIE. Used to demonstrate you are actively progressing in your studies.

A digital certificate issued by the FNMT (Fábrica Nacional de Moneda y Timbre) that lets you sign documents and authenticate yourself on Spanish government websites. Essential for TIE renewal via Mercurio.
