First 30 Days in Spain: What to Do After You Arrive

Why the order matters

Spanish bureaucracy is sequential. You cannot register for Seguridad Social without a NIE. You cannot get a NIE appointment without an empadronamiento certificate in many provinces. You cannot install Certificado Digital without a NIE. You cannot file taxes online without Certificado Digital. You cannot get a long term apartment without a NIE. This means you cannot do everything in parallel. There is a critical path, and if you get it right, your first month feels like progress. Get it wrong and you waste two weeks trying to register for things that require something you have not done yet.

The order we recommend, and the one this guide follows, is: empadronamiento first (because almost everything else requires it), then NIE or TIE (the identity number that unlocks bureaucracy), then bank account upgrade, then Certificado Digital, then Seguridad Social and Tarjeta Sanitaria, then utilities and internet, then long term housing decisions. Do them roughly in that order and the dominoes fall cleanly.

Week 1: arrival and empadronamiento

Days 1 to 3: get oriented and find a Spanish phone number

In your first few days, do not rush to appointments. Get a Spanish SIM card. Lowi, Digi, and Simyo offer prepaid SIMs from 5 to 10 euro per month with enough data to run your life. You need a Spanish phone number for almost every booking system: cita previa, banks, healthcare. Keep your home country SIM in a second slot or eSIM for the first month, but make Spanish your primary number quickly. Walk around your neighbourhood. Find your closest Ayuntamiento, Policía Nacional office, and Centro de Salud. Knowing where they are saves time when you have appointments. Buy a small ring binder. You will accumulate paperwork.

Days 4 to 7: book and attend your empadronamiento appointment

The empadronamiento is your registration at the Ayuntamiento (town hall). In most municipalities you book through the Ayuntamiento website (search 'cita previa empadronamiento [your municipality]'). Some small towns let you walk in. Larger cities like Madrid, Barcelona, Valencia, and Alicante require appointments and waits can stretch to 3 or 4 weeks. Book on day 1 or 2 if you can.

What to bring: your passport (and a photocopy), your rental contract (and a photocopy), and the empadronamiento form (called Hoja Padronal in most municipalities). If you do not have a rental contract because you are staying with someone, you need their written authorisation plus their padron certificate. Some municipalities also require a recent utility bill in the landlord's name. Rules vary by municipality and there is no national standard. Call your specific Ayuntamiento before going.

When you finish, you receive a Volante de Empadronamiento. This is a paper certificate with a barcode and an official stamp. Make several photocopies and keep digital scans. Almost every other step in this guide requires it. Some offices issue the volante immediately; others send it by post or ask you to return in a few days. The volante is valid for 3 months for most procedures.

Week 2: NIE/TIE and your bank account

Days 8 to 10: book your NIE or TIE appointment

EU citizens: book your EX-18 appointment at Policía Nacional, Extranjería division. Non EU citizens with an approved visa: book your TIE appointment (EX-17, called toma de huellas) within 30 days of arrival. Both go through the same booking system (sede.administracionespublicas.gob.es) and the available slots can be brutal in popular provinces. Madrid, Barcelona, Alicante, and Malaga are the slowest.

Tip that nobody tells you: appointments are national, not regional. If your local office shows nothing for 6 weeks, search appointments in a smaller neighbouring province. Driving an hour to a smaller town with same week availability is often faster than waiting 6 weeks at home. The cards and numbers issued are valid nationwide.

Days 11 to 14: open a Spanish bank account and prepare for the appointment

Even before your NIE appointment, you can open a non resident bank account with most major Spanish banks (Santander, BBVA, CaixaBank, Bankinter) using only your passport. Online challengers (N26, Openbank, Revolut, Wise) are faster and offer immediate IBAN. Open one this week. You will need it for paying the Modelo 790 tax for your NIE/TIE appointment, and later for utility direct debits.

Prepare for the NIE/TIE appointment: print and complete the EX-18 form (EU) or EX-17 form (non EU). Pay the Modelo 790 code 012 at any bank or online (approximately 12 euro for EU NIE/green card, 16 euro for non EU TIE) and keep the bank stamped receipt. Get one passport photo in Spanish format (32x26 mm, white background, head facing forward). Have your volante de empadronamiento and your passport ready. For non EU TIE: also bring your residence visa or resolution letter.

Week 3: NIE/TIE appointment and Certificado Digital

Days 15 to 21: attend your appointment and start the Certificado Digital

Arrive at your appointment 15 minutes early. The Policía Nacional staff in Extranjería offices are professional but rarely speak English. Bring a Spanish speaker if you are not confident. Hand over your documents, give your fingerprints (TIE only), and wait. EU citizens receive their green card or A4 NIE certificate on the spot. Non EU TIE applicants are given a date 2 to 8 weeks later to collect the physical card. The NIE number itself is assigned immediately so you can use it.

As soon as you have your NIE, request your Certificado Digital from the FNMT (Spanish national mint). The process has three steps. Step 1: request a code online at fnmt.es. Step 2: take that code, your passport, and your NIE to a Hacienda or Seguridad Social office to verify your identity in person (no appointment needed for this step at most offices; just walk in). Step 3: return to fnmt.es with the verification code and download the certificate to your browser. Total time: 1 to 3 days if you do it consecutively.

The Certificado Digital is the single most useful administrative tool you will have in Spain. It signs tax returns. It accesses the Seguridad Social portal. It accesses the UGE-CE portal for residence renewals. It accesses the DGT portal for vehicle and licence administration. It signs documents legally. Once you have it installed, back it up. Export the certificate file from your browser and store it in a password manager. People who skip this step regret it.

Week 4: Seguridad Social, healthcare, and utilities

Days 22 to 25: register with the Seguridad Social

How you register depends on your situation. Employees: your employer registers you. Self employed (autónomos): you register at the TGSS through the IMPORTASS portal using your Certificado Digital. The first step is the alta en el RETA (registration in the special regime for self employed workers). Non-Lucrative Visa holders cannot register through work and must rely on their private insurance until they qualify for Convenio Especial after one year. UK pensioners with an S1 form: register the S1 with INSS to access public healthcare on UK funding. Family members of registered workers (spouse, dependent children): they get covered automatically through the registered worker.

Days 26 to 28: get your Tarjeta Sanitaria and choose a doctor

After Seguridad Social registration, take your Seguridad Social number, NIE/TIE, and empadronamiento to your local centro de salud. They register you with the regional health service (each comunidad autónoma has its own: SERMAS in Madrid, ICS in Cataluña, SES in Extremadura, and so on). You are assigned a family doctor and a paediatrician for any children. You receive a temporary paper certificate immediately; the physical Tarjeta Sanitaria card arrives by post 1 to 4 weeks later.

Schedule a first appointment with your assigned family doctor in your first month, even if you are healthy. It establishes the relationship, lets them open your medical history, and means you have a doctor on file when you need one. Most centros de salud do not take walk in patients; you need to know how to book and your doctor needs to know who you are.

Days 28 to 30: set up utilities and finalise your bank account

If you signed a rental contract that includes utilities in your name (which is common for long term contracts), now is the time to transfer them. Electricity (Endesa, Iberdrola, Naturgy, Holaluz, or Repsol) requires your NIE, the property reference (suministro/CUPS code on the previous bill), Spanish IBAN for direct debit, and your contract. The transfer itself usually takes 5 to 15 days. Water and gas follow the same pattern. Internet and mobile: Movistar, Vodafone, Orange, MasMovil offer the most coverage; Digi and Lowi are the cheapest. Most plans require a 12 to 24 month commitment so do not sign in your first week.

Upgrade your bank account from non resident to resident. Provide your NIE certificate, your empadronamiento, and proof of income. Resident accounts have lower fees, better mortgage access, and full direct debit functionality.

What to leave for later (months 2 and 3)

Some things can wait beyond your first 30 days, even though they are important. Exchanging your driving licence can be done at any point in your first 6 months for EU/UK licences (the bilateral exchange agreements give you up to 6 months from residence). Buying a car or property is rarely a good idea in your first month. Wait until you understand your neighbourhood, your commute, and your real budget.

Long term apartment search if you are still in temporary housing: most people do this in their second month, after exploring two or three different areas. School enrolment for children, if you have not done it already, follows the academic calendar (March to May for September start). Tax registration and quarterly filings (Modelo 130, Modelo 303) only kick in once you have started working or invoicing.

Common mistakes in the first 30 days

Trying to do everything in parallel

People try to book NIE, empadronamiento, bank, and Certificado Digital appointments all in week 1. Then they discover that the NIE appointment requires the empadronamiento, which they have not done yet, and they have wasted a slot. Follow the order. Empadronamiento first.

Booking appointments without checking what is needed

Every Spanish administrative appointment has a specific document list. The list varies by province, sometimes by individual office. Check the requirements for your specific office before booking. Calling the office directly often works better than reading the website, which is sometimes outdated.

Signing a 12 month rental in week 1

You do not know your neighbourhood yet. You do not know if the heating works in winter (you arrived in summer). You do not know the noise pattern. Wait at least 30 days before signing anything that locks you in for 12 months. The 1 month furnished rental costs more per night but saves you from a 12 month regret.

Not getting Certificado Digital immediately

People put off Certificado Digital because it feels technical. Then they cannot file taxes, cannot register for things online, and have to take a day off work to go to an office every time something needs signing. Get it in week 3. It pays back the time investment within a month.
