Applying for a Social Security number in Spain (“Numéro de Seguridad Social”) is an essential task for anyone who plans to earn money while living in Spain for a certain period of time. Like many other important documents that you might need to apply for (NIE/TIE Card, Empadronamiento), the Social Security number will allow you to integrate into life in Spain as a resident and a member of the community. It’s not required for everyone, so be sure to confirm if you need to get the Social Security number for your specific situation in Spain.

1. What is the Social Security Number & Who Needs to Apply for it?

The Social Security number is officially known as the “Número de Afiliación de la Seguridad Social“, but is often referred to as just the “Numéro de Seguridad Social” or the “SSN“. Having it means that you are officially registered as a part of the tax & social security system in Spain and thus you will gain access to many benefits that are a part of the Spanish social system. These benefits include healthcare benefits, social benefits, security and disability benefits, unemployment benefits and other resources that might support you in times of difficulty.

The Social Security number in Spain is required when a person legally living in the country intends to earn money in an official capacity. Unlike other important legal documents that you may need to apply for, the duration of your stay in Spain is not important. You will always need a SSN if you intend to participate in any of the following situations:

  • Being employed at a company
  • Being self employed (autónomo)
  • Being a student taking on a professional, paid internship
  • Being a civil servants or military personnel
  • Being a business owner or business partner

Access to public healthcare is on of the most important benefits of registering to the Social Security system in Spain. Make sure you know everything about healthcare in Spain so you can properly navigate it during your time here. Also make sure that you contract the best private health insurance possible so you’re fully covered!

2. How to Get the Social Security Number in Madrid

Applying for the Social Security number in Spain is not the most straightforward process – but we’re sure you already expected that. Navigating the Spanish bureaucratic systems often make things more difficult than they need to be, with information online being limited and official resources being unfortunately difficult to follow. Trying to navigate those systems without speaking Spanish is just another hurdle you will need to jump over. In this chapter will we go over the important basics for applying for your Social Security number. It will also outline how to make an appointment, what forms you need and what to expect from the process.

2.1 Cita Previa “Seguridad Social” – Making your Appointment for the Social Security Number

To make your appointment (cita previa) for your Social Security Number you need to head to the official website of the Spanish “Seguridad Social”. On this page you need to find the closest office to you and book your appointment via the information the page provides. There is a process for applying for your Social Security number online, however you will be required to have both a NIE/TIE and a special digital certificate. Find out more about the digital certificate here and try applying online here.

  1. In the drop down labeled “Localización” select your location details. In our case it is “Por Municipio” and “Madrid, Madrid“. Once selected click “Aplicar filtros“.
  2. The page will reload to a large list of offices. For the Social Security number appointment you need to look for offices labelled “TESORERIA GENERAL DE LA SEGURIDAD SOCIAL“.
  3. Once you’ve found the office that you’d like to go to, use the contact info provided to request your appointment. You will most likely be directed to a call center and do not be astonished if it is quite difficult to get through to actually request an appointment. Please be aware that you will need to speak in Spanish when contacting the right call center.
