This number (número de afiliación de la seguridad social) gives you access to the social security services and healthcare in Spain. Social security is generally paid for by the employer. Once you have been entered into the system the number will remain the same for life.
In order to obtain a social security number you will need to download and complete the TA-1 form. The form is not available in English, so you may need assistance from a Spanish speaker.
As well as form TA-1 you will need the following documentation:
- ID or passport plus photocopy
- Rental contract, employment contract if you have them plus photocopy
- NIE, if you have already got it (see Applying for Residence in Spain link for more information).
- Residency papers and visa if you are a non-EU citizen.
You will need to go to your local Tesorería de la Seguridad Social to apply for your social security number. All cities and most large towns have social security offices. They are generally open Monday to Friday from 9am until 2pm. You can find your local office by following this link to the social security website. There is a list of offices or you can click on Buscar Centros on the same page.
It is worth getting there early before they open to avoid being at the back of a long queue. You are also likely to find that people do not speak English and so you should ensure you know the key Spanish terms or take a translator.
