Social Security Number
In order to work in Spain it is necessary to have a social security number. A social security number is also necessary in order to obtain a medical card and to begin making contributions that allow you to receive unemployment benefit and eventually a pension.
How to apply for a Social Security Number
If you plan to work for a company as an employee you can obtain this by filling in form TA-1 at the local Social Security Office and you will be required to bring your passport. A different application procedure applies to the self-employed.
Formerly you would receive a small yellow card but this has been changed and you now receive a print-out immediately at the time of application.
