Social Security Number - Who applies for it, employer or me?

@Alex9911

You've got an EU passport, so you're entitled ("Free Movement") to relocate to Spain and work.

So I suggest you make the move, and go find yourself a fancy place to live near your new office. :-)

I believe social security number can be obtained by your employer, or by you. But if you want to ask for it, it probably needs to be in person (i.e. not while you're still chillaxing in Dear Old Blighty).

Padron is the certificate issued by your local town hall. You need a rental contract (or own a property) to get one. The padron is the equivalent of the German Anmeldung.

One you get to Spain, go do your EU Citizen Registration. The process is described here:

You'll need to provide your employment contract to prove that you are a "trabajador por cuenta ajena".

"If you are an employee, you may provide any of the following documents:

- Employer hiring statement or employment certificate, including, at least, the name and address of the company, tax identification and contribution account code.

- Employment contract registered with the Public Employment Service, or communication of the contract and its conditions through the CONTRAT@ platform.

- Registration document or situation assimilated to registration in the corresponding Social Security regime or consent to verify the data in the files of the General Treasury of the Social Security."

I don't think padron or other proof of address is needed, but you can check the requirements listed above.

You apply for an appointment online, at your local (to your new job/apartment) immigration office. Then go there with required documentation. They will (should) give you a little registration certificate, which helps with all manner of subsequent bureaucracy. :-)
