How do I get a social security number?

[UKmember]

Hi,
I have my NIE Number and getting an offer of employment sent to me as I understand this is a requirement to get a SC number.

How do I get the social security number?
What forms do I need?
How much does it cost?

Thanks all!

The company you will be going to work for will sort the SS out, not something as far as I know you need to worry about prior to obtaining your work contract.

That's nice cause I will get my NIE soon and I was not sure about that.
