The Social Security number allocated to you will be sent to you by the Social Security on a card (cartilla) with your full name and Identity Card number on it.

However, as the relevant powers have been devolved to some Autonomous Regions, in some cases you will have to apply for another, more up-to-date card with a magnetic strip and/or micro chip, available from health centres.
