Polling stations opened at 9am and will close at 8pm.
If you are inside the polling station when the clock strikes 8pm, but still haven't voted, you will still legally be able to complete your vote.
When you arrive at your local polling station you will first need to identify yourself. You can use several different official documents or cards to identify yourself. These include:
National identity document (DNI) if you have Spanish citizenship
Driver's licence (with photo)
Green EU residence card, for citizens of the European Union (remember though this doesn’t include a photo, so you will probably also need your passport or other photo ID)
Foreign identity card or TIE for non-EU nationals whose country has a bilateral agreement.
