Can I cross the border from Ioannina Greece to Albania with my Greek ID card or do I need a passport?
EU citizens have been allowed into Albania with their national IDs since summer 2006
As stated by the Albanian MFA (page 1):
GRQIA: PASAPORTË & LETËRNJOFTIM
GREECE: PASSPORT OR ID CARD
However, in countries outside the EU/EFTA, such as Albania, only the new, bilingual card is a valid travel document.
