Greek vehicle registration plates are composed of three letters and four digits per plate printed in black on a white background. The letters represent the district (prefecture) that issues the plates while the numbers range from 1000 to 9999. As of 2004 a blue strip was added on the left showing the country code of Greece (GR) in white text and the Flag of Europe in yellow. Similar plates but of square size with numbers ranging from 1 to 999 are issued for motorcycles which exceed 50 cc in engine size.

Patras is Greece's third-largest city and the regional capital of Western Greece, in the northern Peloponnese, 215 km (134 mi) west of Athens. The city is built at the foot of Mount Panachaikon, overlooking the Gulf of Patras.
