Vehicle registration plates of Greece

Greek vehicle registration plates are composed of three letters and four digits per plate (e.g. ΑΑΑ–1000) 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.

With the exception of Athens and Thessaloniki which are represented by just the first letter of the three, all other districts are represented by the first 2 letters. The final one or two letters in the sequence changes in Greek alphabetical order after 8,999 issued plates. For example, Patras plates are ΑΧΑ–1000, where ΑΧ represents the Achaia prefecture of which Patras is the capital. When ΑΧΑ–9999 is reached the plates turn to ΑΧΒ–1000 and this continues until ΑΧΧ is finished. The letters are officially letters from the Latin alphabet, but only those letters are used whose shape (as a capital letter) matches a letter from the Greek alphabet, specifically Α, Β, Ε, Ζ, Η, Ι, Κ, Μ, Ν, Ο, Ρ, Τ, Υ, Χ (in Greek alphabetical order). This is because Greece is a contracting party to the Vienna Convention on Road Traffic, which in Annex 2 requires registration numbers to be displayed in capital Latin characters and Arabic numerals. The rule applies in a similar way in Russia, Ukraine, Belarus, Bosnia and Herzegovina and Bulgaria.

Combinations used for overseas residents are L–NNNN (where L = letter and N = number) and are limited. Until 2003, taxis used L–NNNN; the plate was aligned with the prefecture and the letters were colored red.
