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.

The final one or two letters in the sequence changes in Greek alphabetical order after 8,999 issued plates.

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.

For just 2 years the system was L–NN, L–NNN, L–NNNN or L–NNNNN with black characters on yellow background where L was the initial of the city they were licensed in (e.g. "A" for Athens, "Θ" for Thessaloniki etc.).

All these plates display "1953–54" (the initial time period for the change, later revised) in black characters on a white background using a smaller typeface in the top left corner.

Characters were black on white background with a band at the top of both front and rear plates indicating city/district of registration and type of usage (private, commercial etc).

In September/October 2004 the euroband and international country code (GR) were added to the left and the typeface changed.

The first 2 of 3 letters (which are listed below) of a licence plate usually represent the prefecture (nomos) where the car was registered.

The almost full list of plates in Greece is below (next to the prefecture / district is its capital or an area within the prefecture that the plates are issued; some prefectures have more than one combination): Vehicles that belong to public services and armed forces use special license plates with the following letter combinations followed by numbers: [citation needed] The following categories are conflicting: The same letter combinations are used for both public services and specific regions: For truck trailers over 3.5 tonnes without a prime mover: The letter P followed by a hyphen and 5 or 4 numerals is used.
