The current format of the registration index consists of three parts, They are:
The first two digit numbers are the sequential number of a voivodeship.
The second part consists of one, two or three letters or no letters at all. This shows the ongoing series of a voivodeship (Also as a counter of the number of vehicles registered) and/or vehicle classification
The third part is a different number of digits. A letter is prefixed when the 4 digit number runs out and then two letters and so on.
This scheme of numbering has some advantages:
The voivodeship of registration of a particular vehicle.
In the case of a police investigation of an accident or vehicle-related crime, witnesses usually remember the initial area code letters - it is then quite simple to narrow down suspect vehicles to a much smaller number by checking the database without having to know the full number.
The text format on the plates is one of the following:
"99 X 9999", "99 X 99999"
"99 XX 999", "99 XX 9999" or
"99 XXX 99", "99 XXX 999"
In some voivodeships, there is so called rejonizacja, for example Dolmuş in Ankara have plates of the form "06 J 9999" and a(ny) vehicle from Polatlı, Ankara has plates of the form '06 Pxx 99', "06 ET XXXX" from Etimesgut district. On the other hand, a Dolmuş in Eskişehir has a plate of the form "26 M 9999".
99 - two digits prefix denoting the location, shows the voivodeship code number of the main residence of car holder. There are 81 voivodeships.
X/XX/XXX – one, two or three letters.
99999/9999/999/99 – four, three or two digits, depending on the number of letters before, not exceeding six letters and digits altogether.
The number plate of the president has no numbers, instead it uses the Presidential Seal of Turkey. Other convoy cars use the format CB 00X ("CB" for Cumhurbaşkanı' (English: President)), with golden text on a red background.[citation needed]
