Vehicle registration plates of Slovakia

Vehicles registered in Slovakia are generally assigned to one of the districts ("okres") and since 1997, the licence plate coding () generally consists of seven characters and takes the form XX-NNNLL, where XX is a two letter code corresponding to the district, NNN is three digit number and LL are two letters (assigned alphabetically).
Appearance.
There are three design varieties that are in valid use.
At the same time, the creation system will be abolished
registration number based on the abbreviation of the district,
whereas its presentation on the table will no longer lose its meaning
justification. The composition of the registration numbers will remain
the same (2 letters - 3 digits - 2 letters), but
registration numbers will start to be generated again from
combination AA-001AA.
Types.
Where limited space warrants it, two-line plates can be used on a vehicle. A block of combinations is set aside from the regular plate range as required.
Districts.
There are 79 districts in Slovakia. In 69 cases, the district is named after and the code derived from its principal city which is included in the district. Two cities, Bratislava (the capital) and Košice (KE), consist of 5 and 4 districts respectively. This fact is not reflected on the plates, only one code is used. Additionally, Košice-okolie (KS) comprises an area around Košice (the city itself excluded) while having its seat in the city proper.
Each district is assigned at least one code. Ten cities including eight seats of the region ("kraj") are assigned more. Since 18 August 2010, Bratislava has been registering plates with its second code, BL. The Ministry of Interior of the Slovak Republic held a Facebook poll as the reaction to public dissatisfaction of Bratislava inhabitants with the previously intended BD code. As the combinations of the BL code are to be exhausted soon, another Facebook poll was organised in November 2018. Participants were asked to vote for the next code in three rounds (two semi-finals and one final). As much as 89% opted for the BT code over the BE. Bratislava is the only "okres" to do so and will remain in this position for years as Košice, the runner-up, has only reached the ML series as of August 2019.
Former system.
The older system (Slovak: "ŠPZ, štátna poznávacia značka") XX NN-NN or XXY NN-NN - was issued until 30 March 1997. All such registrations expired on 1 January 2005, vehicles that had not registered under the new system are not allowed on public roads.
