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 (Slovak: EČV, evidenčné číslo vozidla) generally consists of 7 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).
There are three design varieties that are in valid use.
- Between 1 April 1997 and 30 April 2004, the plates contained the Coat of Arms of Slovakia in the top left corner and the country code SK in the bottom left. The two district identifiers were separated from the serials by a dash.
- On 1 May 2004, Slovakia joined the European Union. In order to harmonise the visual look of the plates with the rest of the EU, the Slovak Coat of Arms was replaced by the so-called euroband, a vertical blue bar with representing the Flag of the EU. The country code SK was inserted into the euroband. The number 0 and letter O have been differentiated as well, the number has a stroke through it (similar to the German font.)
- The latest type has been used since 1 June 2006. The Slovak Coat of Arms has returned to the plates replacing the dash while keeping the EU part intact.
Types of Plates 
- Regular plates are the most commonly used of all the types. They contain seven characters starting with the district code (see below) followed by a series of 3 numbers and 2 letters. The number series used are between 001 and 999. The letter series are between AA-XZ and ZA-ZZ. 24 letters are used (excluding Q, W and Slovak letters such as Š). Progression: 001AA-002AA...999AA, then 001AB-999AB. 999AZ is followed by 001BA through 999BB etc. Only Bratislava has reached 999ZZ as of February 2011.
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.
- Trailer plates follow the format of the regular plates XX-NNNLL except in this case the first serial letter is always Y. The registrations would thus start 001YA, continuing through 999YA and 001YB to 999YZ. Any build of trailer whether a mobile home or cargo trailer can use these plates. As of February 2011, Bratislava is nearing the end of its YZ series. Two-line plates also exist with a block of combinations set aside for them in each district.
- Motorcycle plates follow the same coding and use the same series as the regular plates. For example, DS-125AC can be both a regular plate and a motorcycle plate. The only difference is their size. Motorcycles use two different sizes both of which are smaller than the regular size.
- Personalized plates are optional in Slovakia for an extra fee. The format must include the two letter district code and 5 other characters in either XX-LLLLL, XX-LLLLN or LLLNN format. Unlike in any other type of plates, the use of Q and W is possible. Plates are not allowed to display any political, religious or offensive message. Smaller plates are available for motorcycles.
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. Eight cities that are also seats of the region (kraj) are assigned more. Since 18 August 2010, Bratislava has been registering plates with its second code, BL. 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 Hx series as of March 2011.
Former system 
The older system (Slovak: ŠPZ, štátna poznávacia značka) XX-NNNN or XXY-NNNN - 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.
