The conscription number is given before the slash and is the number that identifies each separate building of a permanent nature in the municipality. In the Czech Republic, conscription numbers are a type of house number. Compared to the orientational number, the conscription number is unique. The conscription numbers are not repeated for a specific part of the municipality. That is why they are also longer, sometimes up to five digits.
The conscription numbers are red plates with white numbers on the houses, usually including the name of the cadastral area. The conscription number is usually assigned after the building has been approved and is a prerequisite for registration in the cadastre. The building then bears the conscription number assigned to it permanently. A new building built on the site of a demolished building does not inherit a number but receives a new conscription number. The higher the number, the newer the building.
In the Czech Republic and Slovakia, the landmark number is an additional number that is unique within a street or public space. It is assigned by the municipal authority, one at a time within a single public road or space. This can result in a single house having multiple landmark numbers – for example, if it faces a square and also faces a side street, it will have two landmark numbers. In other words, each building can then have as many landmark numbers as there are streets or squares around its walls.
The orientational number
It should be noted that the orientational number is not mandatory in the Czech Republic. Therefore, orientational numbers may not be found in all municipalities. On the other hand, the number may also include a letter (e.g. 2a, 8c) – this is for the sake of clarity and better orientation. You can recognize these numbers by the fact that they are written in white numerals on the blue plates, unless they are painted and individually produced.
The registration number is used to identify buildings and structures that are used for occasional living and are not marked with a conscription number. This implies that they are not buildings intended for permanent habitation. Most often, cottages, cabins, other recreational buildings, etc. have a registration number. The registration number is again unique within the municipality, but the registration numbers form a separate number series, i.e. in the same part of the municipality there may be two buildings with the same number, one of which is descriptive and one registration. The plates on which the registration numbers are shown are colour-coded to differentiate them from both descriptive and indicative numbers (for example, for recreational buildings around Prague it is common to have a yellow plate with black numerals, whereas more recent registration numbers are often white on a green background).
A parcel number indicates a plot of land in a cadastral area. In each cadastral area, parcels are identified by numbers either in two numerical series, separately for land and building parcels, or in one numerical series, regardless of the type of land.
The parcel number is determined within the framework of the cadastral administration when the parcel is created and may be changed later (e.g. when cadastral territory boundaries are changed, when cadastral territories are merged or divided, etc.).
If you know the parcel number and the cadastral area, you can easily find out the area of the land, the owner of the land, whether the land is encumbered, the list of BSEU (Bonitated Soil Ecological Unit) and many other information.
