Descriptive, orientation, registration and parcel number: what is the difference?

a descriptive number, orientation number, registration number and parcel number are not the same thing. a descriptive number or registration number identifies a building, an orientation number helps people find the building in a street, and a parcel number identifies land in the cadastre.

in everyday life, most owners do not pay much attention to these terms. but when selling a house, apartment, cottage, land or checking a purchase contract, they can be very important. correct identification of a property helps prevent mistakes in advertising, the cadastre, reservation agreements and purchase contracts.

as real estate agent Jindřich Svačina, i encounter these terms mainly when preparing properties for sale. owners often know the address of the house, but they are not always sure about the parcel number, cadastral area or whether the building has a descriptive number or a registration number. that is why it is useful to understand the differences.

what is a descriptive number?

a descriptive number is a number used to identify a building. it is typically assigned to family houses, apartment buildings and other buildings of a more permanent nature.

in an address, the descriptive number is often written before the slash. for example, in the address “Dlouhá 125/8”, 125 is the descriptive number and 8 is the orientation number.

the descriptive number is unique within the relevant part of the municipality. this means that two buildings in the same part of the municipality should not have the same descriptive number. however, the number alone is usually not enough for exact identification. the municipality, part of the municipality, street, cadastral area and, for a sale, mainly the data in the cadastre are also important.

on buildings, the descriptive number is often displayed on a plate. in practice, you may see a red background with white digits. the colour design, however, is not the key point. when selling a property, what matters is that the information corresponds to official records and contractual documentation.

a common mistake is to assume that a higher descriptive number reliably means a newer building. in some municipalities, a higher number may indicate later assignment, but it is not a reliable rule for assessing the age, technical condition or value of a property.

what is an orientation number?

an orientation number mainly helps with orientation in a street or public space. in an address, it is usually written after the slash.

example: “Masarykovo náměstí 52/14”. the number 52 may be the descriptive number and 14 the orientation number.

the orientation number relates to a street or public space. this means one building may have more than one orientation number, for example if it stands on the corner of two streets. in that case, one side of the building may have one orientation number and the other side another.

not every municipality uses orientation numbers. they are more common in towns and larger municipalities with named streets. sometimes the number also includes a letter, such as 12a or 8b. this helps distinguish buildings or entrances in the same street.

when selling an apartment in a larger building, the orientation number is useful for practical orientation of buyers, photographers, valuers, technicians or the buyer. however, contracts and cadastral documents require more precise identification than just a common address.

what is a registration number?

a registration number is used for certain buildings that do not have a descriptive number. typically, this includes recreational buildings, cottages, cabins and buildings intended for individual recreation.

in practice, it may appear as “č. ev.” or “ev. č.”. for recreational properties, this information is very important because it helps distinguish a cottage or another recreational building from a standard family house with a descriptive number.

a registration number does not automatically mean that the property is worse or impossible to sell. it does mean, however, that the purpose of use, cadastral record, access, technical condition, financing options and buyer expectations should be checked carefully.

this is especially important when selling recreational properties in south bohemia, the vysočina region or central bohemia. for cottages and cabins, buyers often consider not only the location and atmosphere, but also the legal and technical usability of the property.

what is a parcel number?

a parcel number does not identify a house, but land. every parcel is recorded in a specific cadastral area and has its own parcel number.

the parcel number is essential when selling land, a family house, cottage, agricultural property or investment property. it is used in the cadastre to find the specific land, its area, type of land, method of use, owner and any registered restrictions.

in some cadastral areas, you may encounter a distinction between building parcels and land parcels. a building parcel is often marked with the abbreviation “st.”. for older houses or recreational buildings, it is therefore important not to confuse the parcel number of the land under the building with the parcel number of the garden, access road or neighbouring land.

example: a house may stand on a building parcel, the garden may have another parcel number and the access road may be a separate parcel. when selling, it is necessary to know exactly what is being sold and whether all related land is correctly included in the documentation.

why are these numbers important when selling a property?

when selling, it is not enough to say that you are selling “a house in the village” or “land behind the house”. the property must be identified precisely.

correct data is important especially for preparing the listing, estimating market value, checking the title deed, preparing the reservation agreement, preparing the purchase contract, dealing with the buyer’s bank, arranging attorney or notarial escrow and filing the application for registration in the cadastre.

an error in a descriptive, registration or parcel number can cause delays, confusion or the need to correct documents. for more complex properties, such as a house with several plots of land, a cottage accessed over someone else’s land or an inherited property, checking the data is even more important.

how to verify the data in the cadastre

basic information can be verified through the online cadastral viewing system. you can search by parcel, building, unit or title deed.

for precise identification, you usually need to know at least the municipality, cadastral area and parcel number. for buildings and units, a descriptive or registration number can also help.

in the cadastre, you can check the owner of the property, land area, type of land, building or land parcel, registered restrictions and whether the building and land logically correspond to each other.

when preparing a sale, i recommend checking not only the house or apartment itself, but also related land, access, garden, garage, cellar, share of common parts of the building and any easements.

typical situations from practice

with a family house, the most common combination is a descriptive number and several parcel numbers. the owner knows the address, but often does not realise that the garden, access road or ancillary building may be recorded separately.

with an apartment, it is important to distinguish the address of the building, the unit number and the share of common parts of the building and land. selling an apartment in the cadastre is not based only on the number on the doorbell or the apartment door.

with a cottage or cabin, it is necessary to check whether the building has a registration number, how it is recorded in the cadastre, which land it stands on and whether access is properly secured. this can affect the price, financing and buyer interest.

with land, the key information is the parcel number, area, type of land, zoning plan, access and connection to infrastructure. the parcel number is the starting point of the check, not the whole assessment of saleability.

the most common mistakes when working with property numbers

owners sometimes confuse the descriptive number with the orientation number. in everyday communication, this may not matter, but when preparing contracts it does.

another common mistake is confusing a parcel number with a descriptive number. the house number identifies the building, while the parcel number identifies the land.

a further problem arises when a house is sold but related land, a share in an access road, a garage or an ancillary building is forgotten. the buyer may then find that the scope of the sale does not match what they expected.

it is also risky to rely on old documents without checking the current cadastral records. with inherited properties, older houses or recreational buildings, it is worth verifying everything before launching the sale.

what to do when you are not sure

start by preparing the address, title deed and, if available, an older purchase contract, gift agreement, inheritance decision or geometric plan. then verify the information in the cadastre.

if you are selling only an apartment in a standard apartment building, the check is usually simpler. if you are selling a family house, land, cottage, cabin or inherited property, i recommend checking the entire property package before advertising.

correct identification is the basis of a safe sale. when this is resolved at the beginning, it reduces the risk of complications with the buyer, bank, lawyer and cadastre.
