All You need to Know about House Numbers in Europ in 2021

House numbering is a method of providing a unique address to every building on a street or neighbourhood to make it much easier to find a specific structure. Historically, the house number was always part of an actual postal address. However, in recent years, the term has referred to any non-postal facility with a lesson, or a vacant lot left vacant.


In many parts of the Europe, house numbers began after the Second World War, when homeowners needed a way to identify their property quickly. For example, a house number letters in Manhattan meant that an individual owned the property, so that if a person missed returning a letter, it would be easy to find the address and notify the owner.

History of house numbers In Europe

While some cities such as London use unique house numbers plaques for upscale residential neighbourhoods, other cities use similar numbering practices for middle-class residential areas. Many cities have now adopted ‘udata’ numbering, which is based on individual homesteads. This means that a house could have the same number from one year to the next, but with different house numbers for each personal homestead. As well as this historical house number practice, newer numbers are often applied to newly built properties, to help facilitate the property’s sale.

Methods of Assigning Door Numbers

A variety of methods are used to assign house numbers to streets. In a relatively small number of cities, the numbers are determined by the street names or historical census blocks. This system works well for small numbers, where it is easy to code and assign. However, setting door numbers to streets can be a rather tedious process for larger roads or areas with many lanes. This is because it requires taking into account several factors such as street names and cross streets, the direction of the street, the orientation of the block’s corner block, and the road’s path and cross streets at various distances from each other.

Cross Street System

Another type of numbering system used is the cross-street system, based on the numbers of individual houses. This system can work for large streets but is less common for medium and small streets. A mixed approach is sometimes seen, where some homes have their numbers in contrast with those that belong to other houses. In these situations, individual house numbers are usually coded to identify them on correspondence.

The most common way to assign numbering to buildings in cities is through a European numbering system. It is called the European System of House Numbering and is essentially the same system used to number street names. The significant difference between these two systems lies in the fact that street names are generally localized while building numbers usually are national in origin. As a result, most of the buildings are assigned with a European number, and streets are given a local number.

Even and odd Home door numbers

One side of Europe uses even numbers, while the other side uses odd numbers. Even numbers are designated for multi-story buildings, while odd numbers are reserved for older single-family residences. For single-family homes, the odd numbers are used. Each country has a different system when it comes to the use of even and odd numbers.

The use of European numbering system can be traced back to the 12th century when it was discovered that writing medieval texts were written in Latin rather than Arabic. With the shift to Latin letters came the need for a standard numbering system. This led to the numbering system we know today. Initially, the numbers for streets and buildings were based on their location in the city. Today, however, numbers are assigned by a person’s first name, regardless of where they live.


There are two official European systems used for numbering streets: the English and the French numbering systems. The English course, which was derived from Latin, is currently the most commonly used system. It is also known as the martingale system, after a French town called Tours.
