In this article, we will see more details and curiosities about this number, what is taken into account when assigning it, and what are some of its functions and advantages.

    External number: what is it?

    Thus, the exterior numbers are numbers associated with the urban nomenclature. For its part, urban nomenclature concerns the identification of real estate by numbers, codes or names. In addition to real estate, the same goes for streets, passages, squares … in any urbanization, town or city.

    When assigning the outside number of a house, the first thing to do is to determine what type of accommodation it is: Single or multi-family. After identifying this aspect, the corresponding name or numbering is chosen, which will be part of the urbanization where the house is located.

    What does the external number depend on (i.e. the assigned numbering)? Basically, of three parameters: ordinances, characteristics of the place and local statutes; it is the latter which oblige the owners to identify their house and their land.

    Why are the houses numbered (exterior number)? Basically, so that the growth of cities is done in a constant but sustainable way, but also for the questions of regulation, control, identification and order.

    1. Location

    The outside number helps us locate houses and different plots of land.

    2. Identification of any construction on the ground

    On the other hand, the numbering system goes beyond housing (both single-family, such as single or semi-detached houses, and multi-family, which would be residential buildings, for example). like that, is extrapolated to street lights, parking lots …

    3. Application

    When do the exterior number and the urban nomenclature apply? When the population in question is more than 10,000 inhabitants.

    4. Identification

    Another utility of the exterior number and street or space nomenclature is that it allows letter carriers to identify the house or building in question when distributing relevant correspondence or deliveries.

    5. Utility

    On the other hand, this system of numbering and urban nomenclature, it allows emergency services (e.g. police and fire brigade) to reach their destination easily and quickly.

    6. Location and location

    Another advantage of the outside number and street name, and perhaps the most obvious, is that they allow us to identify and locate the different directions that we are using or to which we need to go, whether for reasons of leisure, work, studies ….

    7. Control

    Another interesting fact in this regard is that urban numbering helps to control and monitor what diseases (and how many) the population is suffering from (and they are spreading there).

    8. Policy

    Another function of this nomenclature is found at the political level, because it makes it possible to distribute the inhabitants according to certain polling stations.

    9. Basic services and telecommunications

    On the other hand, nomenclature and numbering, allow people and companies who work offering basic services of water, light, wiring, telecommunications … to identify houses. On the other hand, the collection of tariffs is also streamlined in this regard.

    10. Improvements

    Another advantage is the ease that this resource offers implement public assistance and planning plans. It also facilitates the improvement of streets, buildings, homes …

    11. Identification on the identity card

    Curiously, we find that in some countries it is mandatory to include in the DNI or identity card, the name of the street and the number of the house (outside number) in which you reside. that too it allows the identification of the person and a certain control.

    12. Needs detection

    On the other hand, the exterior number and the name of the streets, allow to identify the needs of a certain sector, and also to study how these needs can be taken care of or solved.

    13. Taxes and tributes

    The tax system (Treasury) also plays an important role in all of this, as through these nomenclatures and numberings, can locate and identify people and the conditions in which they live, In order to determine or classify the taxes that these people have to pay, and what taxes they can obtain according to their area, their accommodation, etc.

    How it works?

    Now that we have seen some of its functions and advantages, we will try to answer: how does the allocation of the exterior number of dwellings work?

    To be realized, a series of elements or aspects must be considered, such as the neighborhood, the apple, the block, the town, the parish … That is to say, the subdivisions taken by the land or area in question must be taken into account.

    From there, place the name, code or number that identifies the house, unit or residential complex. All of this is usually seen on the outside (eg, the outside number discussed throughout the article).

      Single-family and multi-family homes / dwellings

      As we have seen, the assignment of the external number it varies depending on whether it is placed in a single-family house or in a multi-family house. Single-family homes, let’s remember, are single or semi-detached homes; on the other hand, multi-family buildings correspond to residential buildings.

      1. Single-family homes

      In the case of single-family houses (where only one family lives), an external number is assigned to the accommodation, depending on the district in which it is located, the municipality, the apple, the parish, etc.

      2. Multi-family homes

      In the case of multi-family dwellings (eg a residential building, where several families live), they are assigned a unique exterior number which identifies the property / building “as a whole”. In this case, the above rule is also followed.

      Numbering type

      Compared to the external number, there are different types of numbering that are placed in the houses:

      • Metric: is based on the distance (in meters) between a house / house and another.
      • Decametric: numbers and codes are placed at the same distances.
      • Sequential: the most “typical” numbering corresponds to even and odd numbers, alternately.

      Home address

      We talked about the outer number, but … and the inner or inner number? In this case, it is the number, code or name that is included in each neighbor building (neighborhood), which allows us to identify the address of a particular person.

      This number includes the data or elements: the building number, a letter or a name and the apartment number.
