Iso Roobertinkatu 36–40. In the rural parts of Finland, a variant of this method is used. As in towns, odd and even numbers are on opposite sides of the road, but many numbers are skipped. Instead, the house number indicates the distance in tens of metres from the start of the road. For example, "Pengertie 159" would be 1590 metres from the place where Pengertie starts. Netherlands When more buildings are constructed than numbers were originally allotted, discontinuity of numbering is avoided by giving multiple adjacent buildings the same number, with a letter suffix starting at "A". The "Bis" suffix is used occasionally. Each house or apartment can be uniquely identified by a combination of a postcode, a street number and a suffix. Apartments within the same building can be distinguished various ways: by assigning each apartment their own street number, by assigning a simple prefix (generally a letter) or by assigning a complex prefix that takes into account both the floor and the apartment on the floor (e.g. B3). In Haarlem, Netherlands, red numbers are used for upstairs apartments. Portugal In Portugal, the European scheme is most commonly used. However, in Porto and several other cities in the Portuguese Northern region, as well as in the Cascais Municipality (near Lisbon), houses are numbered in the North American style, with the number assigned being proportional to the distance in meters from the baseline of the street. Lisbon numbering is European and furthermore 'from the river, odd numbers left'. Because the Tagus borders Lisbon on the south and the east, this means that north-south streets are numbered low from the south, and east-west streets are numbered low from the east. In many new planned neighborhoods of Portugal houses and other buildings are identified by a lote (plot) number without reference to their street. This is in law the número de polícia, which literally means police's number – the police formerly assigned the numbers rather than the town hall. The lote is the construction plot number used in the urban plan, a consecutive number series applies to a broad neighborhood. In theory and in most cases, the use of a lote number system is provisional, being replaced by a traditional street number system some time after the neighborhood is built and inhabited. In some neighborhoods, lote numbers are kept for many years, some never being replaced by street numbers. The relatively new
