House numbering schemes vary by place, and in many cases even within cities. In some areas of the world, including many remote areas, houses are not numbered at all, instead simply being named.

 the most common house numbering scheme is to number each plot on one side of the road with ascending odd numbers, from 1, and those on the other with ascending even numbers, from 2 or sometimes 0. The odd numbers are usually on the left side of the road, looking in the direction in which the numbers increase. Where additional buildings are inserted or subdivided, these are often suffixed a, b, etc. (in Spain and France, bis

, quater). Where buildings are later combined, they may use just one of the original numbers, combine them ("13/15"), or give their address as a range (e.g. "13‑17"; not to be construed as including the even numbers 14 and 16). Where some plots are not built upon, there may be considerable gaps in the numbering scheme. If a lot of buildings are later built along a stretch of the street, either a range of unused numbers above the current highest house number may be used, introducing confusing discontinuities, or the remainder of the street must be renumbered.

British houses started being numbered with the Postage Act of 1765. In rural areas many houses remain named but un-numbered. The odd numbers will typically, although not always, be on the left-hand side as seen from the centre of the town or village, with the lowest numbers at the end of the street closest to the town centre. Intermediate properties usually have a number suffixed A, B, C, etc., but there are several that have been given a half number, e.g. the old police station at 20½ Camberwell Church Street. At least one property (built next to no.2 after the street had been numbered) has been numbered zero.
Before the early/mid nineteenth century, it was common in England for numbering to proceed sequentially along one side of the road and then back down the other (in a similar way to "boustrephedon" writing). Subsequent changes to local numbering can present pitfalls to researchers using historic street directories

 súpisné číslo). The descriptive number is unique within the municipal part (a village, a quarter, mostly for one cadastral area) or within a whole small municipality.

For makeshift and recreational buildings in the Czech Republic, "registration number" (evidenční číslo) from a separate number series is used instead of the descriptive number. Somewhere, this number begins with zero or with the letter "E" or has different colour to distinction or contains words like "nouzová stavba" (= makeshift structure), "chata" (= ca. weekend house) etc.

In some of settlements where streets have their names (mostly in cities), there are used also the "new" or "orientation numbers" (Czech orientační číslo, Slovak orientačné číslo) concurently. The orientation number is given by sequention within the street or square. If the building is corner or have two sides, it can have two or more orientation numbers, one for every of the adjacent streets or squares. Solitary houses distant from named streets have no orientation number usually. Somewhere, a name of a small quarter is used as a street name. If there is a new building between two older numbered ones, the orientation number is distinguished with an additional lower case (the sequention can be 5, 7, 9, 9a, 9b, 9c, 11, 13). In 1930s–1950s in Brno, lower cases were used for separate entries of modern block houses perpendicular to the street.

Either number may be used in addresses. Sometimes, businesses will use both numbers to avoid confusion, usually putting the descriptive (or registration) number first: "Hlavní 20/7." The two (or three) types of numbers are commonly distinguished by colour of the sign. Every municipality can have their own traditional or official rules and colours. In Prague

In many Bohemian municipalities, descriptive numbers are blue, black or are not unified. In Brno and some Moravian and Slovakian cities, descriptive numbers are white-black signs, orientation numbers are red-white signs. Many cities and municipalities have different rules.

Formerly, roman numerals signifying the municipal part were added to the description number: e. g. "125/III" means descriptive number 125 from the municipal part with number III (in Prague

). Roman numerals were used in both in cities and in village municipalities with more settlements. Nowadays, the name of the settlement is preferred instead of roman numerals.

The first descriptive numbering was ordered by Maria Theresa in 1770 and implemented in 1770–1771. The series was given successively as the soldiers went through the settlement describing houses with numbers. Thereafter, every new house get a next number independently on their location. Most of villages use their original number series from 1770–1771. In cities, houses was one or more times renumbered in order to be sequential – the first wave of renumbering come in 1805–1815. In 1857, the Austrian emperor allowed a new system of numbering by streets. This new system was introduced in the biggest cities (Prague, Brno) in 1860s. In 1884, land registration books was introduced and they used the old (description) numbers as a permanent and stabilized indentificator of buildings. The new (orientation) numbers stay to be used concurrently.

The double numbering existed also in some Austria

Russia and former USSR countries

In Russia
Russia or , officially known as both Russia and the Russian Federation , is a country in northern Eurasia. It is a federal semi-presidential republic, comprising 83 federal subjects...

 and many other former USSR countries, the European style is generally used, with numbers starting from the end of the street closest to the town center. Buildings or plots at street intersections may be assigned a composite number, which includes the number along the intersecting street separated by a slash , like in Нахимова, 14/41 (14 is the number along Nakhimova street and 41 is the number along intersecting street).

The odd numbers are usually on the left side of the road, looking in the direction in which the numbers increase; though in some cities (including Saint Petersburg
Saint Petersburg

) the odd numbers are on the right side.

In some cities, especially hosting large scientific or military research centers in Soviet time, the numbering might be different: houses may have numbers related to the block rather than the street, thus 12-й квартал, дом 3 (Block 12, House 3), similar to the Japanese and Korean systems (see below). Aktau

 is one example of this.

When a numbered plot contains multiple buildings, they are assigned an additional component of the street address, called корпус (building), which is usually a sequentially assigned number unique within the plot (but sometimes contains letters as in 15а, 15б, 15в and so on). So, a Russian street address may look like Московское шоссе, дом 23, корпус 2 (Moscow Street, plot 23, building 2), or Льва Толстого, дом 14б (Leo Tolstoy Street, plot 14, building b).

On very long roads in suburban areas kilometer numbering system also may be used (like Australian rural numbering system). For example, 9-й км Воткинского шоссе (9th kilometer of Votkinsk Highway), and Шабердинский тракт, 7-й км (7th kilometer of Shaberdy Road).

Japan and South Korea

In Japan and South Korea, a city is divided into small numbered zones. The houses within each zone are then labelled in the order in which they were constructed, or clockwise around the block. This system is comparable to the system of sestieri
A sestiere is a subdivision of certain Italian towns and cities. The word is from sesto, or sixth; and is thus used only for towns divided into six districts.

 in Sydney) numbers will typically ascend until the road crosses a council or suburb boundary, then commence again at 1 or 2. Long roads can thus have several occurrences of each number. In semi-rural and rural areas, where houses and farms are widely spaced, a numbering system based on tens of metres or (less commonly) metres has been devised. Thus a farm 2300m from the start of the road, on the right-hand side would be numbered 230.

United States and Canada

On most streets in the United States and Canada, odd numbers are on one side and even numbers on the other. Often the number assigned is proportional to the distance from some baseline, so not all numbers are used. On very long roads, four- and five-digit addresses are common.

 of streets, addresses often increase by 100 for each cross street, though in some cities they are consecutive within each block, so that a block where one side is numbered 501, 503, 505, 507, 509, 511 is followed by a block beginning with 601.

Addresses may also correlate with a street-numbering system. Thus, in Cleveland, Ohio

, use a block numbering system in which a hyphen separates the hundreds digit from the tens digit. For example, a building number that might elsewhere be written 16709 is instead written 167-09. In most cases, the first number refers to the street, avenue, drive, etc. where the numbering begins. For example 99-40 63rd Road is numbered because the starting point was 99th Street. Likewise, an address on a perpendicular block would have its number starting with 63-XX. In Queens (unlike other areas, such as Los Angeles, where one may see numbers such as 16700 Sunset Blvd.) rarely is the 00 number used to refer to an address, but rather the numbering starts at -01 or -02 depending on the side of the block.
