The various addr keys are used to provide address information for buildings and facilities. See Addresses for more details on usage.

How to map

If it is a point of interest relationareawaynode

Add the required address elements to the object.

If the address applies to an area (e.g. often detached houses, terraced house, buildings including or without associated open areas) area

Add at least the following to the polygon that represents the area (building or site, according to validity of address):

You might consider adding addr:postcode=* on single elements, depending on local mapping practices. Further address tags are optional, since they can usually be determined from the boundary relations (if present and valid).

If the address applies to a point (e.g. entrance, gate) node

Add the following to the node representing the point:

Unless the following are unknown or don't exist, add them as well:

Example on map:

Loading map...

Using addr:country=*, addr:state=*, and addr:province=* are optional, since they can almost always be determined from boundary relations (if present and valid).

If you don't know the extent of the address node

Create a node where you expect the address to be valid. If you can estimate an area it might be better to use this rather than a node.

Unless the following are unknown or don't exist, add them as well:

Using addr:country=*, addr:state=*, and addr:province=* are optional, since they can almost always be determined from boundary relations (if present and valid).

Tags for individual houses

addr:housenumber user defined node area The house number (may contain letters, dashes or other characters).
Addresses describes ways to tag a single building with multiple addresses.
Please do not only tag addr:housenumber=*, but also add at least addr:street=* or addr:place=* for places without streets (or map the belonging to a street with a relation using associatedStreet relation or street relation.)

addr:housename user defined node area The name of a house.
This is sometimes used in some countries like England instead of (or in addition to) a house number.

addr:flats user defined node The unit numbers (a range or a list) of the flats or apartments located behind a single entrance door. Rendering of addr flats 2.png Flat numbers on an entrance.png
addr:conscriptionnumber user defined node area This special kind of housenumber relates to a settlement instead of a street. Conscription numbers were introduced in the Austrio-Hungarian Empire and are still in use in some parts of Europe, sometimes together with street-related housenumbers which are also called orientation numbers.
addr:street user defined node area The name of the respective street.
A way with highway=* or a square with place=square and the corresponding name should be found nearby. The belonging to a street can alternatively be represented by a associatedStreet relation or street relation. The keys addr:housenumber=* and addr:street=* in principle are the only necessary ones if there are valid border polygons. If you are not sure if it is so, just add addr:city=*, addr:postcode=* and addr:country=*.

addr:place user defined node area This is part of an address which refers to the name of some territorial zone (usually a place=* like island, square or very small village) instead of a street (highway=*). Should not be used together with addr:street=*.
addr:postcode user defined node area The postal code of the building/area. Some mappers prefer to use boundary=postal_code
addr:city user defined node area May not be required if boundary=administrative is used correctly. May or may not be a clone of is_in:city=* (in some places the city in the address corresponds to the post office that serves the area rather than the actual city, if any, in which the building is located)! The name of the city as given in postal addresses of the building/area.
addr:country user defined node area May not be required if boundary=administrative is used correctly. The ISO 3166-1 alpha-2 two letter country code in upper case.
Example: "DE" for Germany, "CH" for Switzerland, "AT" for Austria, "FR" for France, "IT" for Italy.
Caveat: The ISO 3166-1 code for Great Britain is "GB" and not "UK". See also: is_in:country=*
addr:full user defined node area Use this for a full-text, often multi-line, address if you find the structured address fields unsuitable for denoting the address of this particular location. Examples: "Fifth house on the left after the village oak, Smalltown, Smallcountry", or addresses using special delivery names or codes (possibly via an unrelated city name and post code), or PO Boxes.
Beware that these strings can hardly be parsed by software: "1200 West Sunset Boulevard Suite 110A" is still better represented as addr:housenumber=1200 + addr:street=West Sunset Boulevard + addr:flats=Suite 110A.

For countries using hamlet, subdistrict, district, province, state

addr:hamlet user defined node area The hamlet of the object.
Grosvenor Place 2 2008 06 19.jpg
addr:suburb user defined node area If an address exists several times in a city. You have to add the name of the settlement. See Australian definition of suburb.
addr:subdistrict user defined node area The subdistrict of the object.
addr:district user defined node area The district of the object.
addr:province user defined node area The province of the object. For Canada, uppercase two-letter postal abbreviations (BC, AB, ON, QC, etc.) are used. In Russia a synonym addr:region is widely used
addr:state user defined node area The state of the object. For the US, uppercase two-letter postal abbreviations (AK, CA, HI, NY, TX, WY, etc.) are used.

Tags for interpolation ways

addr:interpolation all/even/odd/ alphabetic way How to interpolate the house numbers belonging to the way along the respective street.
See detailed description.
Spořilov, Púchovská, označení domu.jpg
addr:interpolation Number n way Every nth house between the end nodes is represented by the interpolation way.
addr:inclusion actual/estimate/potential way Optional tag to indicate the accuracy level of survey used to create the address interpolation way.
See detailed description.

Tags for parts of a building
addr:door user defined node area The door number (or name) of an apartment/flat/office/room. Could also be called differently in some countries (In Austria for example it is sometimes referred to as "Top"). If a room has more than one door, you can tag them separately.
See also: room=*
addr:unit user defined node area The number, letter, or name of a single unit or flat that exists within a larger complex. While a big building could have only one entrance, sometimes the way inside divides into different units or staircases, where certain apartments/flats/offices can only be reached through a specific unit. Useful for apartment, suite, or office numbers. Information necessary for postmen, for example. In the United States, there is no consensus on how to represent secondary unit designators.
addr:flats user defined node area A list of flat numbers accessible in a building or behind a door.
addr:floor Number node area The floor an apartment/flat/office is located. This tag is not commonly used. Please have a look at the other discussed alternatives.
See also: level=*
addr:block user defined node area The city block, if part of the address. In Japan, very few streets have names, so most housenumbers are associated with the block, not the street. See JA:住所#.E8.A1.97.E5.8C.BA_Block_number_address_system.E3.81.AB.E3.81.A4.E3.81.84.E3.81.A6

Multilingual Addresses

In areas with two or more official languages, addresses can be localized by adding a language code after the usual address keys like:

How language codes are selected is described in Multilingual_names.

Addresses without housenumbers

  • If there wasn’t a housenumber assigned to the address, you can use nohousenumber=yes
