The various addr keys are used to provide address information for buildings and facilities. See Addresses for more details on usage.
How to map
Where to add the address
The address tagging should be added to
- the object
of a point of interest; - the polygon representing an area (building or campus/site outline) if the address is valid for the whole object (e.g. a detached house, an individual terraced house, a school campus);
- to a particular node sitting on the outline (e.g. entrance, gate) or contained within the object if the address applies to this point, in particular when an object has multiple addresses such as an apartment building with several entrances;
- to a node if you are unsure about the extent of the address.
What to add
As a minimum, please add
- addr:housenumber=* (or addr:housename=* when this is part of the postal address)
- addr:street=*
If you know them and if they exist, please add:
- addr:city=*
- addr:postcode=* (adding to single elements might depend on local mapping practices)
- addr:country=* (depending on the mapping practices in your country)
If they are part of the postal address, please add:
- addr:suburb=*
- addr:state=*
- addr:province=*
- addr:floor=*

A few mappers consider higher-level tags, or even addr:city=* as redundant, since they could be calculated from the respective boundary relations they are contained in (if present and valid). However, such practice has severe disadvantages and can lead to wrong results.
The focus on the usage of addr:country=* differs across national communities, some consider it as necessary part of tagging (Germany), some as unwanted tag (Poland).

Commonly used subkeys
| Key | Value | Element | Comment | Rendering | Photo | |
|---|---|---|---|---|---|---|
Tags for individual houses | ||||||
| addr:housenumber | user defined |
|
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 |
|
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 |
|
The unit numbers (a range or a list) of the flats or apartments located behind a single entrance door. | 
|
| |
| addr:conscriptionnumber | user defined |
|
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 |
|
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 |
|
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 |
|
The postal code of the building/area. Some mappers prefer to rely on boundary=postal_code | |||
| addr:city | user defined |
|
The name of the city as given in postal addresses of the building/area. (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.) Some mappers assume it can be derived from a boundary=administrative relation. |  | ||
| addr:country | user defined |
|
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". More or less favoured in different national communities. |
|||
| addr:full | user defined |
|
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 |
|
The hamlet of the object. |  | ||
| addr:suburb | user defined |
|
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 |
|
The subdistrict of the object. | |||
| addr:district | user defined |
|
The district of the object. | |||
| addr:province | user defined |
|
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 |
|
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 |
|
How to interpolate the house numbers belonging to the way along the respective street. See detailed description. |
 | ||
| addr:interpolation | Number n |
|
Every nth house between the end nodes is represented by the interpolation way. | |||
| addr:inclusion | actual/estimate/potential |
|
Optional tag to indicate the accuracy level of survey used to create the address interpolation way. See detailed description. |

| Key | Value | Element | Comment | Photo | Taginfo |
|---|---|---|---|---|---|
| Tags for parts of a building | |||||
| addr:door | user defined |
|
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 |
|
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 |
|
A list of flat numbers accessible in a building or behind a door. | ||
| addr:floor | Number |
|
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 |
|
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
