iceaddr is a pure Python >=3.8 package to look up information about Icelandic streets, addresses, placenames, landmarks, locations and postcodes. The underlying data is contained in a local SQLite database assembled from the following sources:

• Staðfangaskrá, the official Icelandic address registry maintained by Registers Iceland (Þjóðskra, CC-BY)
• IS 50V Örnefni from the National Land Survey of Iceland (Landmælingar Íslands)
• The postcode table provided by Postur.is, with supplementary data from Icelandic Wikipedia

Since no networking takes place, lookups are very fast and can be performed offline. The package is useful for geocoding and reverse geocoding of Icelandic addresses and placenames, as well as for validating addresses and postcodes. No external dependencies are required.

The latest version of iceaddr is available via PyPI.

pip install iceaddr

>>> from iceaddr import iceaddr_lookup
>>> a = iceaddr_lookup('Austurstræti', number=14, postcode=101)
>>> pprint(a)
[{'bokst': '',
  'byggd': 1,
  'heiti_nf': 'Austurstræti',
  'heiti_tgf': 'Austurstræti',

  'svfnr': 0,
  'tegund': 'Þéttbýli',
  'vidsk': ''}]

>>> from iceaddr import iceaddr_lookup
>>> a = iceaddr_lookup('Öldugötu', number=4, placename='Reykjavík')
>>> pprint(a)
[{'bokst': '',
  'byggd': 1,
  'heiti_nf': 'Öldugata',
  'heiti_tgf': 'Öldugötu',

  'svfnr': 0,
  'tegund': 'Þéttbýli',
  'vidsk': ''}]

Street and place names can be provided in either nominative (nf.) or dative (þgf.) case (e.g. both 'Öldugata' and 'Öldugötu' will work, as will both 'Selfoss' and 'Selfossi').

Please note that iceaddr_lookup() returns a list of zero or more addresses matching the criterion.

>>> from iceaddr import iceaddr_lookup
>>> iceaddr_lookup('Dúfnahólar', number=10)
[]
>>> res = iceaddr_lookup('Öldugata', number=9)
>>> [(a['postnr'], a['stadur_nf']) for a in res]
[(101, 'Reykjavík'), (220, 'Hafnarfjörður'), (621, 'Dalvík')]

For natural search string queries, the module provides iceaddr_suggest():

>>> from iceaddr import iceaddr_suggest
>>> a = iceaddr_suggest('Öldugata 4, Rey')
>>> [n['stadur_tgf'] for n in a]
['Reykjavík', 'Reyðarfirði']
>>> a = iceaddr_suggest('Öldugö', limit=200)
>>> len(a)
151

The default limit on results from both functions is 50.

Given a set of WGS84 coordinates, the nearest_addr() function returns a list of the nearest addresses in the database:

>>> from iceaddr import nearest_addr
>>> addr = nearest_addr(64.148446, -21.944933)[0]
>>> print(f"{addr['heiti_nf']} {addr['husnr']}")
Öldugata 2

>>> from iceaddr import postcode_lookup
>>> postcode_lookup(400)
{   "svaedi_nf": "Vesturland og Vestfirðir",
    "svaedi_tgf": "Vesturlandi og Vestfjörðum",
    "stadur_nf": "Ísafjörður",
    "stadur_tgf": "Ísafirði",
    "tegund": "Þéttbýli"}
# Accepts string or int
>>> postcode_lookup("107")
{   "svaedi_nf": "Höfuðborgarsvæðið",
    "svaedi_tgf": "Höfuðborgarsvæðinu",
    "stadur_nf": "Reykjavík",
    "stadur_tgf": "Reykjavík",
    "tegund": "Þéttbýli",
    "lysing": "Vesturbær"}

>>> from iceaddr import POSTCODES
>>> pprint(POSTCODES[101])
{   "svaedi_nf": "Höfuðborgarsvæðið",
    "svaedi_tgf": "Höfuðborgarsvæðinu",
    "stadur_nf": "Reykjavík",
    "stadur_tgf": "Reykjavík",
    "tegund": "Þéttbýli",
    "lysing": "Miðborg"}

>>> from iceaddr import postcodes_for_placename
>>> postcodes_for_placename('Ísafjörður')
[400, 401]
>>> postcodes_for_placename('Kópavogi')
[200, 201, 202, 203]
>>> postcodes_for_placename('kópav', partial=True)
[200, 201, 202, 203]

>>> from iceaddr import postcodes_for_region
>>> postcodes_for_region('Norðurland')
[530, 531, 540, 541, 545, ...]
>>> postcodes_for_region('Höfuðborgarsvæðið')
[101, 102, 103, 104, 105, ...]

>>> from iceaddr import placename_lookup
>>> placename_lookup('Meðalfellsvatn')
[{'flokkur': 'Vatnaörnefni Mið',
  'id': 2339,
  'lat_wgs84': 64.3112049,
  'long_wgs84': -21.5997926,
  'nafn': 'Meðalfellsvatn'}]

If more than one placename match is found, the results are ordered by size, with precedence given to municipalities and densely populated areas.

>>> placename_lookup("Egilsstað", partial=True)
[{'flokkur': 'Þéttbýli',
  'id': 63208,
  'lat_wgs84': 65.2637152,
  'long_wgs84': -14.3931143,
  'nafn': 'Egilsstaðir'},
 {'flokkur': 'Landörnefni Lítið',
  'id': 108285,
  'lat_wgs84': 65.3516154,
  'long_wgs84': -20.610947,
  'nafn': 'Egilsstaðir'}]

Given a set of WGS84 coordinates, the nearest_placenames() function returns a list of the nearest placenames in the database:

>>> from iceaddr import nearest_placenames
>>> pn = nearest_placenames(64.148446, -21.944933, limit=1)[0]
>>> print(pn["nafn"])
Landakotsvöllur

To build your own version of the package, you need to have Python >=3.8 installed. Then, after (optionally) creating a virtual environment, run the following command from the repository root to install dependencies:

pip install ".[dev]"

Then run the following command to build the database:

bash build.sh

This creates an SQLite3 database in the repo root named iceaddr.db. Move this file to src/iceaddr/ and you can now install your own freshly built version of the package:

pip install .
